Bio of Grossadmiral Karl Dönitz

Karl Dönitz was born on 16 September 1891 in Grünau, near Berlin, to Anna Beyer and Emil Dönitz, an engineer. Karl had an older brother. In 1910, Dönitz enlisted in the Kaiserliche Marine ("Imperial Navy").

On 27 September 1913, Dönitz was commissioned as a Leutnant zur See (acting sub-lieutenant). When World War I began, he served on the light cruiser SMS Breslau in the Mediterranean Sea. In August 1914, the Breslau and the battlecruiser SMS Goeben were sold to the Ottoman Navy; the ships were renamed the Midilli and the Yavuz Sultan Selim, respectively. They began operating out of Constantinople, under Rear Admiral Wilhelm Souchon, engaging Russian forces in the Black Sea. On 22 March 1916, Dönitz was promoted to Oberleutnant zur See. He requested a transfer to the submarine forces, which became effective on 1 October 1916. He attended the submariner's school at Flensburg-Mürwik and passed out on 3 January 1917. He served as watch officer on U-39, and from February 1918 onward as commander of UC-25. On 2 July 1918, he became commander of UB-68, operating in the Mediterranean. On 4 October, after suffering technical difficulties, Dönitz was forced to surface and scuttled his boat. He was captured by the British and incarcerated in the Redmires camp near Sheffield. He remained a prisoner of war until 1919 and in 1920 he returned to Germany.

On 27 May 1916, Dönitz married a nurse named Ingeborg Weber (1893–1962), the daughter of German general Erich Weber (1860–1933). They had three children whom they raised as Protestant Christians: daughter Ursula (1917–1990) and sons Klaus (1920–1944) and Peter (1922–1943). Both of Dönitz's sons were killed during the Second World War. Peter was killed on 19 May 1943 when U-954 was sunk in the North Atlantic with all hands.

Hitler had issued a policy stating that if a senior officer such as Dönitz lost a son in battle and had other sons in the military, the latter could withdraw from combat and return to civilian life. After Peter's death, Klaus was forbidden to have any combat role and was allowed to leave the military to begin studying to become a naval doctor. He returned to sea and was killed on 13 May 1944; he had persuaded his friends to let him go on the E-boat S-141 for a raid on Selsey on his 24th birthday. The boat was sunk by the French destroyer La Combattante.

He continued his naval career in the naval arm of the Weimar Republic's armed forces. On 10 January 1921, he became a Kapitänleutnant (lieutenant) in the new German navy (Vorläufige Reichsmarine). Dönitz commanded torpedo boats, becoming a Korvettenkapitän (lieutenant-commander) on 1 November 1928. On 1 September 1933, he became a Fregattenkapitän (commander) and, in 1934, was put in command of the cruiser Emden, the ship on which cadets and midshipmen took a year-long world cruise as training.

In 1935, the Reichsmarine was renamed Kriegsmarine. Germany was prohibited by the Treaty of Versailles from possessing a submarine fleet. The Anglo-German Naval Agreement of 1935 allowed submarines and he was placed in command of the U-boat flotilla Weddigen, which comprised three boats; U-7; U-8 and; U-9. On 1 September 1935, he was promoted to Kapitän zur See (naval captain).

Dönitz opposed Raeder's views that surface ships should be given priority in the Kriegsmarine during the war, but in 1935 Dönitz doubted U-boat suitability in a naval trade war on account of their slow speed. This phenomenal contrast with Dönitz's wartime policy is explained in the 1935 Anglo-German Naval Agreement. The accord was viewed by the navy with optimism, Dönitz included. He remarked, "Britain, in the circumstances, could not possibly be included in the number of potential enemies." The statement, made after June 1935, was uttered at a time when the naval staff were sure France and the Soviet Union were likely to be Germany's only enemies. Dönitz's statement was partially correct. Britain was not foreseen as an immediate enemy, but the navy still held onto a cadre of imperial officers, which along with its Nazi-instigated intake, understood war would be certain in the distant future, perhaps not until the mid-1940s.

Dönitz came to recognise the need for more of these vessels. Only 26 were in commission or under construction that summer. In the time before his command of submarines, he perfected the group tactics that first appealed to him in 1917. At this time Dönitz first expressed his procurement policies. His preference for the submarine fleet was in the production of large numbers of small craft. In contrast to other warships, the fighting power of the U-boat, in his opinion, was not dependent on its size as the torpedo, not the gun, was the machine's main weapon. Dönitz had a tendency to be critical of larger submarines and listed a number of disadvantages in their production, operation and tactical use. Dönitz recommended the Type VII submarine as the ideal submarine. The boat was reliable and had a range of 6,200 miles. Modifications lengthened this to 8,700 miles.

Dönitz revived Hermann Bauer's idea of grouping several submarines together into a Rudeltaktik ("pack tactic", commonly called "wolfpack") to overwhelm a merchant convoy's escorts. Implementation of wolfpacks had been difficult in World War I owing to the limitations of available radios. In the interwar years, Germany had developed ultra high frequency transmitters, (ukw) while the Enigma cipher machine was believed to have made communications secure. A 1922 paper written by Kapitäinleutnant Wessner of the Wehrabteilung (Defence Ministry) pointed to the success of surface attacks at night and the need to coordinate operations with multiple boats to defeat the escorts. Dönitz knew of the paper and improved the ideas suggested by Wessner. This tactic had the added advantage that a submarine on the surface was undetectable by ASDIC (an early form of sonar). Dönitz claimed after the war he would not allow his service to be intimidated by British disclosures about ASDIC and the course of the war had proven him right. In reality, Dönitz harboured fears stretching back to 1937 that the new technology would render the U-boat impotent. Dönitz published his ideas on night attacks in January 1939 in a booklet called Die U-Bootwaffe which apparently went unnoticed by the British. The Royal Navy's overconfidence in Asdic encouraged the Admiralty to suppose it could deal with submarines whatever strategy they adopted — in this they were proven wrong; submarines were difficult to locate and destroy under operational conditions.

In 1939 he expressed his belief that he could win the war with 300 vessels. The Nazi leadership's rearmament priorities were fundamentally geared to land and aerial warfare. From 1933 to 1936, the navy was granted only 13 per cent of total armament expenditure. The production of U-boats, despite the existing Z Plan, remained low. In 1935 shipyards produced 14 submarines, 21 in 1936, 1 in 1937. In 1938 nine were commissioned and in 1939 18 U-boats were built. Dönitz's vision may have been misguided. The British had planned for contingency construction programmes for the summer, 1939. At least 78 small escorts and a crash construction programme of "Whale catchers" had been invoked. The British, according to one historian, had taken all the sensible steps necessary to deal with the U-boat menace as it existed in 1939 and were well placed to deal with large numbers of submarines, prior to events in 1940.

On 1 September 1939, Germany invaded Poland. Britain and France soon declared war on Germany, and World War II began. On Sunday 3 September, Dönitz chaired a conference at Wilhelmshaven. At 11:15 am the British Admiralty sent out a signal "Total Germany". B-Dienst intercepted the message and it was promptly reported to Dönitz. Dönitz paced around the room and his staff purportedly heard him repeatedly say, "My God! So it's war with England again!"

Dönitz abandoned the conference to return within the hour a far more composed man. He announced to his officers, "we know our enemy. We have today the weapon and a leadership that can face up to this enemy. The war will last a long time; but if each does his duty we will win." Dönitz had only 57 boats; of those, 27 were capable of reaching the Atlantic Ocean from their German bases. A small building program was already under way but the number of U-boats did not rise noticeably until the autumn of 1941.

Dönitz's first major action was the cover up of the sinking of the British passenger liner Athenia later the same day. Acutely sensitive to international opinion and relations with the United States, the death of more than a hundred civilians was damaging. Dönitz suppressed the truth that the ship was sunk by a German submarine. He accepted the commander's explanation that he genuinely believed the ship was armed. Dönitz ordered the engagement to be struck from the submarine's logbook. Dönitz did not admit the cover up until 1946.

Hitler's original orders to wage war only in accordance with the Prize Regulations were not issued in any altruistic spirit but in the belief hostilities with the Western Allies would be brief. On 23 September 1939, Hitler, on the recommendation of Admiral Raeder, approved that all merchant ships making use of their wireless on being stopped by U-boats should be sunk or captured. This German order marked a considerable step towards unrestricted warfare. Four days later enforcement of Prize Regulations in the North Sea was withdrawn; and on 2 October complete freedom was given to attack darkened ships encountered off the British and French coasts. Two days later the Prize Regulations were cancelled in waters extending as far as 15° West, and on 17 October the German Naval Staff gave U-boats permission to attack without warning all ships identified as hostile. The zone where darkened ships could be attacked with complete freedom was extended to 20° West on 19 October. Practically the only restrictions now placed on U-boats concerned attacks on passenger liners and, on 17 November, they too were allowed to be attacked without warning if clearly identifiable as hostile.

Although the phrase was not used, by November 1939 the BdU was practicing unrestricted submarine warfare. Neutral shipping was warned by the Germans against entering the zone which, by American neutrality legislation, was forbidden to American shipping, and against steaming without lights, zigzagging or taking any defensive precautions. The complete practice of unrestricted warfare was not enforced for fear of antagonising neutral powers, particularly the Americans. Admirals Raeder and Dönitz and the German Naval Staff had always wished and intended to introduce unrestricted warfare as rapidly as Hitler could be persuaded to accept the possible consequences.

Dönitz and Raeder accepted the death of the Z Plan upon the outbreak of war. The U-boat programme would be the only portion of it to survive 1939. Both men lobbied Hitler to increase the planned production of submarines to at least 29 per month. The immediate obstacle to the proposals was Hermann Göring, head of the Four Year Plan, commander-in-chief of the Luftwaffe and future successor to Hitler. Göring would not acquiesce and in March 1940 Raeder was forced to drop the figure from 29 to 25, but even that plan proved illusory. In the first half of 1940, two boats were delivered, increased to six in the final half of the year. In 1941 the deliveries increased to 13 to June, and then 20 to December. It was not until late 1941 the number of vessels began to increase quickly. From September 1939 through to March 1940, 15 U-boats were lost—nine to convoy escorts. The impressive tonnage sunk had little impact on the Allied war effort at that point.

On 1 October 1939, Dönitz became a Konteradmiral (rear admiral) and "Commander of the Submarines" (Befehlshaber der Unterseeboote, BdU). For the first part of the war, despite disagreements with Raeder where best to deploy his men, Dönitz was given considerable operational freedom for his junior rank.

From September–December 1939 U-boats sank 221 ships for 755,237 gross tons, at the cost of nine U-boats. Only 47 merchant ships were sunk in the North Atlantic, a tonnage of 249,195. Dönitz had difficulty in organising Wolfpack operations in 1939. A number of his submarines were lost en route to the Atlantic, through either the North Sea or the heavily defended English Channel. Torpedo failures plagued commanders during convoy attacks. Along with successes against single ships, Dönitz authorised the abandonment of pack attacks in the autumn. The Norwegian Campaign amplified the defects. Dönitz wrote in May 1940, "I doubt whether men have ever had to rely on such a useless weapon." He ordered the removal of magnetic pistols in favour of contact fuses and their faulty depth control systems. In no fewer than 40 attacks on Allied warships, not a single sinking was achieved. The statistics show that from the outbreak of war to approximately the spring, 1940, faulty German torpedoes saved 50–60 ships equating to 300,000 GRT.

Dönitz was encouraged in operations against warships by the sinking of the aircraft carrier Courageous. On 28 September 1939 he said, "it is not true Britain possesses the means to eliminate the U-boat menace." The first specific operation—named "Special Operation P"—authorised by Dönitz was Günther Prien's attack on Scapa Flow, which sank the battleship Royal Oak. The attack became a propaganda success though Prien purportedly was unenthusiastic about being used that way. Stephen Roskill wrote, "It is now known that this operation was planned with great care by Admiral Dönitz, who was correctly informed of the weak state of the defences of the eastern entrances. Full credit must also be given to Lieutenant Prien for the nerve and determination with which he put Dönitz's plan into execution."

In May 1940, 101 ships were sunk—but only nine in the Atlantic—followed by 140 in June; 53 of them in the Atlantic for a total of 585,496 GRT that month. The first six months in 1940 cost Dönitz 15 U-boats. Until mid-1940 there remained a chronic problem with the reliability of the G7e torpedo. As the battles of Norway and Western Europe raged, the Luftwaffe sank more ships than the U-boats. In May 1940, German aircraft sank 48 ships (158 GRT), three times that of German submarines. The Allied evacuations from western Europe and Scandinavia in June 1940 attracted Allied warships in large numbers, leaving many of the Atlantic convoys travelling through the Western Approaches unprotected. From June 1940, the German submarines began to exact a heavy toll. In the same month, the Luftwaffe sank just 22 ships (195,193 GRT) in a reversal of the previous months.

Germany's defeat of Norway gave the U-boats new bases much nearer to their main area of operations off the Western Approaches. The U-boats operated in groups or 'wolf packs' which were coordinated by radio from land. With the fall of France, Germany acquired U-boat bases at Lorient, Brest, St Nazaire, and La Pallice/La Rochelle and Bordeaux. This extended the range of Type VIIs. Regardless, the war with Britain continued. The admiral remained sceptical of Operation Sea Lion, a planned invasion and expected a long war. The destruction of seaborne trade became German strategy against Britain after the defeat of the Luftwaffe in the Battle of Britain. Hitler was content with The Blitz and cutting off Britain's imports. Dönitz gained importance as the prospect of a quick victory faded. Dönitz concentrated groups of U-boats against the convoys and had them attack on the surface at night. In addition the Germans were helped by Italian submarines which in early 1941 actually surpassed the number of German U-boats. Having failed to persuade the Nazi leadership to prioritise U-boat construction, a task made more difficult by military victories in 1940 which convinced many people that Britain would give up the struggle, Dönitz welcomed the deployment of 26 Italian submarines to his force. Dönitz complimented Italian bravery and daring, but was critical of their training and submarine designs. Dönitz remarked they lacked the necessary toughness and discipline and consequently were "of no great assistance to us in the Atlantic."

The establishment of German bases on the French Atlantic coast allowed for the prospect of aerial support. Small numbers of German aircraft, such as the long-range Focke-Wulf Fw 200, sank a large number of ships in the Atlantic in the last quarter of 1940. In the long term, Göring proved an insurmountable problem in effecting cooperation between the navy and the Luftwaffe. In early 1941, while Göring was on leave, Dönitz approached Hitler and secured from him a single bomber/maritime patrol unit for the navy. Göring succeeded in overturning this decision and both Dönitz and Raeder were forced to settle for a specialist maritime air command under Luftwaffe control. Poorly supplied, Fliegerführer Atlantik achieved modest success in 1941, but thereafter failed to have an impact as British counter-measures evolved. Cooperation between the Kriegsmarine and Luftwaffe remained dysfunctional to the war's end. Göring and his unassailable position at the Reichsluftfahrtministerium (Air Ministry) prevented all but limited collaboration.

The U-boat fleet's successes in 1940 and early 1941 were spearheaded by a small number of highly trained and experienced pre-war commanders. Otto Kretschmer, Joachim Schepke, and Günther Prien were the most famous, but others included Hans Jenisch, Victor Oehrn, Engelbert Endrass, Herbert Schultze and Hans-Rudolf Rösing. Although skilled and with impeccable judgement, the shipping lanes they descended upon were poorly defended. The U-boat force did not escape unscathed. Within the space of several days in March 1941, Prien and Schepke were dead and Kretschmer was a prisoner. All of them fell in battle with a convoy system. The number of boats in the Atlantic remained low. Six fewer existed in May 1940 than in September 1939. In January 1941 there were just six on station in the Atlantic—the lowest during the war, while still suffering from unreliable torpedoes. Dönitz insisted that operations continue while "the smallest prospect of hits" remained.

For his part, Dönitz was involved in the daily operations of his boats and all the major operational level decisions. His assistant, Eberhard Godt, was left to manage daily operations as the war continued. Dönitz was debriefed personally by his captains which helped establish a rapport between leader and led. Dönitz neglected nothing that would make the bond firmer. Often there would be a distribution of medals or awards. As an ex-submariner, Dönitz did not like to contemplate the thought of a man who had done well heading out to sea, perhaps never to return, without being rewarded or receiving recognition. Dönitz acknowledged where decorations were concerned there was no red tape and that awards were "psychologically important".

Intelligence played an important role in the Battle of the Atlantic. In general, BdU intelligence was poor. Counter-intelligence was not much better. At the height of the battle in mid-1943 some 2,000 signals were sent from the 110 U-boats at sea. Radio traffic compromised his ciphers by giving the Allies more messages to work with. Furthermore, replies from the boats enabled the Allies to use High-frequency direction finding (HF/DF, called "Huff-Duff") to locate a U-boat using its radio, track it and attack it. The over-centralised command structure of BdU and its insistence on micro-managing every aspect of U-boat operations with endless signals provided the Allied navies with enormous intelligence. The enormous "paper chase" [cross-referencing of materials] operations pursued by Allied intelligence agencies was not thought possible by BdU. The Germans did not suspect the Allies had identified the codes broken by B-Dienst. Conversely, when Dönitz suspected the enemy had penetrated his own communications BdU's response was to suspect internal sabotage and reduce the number of the staff officers to the most reliable, exacerbating the problem of over-centralisation. In contrast to the Allies, the Wehrmacht was suspicious of civilian scientific advisors and generally distrusted outsiders. The Germans were never as open to new ideas or thinking of war in intelligence terms. According to one analyst BdU "lacked imagination and intellectual daring" in the naval war. These Allied advantages failed to avert heavy losses in the June 1940 – May 1941 period, known to U-boat crews as the "First Happy Time." In June 1941, 68 ships were sunk in the North Atlantic (318,740 GRT) at a cost of four U-boats, but the German submarines would not eclipse that number for the remainder of the year. Just 10 transports were sunk in November and December 1941.

On 7 May 1941, the Royal Navy captured the German Arctic meteorological vessel München and took its Enigma machine intact, this allowed the Royal Navy to decode U-boat radio communications in June 1941. Two days later the capture of U-110 was an intelligence coup for the British. The settings for high-level "officer-only" signals, "short-signals" (Kurzsignale) and codes standardising messages to defeat HF/DF fixes by sheer speed were found. Only the Hydra settings for May were missing. The papers were the only stores destroyed by the crew. The capture on 28 June of another weather ship, Lauenburg, enabled British decryption operations to read radio traffic in July 1941. Beginning in August 1941, Bletchley Park operatives could decrypt signals between Dönitz and his U-boats at sea without any restriction. The capture of the U-110 allowed the Admiralty to identify individual boats, their commanders, operational readiness, damage reports, location, type, speed, endurance from working up in the Baltic to Atlantic patrols. On 1 February 1942, the Germans had introduced the M4 cipher machine, which secured communications until it was cracked in December 1942. Even so, the U-boats achieved their best success against the convoys in March 1943, due to an increase in U-boat numbers, and the protection of the shipping lanes was in jeopardy. Due to the cracked M4 and the use of radar, the Allies began to send air and surface reinforcements to convoys under threat. The shipping lanes were secured, which came as a great surprise to Dönitz. The lack of intelligence and increased numbers of U-boats contributed enormously to Allied losses that year.

Signals security aroused Dönitz's suspicions during the war. On 12 January 1942 German supply submarine U-459 arrived 800 nautical miles west of Freetown, well clear of convoy lanes. It was scheduled to rendezvous with an Italian submarine, until intercepted by a warship. The German captain's report coincided with reports of a decrease in sightings and a period of tension between Dönitz and Raeder. The number of U-boats in the Atlantic, by logic, should have increased, not lowered the number of sightings and the reasons for this made Dönitz uneasy. Despite several investigations, the conclusion of the BdU staff was that Enigma was impenetrable. His signals officer responded to the U-459 incident with answers ranging from coincidence, direction finding to Italian treachery. General Erich Fellgiebel, Chief Signal Officer of Army High Command and of Supreme Command of Armed Forces (Chef des Heeresnachrichtenwesens), apparently concurred with Dönitz. He concluded that there was "convincing evidence" that, after an "exhaustive investigation" that the Allied codebreakers had been reading high level communications. Other departments in the navy downplayed or dismissed these concerns. They vaguely implied "some components" of Enigma had been compromised, but there was "no real basis for acute anxiety as regards any compromise of operational security".

Following Hitler's declaration of war on the United States on 11 December 1941, Dönitz implemented Operation Drumbeat (Unternehmen Paukenschlag). The entry of the United States benefited German submarines in the short term. Dönitz intended to strike close to shore in American and Canadian waters and prevent the convoys—the most effective anti–U-boat system—from ever forming. Dönitz was determined to take advantage of Canadian and American unpreparedness before the situation changed.

The problem inhibiting Dönitz's plan was a lack of boats. On paper he had 259, but in January 1942, 99 were still undergoing sea trials and 59 were assigned to training flotillas, leaving only 101 on war operations. 35 of these were under repair in port, leaving 66 operational, of which 18 were low on fuel and returning to base, 23 were en route to areas where fuel and torpedoes needed to be conserved, and one was heading to the Mediterranean. Therefore, on 1 January Dönitz had a fighting strength of 16–25 in the Atlantic (six near to Iceland on "Norwegian operations"), three in the Arctic Ocean, three in the Mediterranean and three operating west of Gibraltar. Dönitz was severely limited to what he could accomplish in American waters in an initial offensive.

From 13 January 1942, Dönitz planned to begin a surprise offensive from the Gulf of Saint Lawrence to Cape Hatteras. Unknown to him, Ultra had read his Enigma signals and knew the position, size, and intentions of his boats, down to the date the operation was scheduled to begin. The attacks, when they came, were not a surprise. Of the 12 U-boats that began the offensive from the Grand Banks southward, just two survived the war. The operation began the Battle of the St. Lawrence, a series of battles which lasted into 1944. It remained possible for a U-boat to operate in the Gulf into 1944, but countermeasures were strong. In 1942, the global ratio of ships-to-U-boats sunk in Canadian waters was 112:1. The global average was 10.3:1. The solitary kill was achieved by the RCAF. Canadian operations, as with American efforts, were a failure during this year.

Along with conventional U-boat operations Dönitz authorised clandestine activities in Canadian waters, including spying, mine-laying, and recovery of German prisoners of war (as Dönitz wished to extract information from rescued submariners concerning Allied tactics). All of these things tied down Canadian military power and imposed industrial, fiscal, and psychological costs. The impunity with which U-boats carried out these operations in Canadian waters into 1944 provided a propaganda effect. One of these operations was the well-known Operation Kiebitz to rescue Otto Kretschmer.

Even with operational problems great success was achieved in American waters. From January to July 1942, Dönitz's submarines were able to attack unescorted ships off the United States' east coast and in the Caribbean Sea; U-boats sank more ships and tonnage than at any other time in the war. After a convoy system was introduced to protect the shipping, Dönitz shifted his U-boats back to the North Atlantic. The period, known in the U-boat Arm as the "Second Happy Time", represented one of the greatest naval disasters of all time, and largest defeat suffered by American sea power. The success was achieved with only five U-boats initially which sank 397 ships in waters protected by the United States Navy with an additional 23 sunk at the Panama Sea Frontier. Dönitz put the successes down to the American failure to initialize a blackout along the East Coast of the United States and ship captains' insistence on following peace-time safety procedures. The failure to implement a blackout stemmed from the American government's concern it would affect tourism trade. Dönitz wrote in his memoirs that the lighthouses and buoys "shone forth, though perhaps a little less brightly than usually".

By the time improved American air and naval defences had driven German submarines from American shores, 5,000 Allied sailors had been killed for negligible losses in U-boats. Dönitz ordered simultaneous operations in the Caribbean Sea. The ensuing Battle of the Caribbean resulted in immediate dividends for U-boats. In a short time, at least 100 transports had been destroyed or sunk. The sinkings damaged inter-island trade substantially. Operation Neuland was among the most damaging naval campaigns in the region. Oil refinery production in region declined while the tanker fleet suffered losses of up to ten per cent within twenty-four hours. However, ultimately Dönitz could not hope to sink more ships than American industry could build, so he targeted the tanker fleet in the Caribbean and Gulf of Mexico in the hope that depleting oil transports would paralyze shipyard output. 33 transports were sunk in July before Dönitz lost his first crew. The USN introduced effective convoy systems thereafter, ending the "carnage".

Dönitz maintained his demands for the concentration of all his crews in the Atlantic. As the military situation in North Africa and on the Eastern Front began to deteriorate Hitler diverted a number of submarines to the Battle of the Mediterranean upon the suggestions of Admiral Eberhard Weichold. Raeder and Dönitz resisted the deployment to the Mediterranean to no avail. Hitler felt compelled to act against Allied sea forces which were having an enormous impact on Axis supply lines to North Africa. The decision defied logic, for a victory in the Atlantic would end the war in the Mediterranean. The U-boat war in the Mediterranean was a costly failure, despite successes against warships. Approximately 60 crews were lost and only one crew managed to withdraw through the Strait of Gibraltar. Albrecht Brandi was one of Dönitz's highest performers but his record is a matter of controversy; post-war records prove systematic over-claiming of sinkings. He survived his boat's sinking and was smuggled to Germany through Spain. Dönitz had met his end as a submarine commander in the Mediterranean two decades earlier.

In 1942 Dönitz summed up his philosophy in one simple paragraph; "The enemy's shipping constitutes one single, great entity. It is therefore immaterial where a ship is sunk. Once it has been destroyed it has to be replaced by a new ship; and that's that." The remark was the green light to unrestricted submarine warfare and began the tonnage war proper. BdU intelligence concluded the Americans could produce 15,300,000 tons of shipping in 1942 and 1943—two million tons under actual production figures. Dönitz always calculated the worst-case scenario using the highest figures of enemy production potential. Some 700,000 tons per month needed to be sunk to win the war. The "second happy time" reached a peak in June 1942, with 325,000 tons sunk, up from 311,000 in May, 255,000 in April and the highest since the 327,000 tons sunk in March 1942. With support from the Royal Navy and Royal Canadian Navy, the new convoy systems compelled Dönitz to withdraw his captains to the mid-Atlantic once again. Nevertheless, there was still cause for optimism. B-Dienst had cracked the convoy ciphers and by July 1942 he could call upon 311 boats, 140 operational, to conduct a renewed assault. By October 1942 he had 196 operational from 365. Dönitz's force finally reached the desired number both he and Raeder had hoped for in 1939. Unaware of it, Dönitz and his men were aided by the Ultra blackout. The addition of a fourth rotor to the Enigma left radio detection the only way to gather intelligence on dispositions and intentions of the German naval forces. German code breakers had their own success in the capture of the code book to Cipher Code Number 3 from a merchant ship. It was a treble success for the BdU.

Dönitz was content that he now had the naval power to extend U-boat operations to other areas aside the North Atlantic. The Caribbean, Brazilian waters with the coast of West Africa designated operational theatres. Waters in the southern hemisphere to South Africa could also be attacked with the new Type IX submarine. The strategy was sound and his tactical ideas were effective. The number of boats available allowed him to form Wolfpacks to comb convoy routes from east to west attacking one when found and pursuing it across the ocean. The pack then refuelled from a U-boat tanker and worked from west to east. Raeder and the operations staff disputed the value in attacking convoys heading westward with empty cargo holds. The tactics were successful but placed great strain on crews who spent up to eight days in constant action.

November 1942 was a new high in the Atlantic. 134 ships were sunk for 807,754 tons. 119 were destroyed by submarines, 83 (508,707 tons) in the Atlantic. The same month Dönitz suffered strategic defeat. His submarines failed to prevent Operation Torch, even with 196 of them operating in the Atlantic. Dönitz considered it a major self-inflicted defeat. Allied morale radically improved after the victories of Torch, the Second Battle of El Alamein and the Battle of Stalingrad; all occurred within days of one another. The U-boat war was the only military success the Germans enjoyed at the end of the year.

On 30 January 1943, Dönitz replaced Erich Raeder as Commander-in-chief of the navy (Oberbefehlshaber der Kriegsmarine) and Großadmiral (grand admiral) of the Naval High Command (Oberkommando der Marine). In a communique to the navy he announced his intentions to retain practical control of the U-boats and his desire to fight to the end for Hitler. Dönitz's inability to delegate control of the U-boat service has been construed as a weakness in the U-boat arm, contributing to the perception that Dönitz was an "impatient warrior", preoccupied with fighting battles and tactics rather than a strategist or organiser.

Dönitz's promotion earned Hitler his undying loyalty. For Dönitz, Hitler had given him a "true home-coming at last, to a country in which unemployment appeared to have been abolished, the class war no longer tore the nation apart, and the shame of defeat in 1918 was being expunged." When war came, Dönitz became more firmly wedded to his Nazi faith. Hitler recognised his patriotism, professionalism but above all, his loyalty. Dönitz remained so, long after the war was lost. In so doing, he wilfully ignored the genocidal nature of the regime and claimed ignorance of the Holocaust.

In the last quarter of 1942, 69 submarines had been commissioned taking the total number to 393, with 212 operational. Dönitz was not satisfied and immediately began a naval construction programme which in contrast to Raeder's, laid all its emphasis on torpedo boats and submarines. Dönitz's proposed expansion ran into difficulties experienced by all of his predecessors; the lack of steel. The navy had no representation on Albert Speer's armaments ministry, for naval production was the only sphere not under his control. Dönitz understood this worked against the navy because it lacked the elasticity to cope with breakdowns of production at any point, whereas the other services could make good production by compensating one sector at the expense of another. Without any representatives the battle of priorities was left to Speer and Göring. Dönitz had the sense to place U-boat production under Speer on the provision 40 per month were completed. Dönitz persuaded Hitler not to scrap the surface fleet capital ships, though they played no role in the Atlantic during his time in command. Dönitz reasoned the destruction of the surface fleet would provide the British with a victory and heap pressure on the U-boats, for these warships were tying down British air and naval forces that would otherwise be sent into the Atlantic.

New construction procedures, dispensing with prototypes and the abandonment of modifications reduced construction times from 460,000-man hours to 260–300,000 to meet Speer's quota. In the spring 1944, the Type XXI submarine was scheduled to reach frontline units. In 1943 the Combined Bomber Offensive undid German plans. Dönitz and Speer were appalled by the destruction of Hamburg, a major construction site. The battles of 1943 and 1944 were fought with the existing Type VII and Type IX submarines. The Type VII remained the backbone of the fleet in 1943.

At the end of 1942, Dönitz was faced with the appearance of escort carriers, and long-range aircraft working with convoy escorts. To protect his boats against the latter, he ordered his boats to restrict their operations to the Mid-Atlantic Gap, a stretch of ocean out of the range of land-based aircraft. Allied air forces had few aircraft equipped with ASV radar for U-boat detection into April and May 1943, and such units would not exist in Newfoundland until June. Convoys relied on RAF Coastal Command aircraft operating from Northern Ireland and Iceland. The aircraft imposed restraints on U-boat captains, who feared them for their ability to sink a submarine or alert surface warships to their position. In 1942 Coastal Command began forming units combined with ASV and Leigh Light to attack U-boats at night in transit to the Atlantic via the Bay of Biscay, which continued into 1943. The Command was moderately successful after mid-1942.

1943 began with continued tactical success for Dönitz in battle. In January Convoy TM 1 was nearly destroyed. The loss of 100,000 tons of fuel in one convoy represented the most devastating loss percentage of the war—only two of nine tankers reached port. The Eighth Army were forced to ration their fuel for a time, earning Dönitz the gratitude of the Afrika Korps. The Casablanca Conference, held that month, identified the Atlantic as the priority. It was agreed that until the defeat of Dönitz and his men, there could be no amphibious landings in continental Europe. Unknown to Dönitz, Bletchley Park had broken the Shark cypher and restored the flow of Enigma information; the Admiralty was able to route convoys around wolfpacks. During January and February 1943 information was decrypted within 24 hours proving operationally useful, although this slipped at the end of the second month contributing to German interceptions. Even so, in appalling weather, the Germans sank only 44 ships during the month, even with 100 U-boats at sea, the majority stationed in the mid-Atlantic gap.

In February 1943 the strength of Allied defences were ominous for Dönitz. The battle of convoy HX 224 was ended upon the intervention of air power from Iceland. Dönitz sent 20 boats to attack SC 118 and both sides suffered heavy losses—11 merchant ships for three U-boats plus four damaged. It was "what both sides considered one of the hardest fought battles of the Atlantic war". Despite sending 20 crews into action, Dönitz was concerned that most captains did not press home attacks. The majority of the ships sunk were by one crew, commanded by Siegfried von Forstner—he sank seven.

In March, Convoy SC 121 was attacked by 31 U-boats in two patrol lines. It was the most successful battle of the war for Dönitz. The battle of Convoys HX 229/SC 122 was the largest convoy battle, with 40 U-boats involved. Each operation was successful but all were fought in the mid-Atlantic. Allied losses reached a peak in March 1943. The Admiralty later issued a report on the matter; "The Germans never came so near [to] disrupting communications between the new world and the old as in the first twenty days of March 1943." Dönitz later conceded the March battles were to be the U-boats' last victories. New Allied techniques, tactics and technology began to turn the tide. By April 1943 U-boat morale was reaching a crisis point. Ninety-eight new boats were sent into the Atlantic that month and although the training was thorough the crews were inexperienced and it showed. Fifteen U-boats were destroyed in March 1943 and another 15 in April. Werner Hartenstein and Johann Mohr were notable casualties over the course of these eight weeks; the former's decision to rescue survivors of a sunken ship led to Dönitz's Laconia Order, which later formed part of the criminal case against Dönitz.

Ominous for BdU was the sudden growth of Allied air power. The Allied command accepted that air cover over the mid-Atlantic was inadequate and had drawn attention to the fact that not one VLR (Very Long Range) aircraft was to be found at any Allied air base west of Iceland. The Americans released 255 Liberators for the North Atlantic. At the end of March 1943 20 VLR aircraft were operational rising to 41 by mid-April, all of them flown by British crews. Twenty-eight anti-submarine and 11 anti-shipping squadrons were available to RAF Coastal Command, 619 aircraft in all—a striking change since September 1939. The influx of radar equipped aircraft into mid-Atlantic was matched by air patrols over the Bay of Biscay. Dönitz detected a drop in morale among his captains, as did the British. Dönitz encouraged his commanders to show a "hunter's instinct" and "warrior spirit" in the face of the air–surface support group threat.

Along with air power, the BdU was forced to contend with a large increase in Allied convoy escorts which fuelled from tankers in the convoys allowing escort across the ocean. The escort carrier support groups, protected by destroyers, which, in the words of the official naval historian of the Second World War, proved decisive; "it was the advent of the Support Groups, the Escort Carriers and the Very Long Range Aircraft which turned the tables on the U-boats-and did so with astonishing rapidity".

A hundred and eight ships were sunk in the first 20 days of March, and just 15 in the last 10. The official naval historian wrote, "The collapse of the enemy's offensive, when it came, was so sudden that it took him completely by surprise. We now know that, in fact, a downward trend in the U-boats' recent accomplishments could have forewarned him, but was concealed from him by the exaggerated claims made by their commanders." In April Dönitz lost five crews to the Coastal Command ASV Biscay offensive. Encouraged by the isolated successes of anti-aircraft artillery installed on submarines, he ordered crews to stay on the surface and fight it out with the aircraft. The decision caused casualties—four boats were lost in the first week of May alone, and three more by the end.

For the month of April Allied losses fell to 56 ships of 327,943 tons. In May 1943 the battle reached a climax with the battles of Convoy ONS 5, Convoy SC 129, Convoy SC 130. Throughout the battles only two ships were sunk in convoy in the Atlantic while an air anti-submarine escort was present. Dönitz depended on the surface manoeuvrability of his U-boats to locate targets, assemble wolfpacks and the complicated business of positioning his forces ahead of a convoy for an attack. Allied air power determined where and when U-boats could move freely on the surface. It was the combination of convoy escorts and air power that made the Atlantic unsuitable for pack operations. The US Navy introduced the K-class blimp. They forced a commander to dive to prevent the aircraft marking his position or attacking. From 10 to 24 May 1943, ten convoys passed through the mid-Atlantic. Six of the 370 ships were sunk; three were stragglers. Thirteen U-boats were sunk; four by warships, seven by aircraft, and two shared.

By 24 May, when Dönitz conceded defeat and withdrew the surviving crews from the field of battle, they had already lost 33 U-boats. At the end of May it had risen to 41. Dönitz tried to limit the damage to morale by declaring that the withdrawal was only temporary "to avoid unnecessary losses in a period when our weapons are shown to be at a disadvantage" and that "the battle in the north Atlantic—the decisive area—will be resumed". Dönitz did make a further attempt to regain the initiative, but the battle never reached the same pitch of intensity or hung in the balance, as during the spring of 1943. The Allied success won the Battle of the Atlantic. On 24 May Dönitz ordered the suspension of Atlantic operations, bringing an end to Black May.

Defeat in the mid-Atlantic left Dönitz in a dilemma. The U-boats had proven unable to elude convoy escorts and attack convoys with success. He was concerned about crew morale suffering from idleness and a loss of experience with the latest Allied developments in anti-submarine warfare. Aside from problems of seaworthiness among machines and crew, there were not enough Submarine pens to store idle boats and they were a target for aircraft in port. Dönitz would not withdraw his submarines from combat operations, for he felt the ships, men and aircraft engaged in suppressing the U-boats could then be turned on Germany directly; the U-boat war was to continue.

From mid-June 1943 the technological and industrial superiority of the Allied navies allowed the Americans, Canadians, and British to form hunter-killer groups consisting of fast anti-submarine escorts and aircraft carriers. The purpose of naval operations changed from avoiding U-boats and safeguarding convoys to seeking them out and destroying them wherever they operated. USN hunter-killer groups operated throughout the Atlantic. Argentia had been an important base for the naval taskforces until superseded by the Royal Canadian Navy in early 1943. U-boat operations were "crushed" by these task forces: 14 were sunk and only two of seven crews operating in Brazilian waters returned to Germany.

Dönitz reacted by deploying his U-boats near the Azores where land-based aircraft still had difficulty reaching them. In this region he hoped to threaten the Gibraltar–Britain convoy route. Dönitz intended to concentrate his power in a rough arc from West Africa to South America and the Caribbean. He hoped to maintain a presence in the western and central Atlantic, reduce losses and await new weapons and anti-detection devices. In this, he failed to "stem the tide of U-boat losses." A large portion of the 39 U-boats deployed on these operations were intercepted. From May 1943, one historian wrote "U-boats rash enough to close with an Atlantic convoy...were simply inviting destruction."

Dönitz's crews faced danger from the outset. The transit routes through the Bay of Biscay were heavily patrolled by aircraft. From May to December 1943, 25 U-boats were sunk by Coastal Command, more were sunk by the USAAF and Royal Navy—five and four respectively; with one shared by the navy and Coastal Command. To counter radar aircraft, Dönitz ordered his submarines to group together and merge their powerful anti-aircraft armament together while surfaced and recharging their batteries, after initially ordering the groups to remain surfaced throughout the journey and fight off aerial attackers with gunfire. The decision was to cost BdU heavy casualties. A group of U-boats were more likely to attract a radar contact, and Allied pilots soon learned to swarm their targets. Dönitz ordered his captains to traverse the Bay under the lee of the neutral Spanish coast, with a sharply rising coast which shielded U-boats from radar. After 4 August 1943, the number of destroyed U-boats fell from one every four days, to one every 27 until June 1944.

US hunter–killer groups extended their patrols to the central Atlantic in the summer. They sank 15 U-boats from June through to August 1943. A number of supply submarines were destroyed crippling the Germans' ability to conduct long range operations. At the end of the summer, practically all supply U-boats had been destroyed. In September 1943, Dönitz ordered his submarines back to the North Atlantic. U-boats were equipped with the G7es torpedo, an acoustic torpedo, which the grand admiral hoped would wrest the technological initiative back. The torpedo was the centrepiece to Dönitz's plan. Great faith was also placed in the installation of Wanze radar to detect aircraft. It was intended as a successor to the Metox radar detector. A number of his boats were later retrofitted with the submarine snorkel, permitting the submarine to stay submerged. Dönitz placed much faith in the Type XXI submarine. He accepted that the older submarines were obsolete now that Allied defences in the air were complete. He required a "true submarine", equipped with a snorkel to allow his crews to stay submerged, at least to snorkel-depth, and evade radar-equipped aircraft. Dönitz was pleased with the promised top speed of 18 knots.

That month, 21 boats fought a battle with two formations; Convoys ONS 18/ON 202. The battle was a failure. In October an attack on Convoy SC 143 failed, even with limited air support from the Luftwaffe. The battle with Convoys ONS 20/ON 206 in the same month was a comprehensive defeat. A fourth major battle, Convoy SL 138/MKS 28, developed in the last days of October and ended in another failure for Dönitz. The November battle around Convoy SL 139/MKS 30 ended in the repulse of 29 U-boats with the loss of only a single ship. Intelligence proved its worth. During the battles of convoys ONS 18/ON 202, Dönitz's admonitions to his commanders allowed the Allied intelligence services to uncover German tactical intentions. Dönitz had tried and failed to push his forces through lethal convoy defences. The hunter-killer groups were called in to hunt the remaining members of the wolfpacks, with predictable results. In mid-December 1943, Dönitz finally conceded not only the Atlantic, but the Gibraltar routes as well.

The hunter-killer and convoy escorts brought the wolfpack era to an end at the close of 1943. Dönitz resorted to sending out single submarines to the far reaches of the oceans in a bid to escape Allied naval power. In November 1943 he sent the last U-boat into the Gulf of Mexico just after the blackout restrictions were lifted. U-193 achieved one final success. The end of 1943 ended the attempt of the U-boat arm to achieve a strategic victory in the Atlantic. That left only the Arctic convoys to the Soviet Union. On Christmas Eve, this became the sole preserve of the U-boats after the dispatch of Scharnhorst at the Battle of the North Cape.

Dönitz's plan for 1944 was simply to survive and await the XXI and Type XXIII submarines. New radars were on the horizon and a direction finding antenna for Naxos was scheduled for use. Dönitz established a naval operations scientific staff to focus on more powerful centimetric radars. Production of submarines was streamlined. Parts for eight major sections were fabricated across 60 plants in Europe and assembled at Hamburg, Danzig and Bremen to ease the pressure of bombing and congestion at shipyards. The first of the new generation boats were expected by April 1944. Dönitz hoped for 33 per month by September. In early 1944, Dönitz opted to concentrate west of Ireland, at 15 and 17° west, in the hope convoys would come to them. Single boats were still sent to the Mediterranean and Indian Ocean. With 66 vessels at sea at any one time, and with 200 boats operational, the BdU was still a viable threat and he believed the force could achieve modest success. The U-boats were painfully slow, strategically, operationally and tactically. Crossing the Atlantic took up to a month compared to a week in 1942. Positioning west of Ireland could take several weeks submerged. In the first quarter of 1944, U-boats sank only three of the 3,360 ships that passed south of Ireland. In return 29 crews were lost.

A major concern to Dönitz was Operation Overlord, the long predicted landing in France, and what role the U-boat arm and surface forces could play in the defence. He was sensitive to a landing on the Bay of Biscay but retained boats there only for operational readiness. Dönitz ended reconnaissance operations in the region. In the BdU war diary he wrote of ending operations since "otherwise the strong enemy air activity will lead to high losses which would only be acceptable if an immediate landing on the Biscay coast were expected. As this is no longer considered an acute danger the boats will remain at readiness in the concrete shelters."

When the D-day landings took place on 6 June 1944, the U-boats were ordered into action with the awareness that the western flank of the invasion would be well protected at sea. Operational experience with the snorkel was too scant to devise instructions for its use. The narrow, shallow, waters of the English Channel provided few opportunities for charging the batteries. Dönitz feared the task was impossible. The Holzbein group based at Brest, sent 15 submarines into action against the Cherbourg peninsula landings part of a 36-strong flotilla. Only eight had snorkels. The seven non-snorkel boats were ordered to attack on the surface. The BdU war diary entry on 6 June 1944 states that "for those boats without schnorchel this means the last operation". Of the 15, only five got near to the invasion fleet. Five of the snorkel boats survived. In exchange for 10 U-boats with the survivors damaged, two frigates, four freighters, and one tank landing ship were sunk. 22 U-boats were sunk from 6 to 30 June 1944. On 5 July 1944, the Allied Operation Dredger permitted hunter-killer groups to roam the Western Approaches and Biscay making it a "no-go area" for U-boats. U-boat operations against Normandy landings were a fiasco. Dönitz and the high command had been ignorant of the true scale of the naval D-day effort. Dönitz claimed his men sank five escorts, 12 merchant ships and four landing craft for 20 submarines and 1,000 men, of whom 238 were rescued. Dönitz's claims underplayed German losses, which were, in fact, 41 submarines from 82 in France, a 50 per cent loss rate.

The collapse of the German front in Normandy left only the bases in German-occupied Norway nearest to the Atlantic. The newer boats were not forthcoming either. Ninety Type XXI and 31 Type XIII boats were built by the end of 1944. Sixty of the former and 23 of the latter were in service but none were operational. Dönitz was left with the old VIIs to carry the war into 1945. A large number had snorkels, which enabled them to surface only upon reaching port. Submerged, this meant no radio or Enigma communications and far fewer sightings for the Allied intelligence network to exploit. Dönitz ordered his submarines to British coastal waters with some success in November and December 1944, achieving 85,639 tons. Admiral Andrew Cunningham remarked of the strategy, "We are having a difficult time with the U-boats....the air are about 90 percent out of business and Asdic is failing us." The inshore waters impeded the use of Asdic, which became confused with wrecks, rocks, and tidal swirls. The new types could conceivably have capitalised on these developments but the war was nearly over. On 1 January 1945, Dönitz had 425 submarines; 144 operational. On 1 April 1945, it was 166 from 429. He threw into battle every available weapon as the German Reich collapsed. Dönitz supported the use of Human torpedoes; the Neger, Marder, Seehund and Biber were all used in suicide missions on his orders, perhaps inspired by the Japanese Kamikaze.

On 30 April 1945 Adolf Hitler committed suicide. Dönitz succeeded him as head of state. Admiral Hans-Georg von Friedeburg succeeded Dönitz as commander-in-chief of the Kriegsmarine. On 4 May 1945 the German surrender at Lüneburg Heath took place. Dönitz issued an order to all U-boats to cease combat operations and return to port or surrender to Allied naval vessels. The order was obeyed with a handful of notable exceptions—the Actions of 5–6 May 1945, and Actions of 7–8 May 1945 occurred after the surrender. Throughout Dönitz’s presidency, Reich Marshal Hermann Goering feared that Dönitz would create a corresponding rank of Reich Admiral. However, Dönitz informed Goering (whom he personally disliked) that he had no time for such foolishness and that the presidency made him supreme commander of the German armed forces anyway. The surrendered U-boats numbered into the hundreds and were destroyed in the postwar Operation Deadlight. The U-boat war finally came to an end on 9 May 1945, the date of the German Instrument of Surrender.

Dönitz admired Hitler and was vocal about the qualities he perceived in Hitler's leadership. In August 1943, he praised his foresightedness and confidence; "anyone who thinks he can do better than the Führer is stupid." Dönitz's relationship with Hitler strengthened through to the end of the war, particularly after the 20 July plot, for the naval staff officers were not involved; when news of it came there was indignation in the OKM. Even after the war, Dönitz said he could never have joined the conspirators. Dönitz tried to imbue Nazi ideas among his officers, though the indoctrination of the naval officer corps was not the brainchild of Dönitz, but rather a continuation of the Nazification of the navy begun under his predecessor Raeder. Naval officers were required to attend a five-day education course in Nazi ideology. Dönitz's loyalty to him and the cause was rewarded by Hitler, who, owing to Dönitz's leadership, never felt abandoned by the navy. In gratitude, Hitler appointed the navy's commander as his successor before he committed suicide.

Dönitz's influence on military matters was also evident. Hitler acted on Dönitz's advice in September 1944 to block the Gulf of Finland after Finland abandoned the Axis powers. Operation Tanne Ost was a poorly executed disaster. Dönitz shared Hitler's senseless strategic judgement—with the Courland Pocket on the verge of collapse, and the air and army forces requesting a withdrawal, the two men were preoccupied in planning an attack on an isolated island in the far north. Hitler's willingness to listen to the naval commander was based on his high opinion of the navy's usefulness at this time. It reinforced isolated coastal garrisons along the Baltic and evacuated thousands of German soldiers and civilians in order that they might continue to participate in the war effort into the spring of 1945.

Through 1944 and 1945, the Dönitz-initiated Operation Hannibal had the distinction of being the largest naval evacuation in history. The Baltic Fleet was presented with a mass of targets, the subsequent Soviet submarine Baltic Sea campaign in 1944 and Soviet naval Baltic Sea campaign in 1945 inflicted grievous losses during Hannibal. The most notable was the sinking of the MV Wilhelm Gustloff by a Soviet submarine. The liner had nearly 10,000 people on board. The evacuations continued after the surrender. From 3 to 9 May 1945, 81,000 of the 150,000 persons waiting on the Hel Peninsula were evacuated without loss. Albrecht Brandi, commander of the eastern Baltic, initiated a counter operation, the Gulf of Finland campaign, but failed to have an impact.

In the final days of the war, after Hitler had taken refuge in the Führerbunker beneath the Reich Chancellery garden in Berlin, Reichsmarschall Hermann Göring was considered the obvious successor to Hitler, followed by Reichsführer-SS Heinrich Himmler. Göring, however, infuriated Hitler by radioing him in Berlin asking for permission to assume leadership of the Reich. Himmler also tried to seize power by entering into negotiations with Count Bernadotte. On 28 April 1945, the BBC reported Himmler had offered surrender to the western Allies and that the offer had been declined.

From mid-April 1945, Dönitz and elements of what remained of the Reich government moved into the buildings of the Stadtheide Barracks in Plön. In his last will and testament, dated 29 April 1945, Hitler named Dönitz his successor as Staatsoberhaupt (Head of State), with the titles of Reichspräsident (President) and Supreme Commander of the Armed Forces. The same document named Propaganda Minister Joseph Goebbels as Head of Government with the title of Reichskanzler (Chancellor). Hitler would not name any successors to hold his titles of Führer or leader of the Nazi Party. Furthermore, Hitler declared both Göring and Himmler traitors and expelled them from the party. He committed suicide on 30 April.

On 1 May, the day after Hitler's own suicide, Goebbels committed suicide. Dönitz thus became the sole representative of the collapsing German Reich. On 2 May, the new government of the Reich fled to Flensburg-Mürwik; Dönitz remained there until his arrest on 23 May 1945. That night, 2 May, Dönitz made a nationwide radio address in which he announced Hitler's death and said the war would continue in the East "to save Germany from destruction by the advancing Bolshevik enemy."

Dönitz knew that Germany's position was untenable and the Wehrmacht was no longer capable of offering meaningful resistance. During his brief period in office, he devoted most of his effort to ensuring the loyalty of the German armed forces and trying to ensure German personnel would surrender to the British or Americans and not the Soviets. He feared vengeful Soviet reprisals, and hoped to strike a deal with the Western Allies. In the end, Dönitz's tactics were moderately successful, enabling about 1.8 million German soldiers to escape Soviet capture. As many as 2.2 million may have been evacuated.

On 4 May, Admiral Hans-Georg von Friedeburg, representing Dönitz, surrendered all German forces in the Netherlands, Denmark, and northwestern Germany to Field Marshal Bernard Montgomery at Lüneburg Heath southeast of Hamburg, signaling the end of World War II in northwestern Europe.

A day later, Dönitz sent Friedeburg to US General Dwight D. Eisenhower's headquarters in Rheims, France, to negotiate a surrender to the Allies. The Chief of Staff of OKW, Generaloberst (Colonel-General) Alfred Jodl, arrived a day later. Dönitz had instructed them to draw out the negotiations for as long as possible so that German troops and refugees could surrender to the Western powers, but when Eisenhower let it be known he would not tolerate their stalling, Dönitz authorized Jodl to sign the instrument of unconditional surrender at 1:30 on the morning of 7 May. Just over an hour later, Jodl signed the documents. The surrender documents included the phrase, "All forces under German control to cease active operations at 23:01 hours Central European Time on 8 May 1945." At Stalin's insistence, on 8 May, shortly before midnight, (Generalfeldmarschall) Wilhelm Keitel repeated the signing in Berlin at Marshal Georgy Zhukov's headquarters, with General Carl Spaatz of the USAAF present as Eisenhower's representative. At the time specified, World War II in Europe ended.

On 23 May, the Dönitz government was dissolved when Dönitz was arrested by an RAF Regiment task force. The Großadmiral's Kriegsmarine flag, which was removed from his headquarters, can be seen at the RAF Regiment Heritage Centre at RAF Honington. Generaloberst Jodl, Reichsminister Speer and other members were also handed over to troops of the Herefordshire Regiment at Flensburg. His ceremonial baton, awarded to him by Hitler, can be seen in the regimental museum of the Kings Shropshire Light Infantry in Shrewsbury Castle and his car pennant in the regimental museum of the Herefordshire Light Infantry.

Dönitz was a dedicated Nazi and a passionate supporter of Hitler, something he attempted to obscure after the war. Raeder described him as "a picture-book Nazi and confirmed anti-Semite". Several naval officers described him as "closely tied to Hitler and Nazi ideology." On occasion, he spoke of Hitler's humanity. His fervent pro-Hitler attitude led to him being known ironically as "Hitler Youth Quex", after the fictional hero of a Nazi novel and feature film. He refused to help Albert Speer stop the scorched earth policy dictated by Hitler and is also noted to have declared, "In comparison to Hitler we are all pipsqueaks. Anyone who believes he can do better than the Führer is stupid."

Dönitz contributed to the spread of Nazism within the Kriegsmarine. He insisted that officers share his political views and, as head of the Kriegsmarine, formally joined the Nazi Party on 1 February 1944, as member 9,664,999. He was awarded the Golden Party Badge for his loyalty to the party later that year. Dönitz's influence over naval officers contributed to none joining the attempts to kill Hitler.

From an ideological standpoint, Dönitz was anti-Marxist and antisemitic and believed that Germany needed to fight the "poison of Jewry". Several anti-Semitic statements by Dönitz are known. When Sweden closed its international waters to Germany, he blamed this action on their fear and dependence on "international Jewish capital." In August 1944, he declared, "I would rather eat dirt than see my grandchildren grow up in the filthy, poisonous atmosphere of Jewry."

His fellow officers noted he was under Hitler's influence, and closely wedded to Nazi ideology. On German Heroes' Day (12 March) of 1944, Dönitz declared that, without Adolf Hitler, Germany would be beset by "the poison of Jewry," and the country destroyed for lack of the "uncompromising ideology" of National Socialism:

    What would have become of our country today, if the Führer had not united us under National Socialism? Divided along party lines, beset with the spreading poison of Jewry and vulnerable to it, because we lacked the defense of our present uncompromising ideology, we would have long since succumbed under the burden of this war and delivered ourselves to the enemy who would have mercilessly destroyed us.

At the Nuremberg trials, Dönitz claimed the statement about the "poison of Jewry" was regarding "the endurance, the power to endure, of the people, as it was composed, could be better preserved than if there were Jewish elements in the nation." Later, during the Nuremberg trials, Dönitz claimed to know nothing about the extermination of Jews and declared that nobody among "my men thought about violence against Jews." Dönitz told Leon Goldensohn, an American psychiatrist at Nuremberg, "I never had any idea of the goings-on as far as Jews were concerned. Hitler said each man should take care of his business and mine was U-boats and the Navy." After the war, Dönitz tried to hide his knowledge of the Holocaust. He was present at the October 1943 Posen Conference where Himmler described the mass murder of Jews with the intent of making the audience complicit in this crime. It cannot be proven beyond doubt that he was present during Himmler's segment of the conference, which openly discussed the mass murder of European Jews.

Even after the Nuremberg Trials, with the crimes of the Nazi state well-known, Dönitz remained an antisemite. In April 1953, he told Speer that if it was the choice of the Americans and not the Jews, he would have been released.

Following the war, Dönitz was held as a prisoner of war by the Allies. He was indicted as a major war criminal at the Nuremberg Trials on three counts. One: conspiracy to commit crimes against peace, war crimes, and crimes against humanity. Two: planning, initiating, and waging wars of aggression. Three: crimes against the laws of war. Dönitz was found not guilty on count one of the indictment, but guilty on counts two and three.

During the trial, army psychologist Gustave Gilbert was allowed to examine Nazi leaders on trial for war crimes. Among other tests, a German version of the Wechsler–Bellevue IQ test was administered. Dönitz and Hermann Göring scored 138, which made them equally the third-highest among the Nazi leaders tested. Throughout the trial, Reich Marshal Hermann Goering claimed to be the senior Nazi among the defendants. As for the former Reich President, Dönitz preferred to let Goering have his way. “It will attract more attention to him” he said.

At the trial, Dönitz was charged with waging unrestricted submarine warfare against neutral shipping, permitting Hitler's Commando Order of 18 October 1942 to remain in full force when he became commander-in-chief of the Navy, and to that extent responsibility for that crime. His defence was that the order excluded men captured in naval warfare, and that the order had not been acted upon by any men under his command. Added to that was his knowledge of 12,000 involuntary foreign workers working in the shipyards, and doing nothing to stop it. Dönitz was unable to defend himself on this charge convincingly when cross-examined by prosecutor Sir David Maxwell Fyfe.

On 25 February 1945, Hitler asked Dönitz whether the Geneva Convention should be denounced. Hitler's motives were twofold. The first was that reprisals could be taken against Western Allied prisoners of war; second, it would deter German forces from surrendering to the Western Allies, as was happening on the Eastern Front where the convention was in abeyance. Instead of arguing the conventions should never be denounced, Dönitz suggested it was not expedient to do so, so the court found against him on this issue; but as the convention was not denounced by Germany, and British prisoners in camps under Dönitz's jurisdiction were treated strictly according to the Convention, the Court considered these mitigating circumstances.

Among the war-crimes charges, Dönitz was accused of waging unrestricted submarine warfare for issuing War Order No. 154 in 1939, and another similar order after the Laconia incident in 1942, not to rescue survivors from ships attacked by submarine. By issuing these two orders, he was found guilty of causing Germany to be in breach of the Second London Naval Treaty of 1936. However, as evidence of similar conduct by the Allies was presented at his trial, his sentence was not assessed on the grounds of this breach of international law.

On the specific war crimes charge of ordering unrestricted submarine warfare, Dönitz was found "[not] guilty for his conduct of submarine warfare against British armed merchant ships", because they were often armed and equipped with radios which they used to notify the admiralty of attack. As stated by the judges:

    Dönitz is charged with waging unrestricted submarine warfare contrary to the Naval Protocol of 1936 to which Germany acceded, and which reaffirmed the rules of submarine warfare laid down in the London Naval Agreement of 1930 ... The order of Dönitz to sink neutral ships without warning when found within these zones was, therefore, in the opinion of the Tribunal, violation of the Protocol ... The orders, then, prove Dönitz is guilty of a violation of the Protocol ... The sentence of Dönitz is not assessed on the ground of his breaches of the international law of submarine warfare.

His sentence on unrestricted submarine warfare was not assessed because of similar actions by the Allies. In particular, the British Admiralty, on 8 May 1940, had ordered all vessels in the Skagerrak sunk on sight, and Admiral Chester Nimitz, wartime commander-in-chief of the US Pacific Fleet, stated the US Navy had waged unrestricted submarine warfare in the Pacific from the day the US officially entered the war. Thus, Dönitz was not charged of waging unrestricted submarine warfare against unarmed neutral shipping by ordering all ships in designated areas in international waters to be sunk without warning.

Dönitz was imprisoned for 10 years in Spandau Prison in what was then West Berlin. During his period in prison he was unrepentant, and maintained that he had done nothing wrong. He also rejected Speer's attempts to persuade him to end his devotion to Hitler and accept responsibility for the wrongs the German Government had committed. Conversely, over 100 senior Allied officers sent letters to Dönitz conveying their disappointment over the unfairness and verdict of his trial.

Dönitz was released on 1 October 1956 and retired to the small village of Aumühle in Schleswig-Holstein in northern West Germany. There, he worked on two books. His memoirs, Zehn Jahre, Zwanzig Tage (Memoirs: Ten Years and Twenty Days), were released in Germany in 1958 and became available in an English translation the following year. This book recounted Dönitz's experiences as U-boat commander (10 years) and President of Germany (20 days). In it, Dönitz explains the Nazi regime as a product of its time, but argues he was not a politician and thus not morally responsible for many of the regime's crimes. He likewise criticizes dictatorship as a fundamentally flawed form of government and blames it for many of the Nazi era's failings. Historian Alan P. Rems has written that Dönitz's memoirs are unconvincing and that "unimpeded by a meaningful Nuremberg verdict, Dönitz fashioned a legend that could be embraced by the most unregenerate Nazis as well as credulous Allied officers who accepted his sanitized version of history and showered Dönitz with letters of support as a wronged brother-in-arms".

Dönitz's second book, Mein wechselvolles Leben (My Ever-Changing Life) is less known, perhaps because it deals with the events of his life before 1934. This book was first published in 1968, and a new edition was released in 1998 with the revised title Mein soldatisches Leben (My Martial Life). In 1973, he appeared in the Thames Television production The World at War, in one of his few television appearances.

Dönitz was unrepentant regarding his role in World War II, saying that he had acted at all times out of duty to his nation. In 1976, Dönitz appeared in The Memory of Justice. In the documentary, Dönitz explains about the Nuremberg Trials and his experience during the trials in 1946 along with Albert Speer. He lived out the rest of his life in relative obscurity in Aumühle, occasionally corresponding with collectors of German naval history. Around 1974, Dönitz was contacted by Neo-Nazi conspiracy theorist and early Reichsbürger Manfred Roeder who tried to prove that the German Reich still existed. Roeder assumed that Dönitz remained the legal head of state, but the former admiral considered the idea ridiculous and firmly stated that he no longer considered himself President of Germany. Regarding this as a resignation declaration, Roeder subsequently declared himself the new leader of Germany and eventually became active as a terrorist.

Dönitz died in Aumühle of a heart attack on Christmas Eve 1980 at the age of 89. As the last German officer with the rank of Großadmiral (grand admiral), he was honoured by many former servicemen and foreign naval officers who came to pay their respects at his funeral on 6 January 1981. He was buried in Waldfriedhof Cemetery in Aumühle without military honours, and service members were not allowed to wear uniforms to the funeral. Also in attendance were over 100 holders of the Knight's Cross of the Iron Cross.

Bio of Stuka Ace Hans-Ulrich Rudel

Hans-Ulrich Rudel was born on 2 July 1916, in Konradswaldau, in Lower Silesia, Prussia. He was the third child of Lutheran minister Johannes Rudel. As a boy, Rudel was a poor scholar but a keen sportsman. Rudel attended the humanities oriented Gymnasium, in Lauban. He joined the Hitler Youth in 1933. After graduating with Abitur in 1936, he participated in the compulsory Reich Labour Service (RAD). Following the labour service, Rudel joined the Luftwaffe in the same year and began his military career as an air reconnaissance pilot.

German forces invaded Poland in 1939 starting World War II in Europe. As an air observer, Rudel flew on long-range reconnaissance missions over Poland. During 1940, he served as a regimental adjutant for the 43rd Aviators Training Regiment, based at Vienna.

In early 1941, he underwent training as a Stuka pilot. He was posted to 1st Staffel of Sturzkampfgeschwader 2 (StG 2), which was moved to occupied Poland in preparation for Operation Barbarossa, the invasion of the Soviet Union, in June 1941. On 21 September 1941, Rudel took part in an attack on the Soviet battleship Marat of the Baltic Fleet. Marat was sunk at her moorings on 23 September 1941 after being hit by one 1,000-kilogram (2,200 lb) bomb near the forward superstructure. It caused the explosion of the forward magazine which demolished the superstructure and the forward part of the hull. 326 men were killed and the ship gradually settled to the bottom in 11 meters (36 ft) of water. Her sinking is commonly credited to Rudel alone, but Rudel dropped only one of the two bombs that sank her. Rudel's unit then took part in Operation Typhoon, Army Group Center's attempt to capture the Soviet capital.

Rudel's gunner from October 1941 was Erwin Hentschel, who served with Rudel for the next two and a half years, both men earning the Knight's Cross of the Iron Cross during that period. Hentschel completed 1,400 sorties with Rudel and drowned on 21 March 1944 when they were making their way to the German lines following a forced landing.

In early 1942, Rudel got married while home on leave. Later in the year, he took part in the Battle of Stalingrad. From May 1941 to January 1942, Rudel flew 500 missions. In February 1943, Rudel flew his 1,000th combat mission, which made him into a national hero. He then participated in the experiments with using the Ju 87 G in the anti-tank role. The anti-tank unit took part in operations against the Soviet Kerch–Eltigen Operation. The footage from an onboard gun camera was used in Die Deutsche Wochenschau, a Reich Ministry of Propaganda newsreel. In April 1943, Rudel was awarded the Knight's Cross of the Iron Cross with Oak Leaves, receiving the Oak Leaves from Hitler personally in Berlin. Rudel participated in the Battle of Kursk with the same unit. On 12 July 1943 Rudel claimed 12 Soviet tanks in one day. In October 1943, Rudel was credited with the destruction of his 100th tank and was awarded the Knight's Cross of the Iron Cross with Oak Leaves and Swords (one of only 160 awarded) on 25 November.

Rudel was appointed Gruppenkommandeur of III. Gruppe on 22 February 1944. On 20 March, Rudel performed a forced landing behind Soviet lines and he and Hentschel (his gunner, mentioned above) escaped to the German lines. The men attempted to swim across the Dniester River but Hentschel drowned in the attempt. Upon his return, Ernst Gadermann, previously the troop doctor of III. Gruppe, joined Rudel as his new radio operator and air gunner. Rudel was awarded the Knight's Cross of the Iron Cross with Oak Leaves, Swords and Diamonds (one of only 27 awarded) on 29 March 1944, the tenth member of the Wehrmacht to receive this award. The presentation was made by Hitler personally.

Rudel was promoted to Oberstleutnant on 1 September 1944, and appointed leader of SG 2, replacing Stepp, on 1 October 1944. On 22 December 1944, Rudel completed his 2,400th combat mission, and the next day, he reported his 463rd tank destroyed. On 29 December 1944, Rudel was promoted to Oberst (colonel), and was awarded the Knight's Cross of the Iron Cross with Golden Oak Leaves, Swords, and Diamonds, the only person to receive this decoration. This award, intended as one of 12 to be given as a post-war victory award for Nazi Germany, was presented to him by Hitler on 1 January 1945, four months before Nazi Germany was defeated.

On 8 February 1945, Rudel was badly wounded in the right foot, and landed inside German lines as his radio operator shouted flight instructions. Rudel's leg was amputated below the knee. He returned to flying on 25 March 1945. He claimed 26 more tanks destroyed by the end of the war. On 19 April 1945, the day before Hitler's final birthday, Rudel met with Hitler in the Führerbunker at the Reich Chancellery in Berlin. On 8 May 1945, Rudel fled westward from an airfield near Prague, landing in US controlled territory, and surrendered. The Americans refused to hand him over to the Soviet Union.

While Rudel had been interned, his family fled from the advancing Red Army and had found refuge with Gadermann's parents in Wuppertal. Rudel was released in April 1946 and went into private business. In 1948, he emigrated to Argentina via the ratlines, travelling via the Austrian Zillertal to Italy. In Rome, with the help of South Tyrolean smugglers, and aided by the Austrian bishop Alois Hudal, he bought himself a fake Red Cross passport with the cover name "Emilio Meier", and took a flight from Rome to Buenos Aires, where he arrived on 8 June 1948. Rudel authored books on the war, supporting the regime and attacking the Oberkommando der Wehrmacht for "failing Hitler".

After Rudel moved to Argentina, he became a close friend and confidant of the President of Argentina Juan Perón, and Paraguay's dictator Alfredo Stroessner. In Argentina, he founded the "Kameradenwerk" (lit. "comrades' agency"), a relief organization for Nazi war criminals. Prominent members of the "Kameradenwerk" included SS officer Ludwig Lienhardt, whose extradition from Sweden had been demanded by the Soviet Union on war crime charges, Kurt Christmann, a member of the Gestapo sentenced to 10 years for war crimes committed at Krasnodar, Austrian war criminal Fridolin Guth, and the German spy in Chile, August Siebrecht. The group maintained close contact with other internationally wanted fascists, such as Ante Pavelić and Carlo Scorza. In addition to these war criminals that fled to Argentina, the "Kameradenwerk" also assisted Nazi criminals imprisoned in Europe, including Rudolf Hess and Karl Dönitz, with food parcels from Argentina and sometimes by paying their legal fees. In Argentina, Rudel became acquainted with notorious Nazi concentration camp doctor and war criminal Josef Mengele. Rudel, together with Willem Sassen, a former Waffen-SS and war correspondent for the Wehrmacht, who initially worked as Rudel's driver, helped to relocate Mengele to Brazil by introducing him to Nazi supporter Wolfgang Gerhard. In 1957, Rudel and Mengele together travelled to Chile to meet with Walter Rauff, the inventor of the mobile gas chamber.

In Argentina, Rudel lived in Villa Carlos Paz, roughly 36 kilometers (22 mi) from the populous Córdoba City, where he rented a house and operated a brickworks. There, Rudel wrote his wartime memoirs Trotzdem ("Nevertheless" or "In Spite of Everything"). The book was published in November 1949 by the Dürer-Verlag in Buenos Aires. Dürer-Verlag (1947–1958) issued a variety of apologia by former Nazis and their collaborators. Besides Rudel, among the early editors were Wilfred von Oven, the personal Press adjutant of Goebbels, and Naumann. Sassen convinced Adolf Eichmann to share his view on The Holocaust. Together with Eberhard Fritsch, a former Hitler Youth leader, Sassen began interviewing Eichmann in 1956 with the intent of publishing his views. The Dürer-Verlag went bankrupt in 1958.

Discussion ensued in West Germany on Rudel being allowed to publish the book, because he was a known Nazi. In the book, he supported Nazi policies. This book was later re-edited and published in the United States, as the Cold War intensified, under the title, Stuka Pilot, which supported the German invasion of the Soviet Union. Pierre Clostermann, a French fighter pilot, had befriended Rudel and wrote the foreword to the French edition of his book Stuka Pilot. In 1951, he published a pamphlet Dolchstoß oder Legende? ("Stab in the Back or Legend?"), in which he claimed that "Germany's war against the Soviet Union was a defensive war", moreover, "a crusade for the whole world". In the 1950s, Rudel befriended Savitri Devi, a writer and proponent of Hinduism and Nazism, and introduced her to a number of Nazi fugitives in Spain and the Middle East.

With the help of Perón, Rudel secured lucrative contracts with the Brazilian military. He was also active as a military adviser and arms dealer for the Bolivian regime, Augusto Pinochet in Chile and Stroessner in Paraguay. He was in contact with Werner Naumann, formerly a State Secretary in Goebbels' Ministry of Public Enlightenment and Propaganda in Nazi Germany. Following the Revolución Libertadora in 1955, a military and civilian uprising that ended the second presidential term of Perón, Rudel was forced to leave Argentina and move to Paraguay. During the following years in South America, Rudel frequently acted as a foreign representative for several German companies, including Salzgitter AG, Dornier Flugzeugwerke, Focke-Wulf, Messerschmitt, Siemens and Lahmeyer International, a German consulting engineering firm.

According to the historian Peter Hammerschmidt, based on files of the German Federal Intelligence Service and the US Central Intelligence Agency (CIA), the BND, under the cover-up company "Merex", was in close contact with former SS and Nazi Party members. In 1966, Merex, represented by Walter Drück, a former Generalmajor in the Wehrmacht and BND agent, helped by the contacts established by Rudel and Sassen, sold discarded equipment of the Bundeswehr (German Federal armed forces) to various dictators in Latin America. According to Hammerschmidt, Rudel assisted in establishing contact between Merex and Friedrich Schwend, a former member of the Reich Security Main Office and involved in Operation Bernhard. Schwend, according to Hammerschmidt, had close links with the military services of Peru and Bolivia. In the early sixties, Rudel, Schwend and Klaus Barbie, founded a company called "La Estrella", the star, which employed a number of former SS officers who had fled to Latin America. Rudel, through La Estrella, was also in contact with Otto Skorzeny, who had his own network of former SS and Wehrmacht officers.

Rudel returned to West Germany in 1953 and became a leading member of the Neo-Nazi nationalist political party, the German Reich Party (Deutsche Reichspartei or DRP). In the West German federal election of 1953, Rudel was the top candidate for the DRP, but was not elected to the Bundestag. According to Josef Müller-Marein, editor-in-chief of Die Zeit, Rudel had an egocentric character. In his political speeches, Rudel made generalizing statements, claiming that he was speaking on behalf of most, if not all, former German soldiers of World War II. Rudel heavily criticized the Western Allies during World War II for not having supported Germany in its war against the Soviet Union. Rudel's political demeanor subsequently alienated him from his former comrades, foremost Gadermann. Müller-Marein concluded his article with the statement: "Rudel no longer has a Geschwader (squadron)!" In 1977, he became a spokesman for the German People's Union, a nationalist political party founded by Gerhard Frey.

In October 1976, Rudel inadvertently triggered a chain of events, which were later dubbed the Rudel Scandal (Rudel-Affäre). The German 51st Reconnaissance Wing, the latest unit to hold the name "Immelmann", held a reunion for members of the unit, including those from World War II. The Secretary of State in the Federal Ministry of Defence, Hermann Schmidt authorized the event. Fearing that Rudel would spread Nazi propaganda on the German Air Force airbase in Bremgarten near Freiburg, Schmidt ordered that the meeting could not be held at the airbase. News of this decision reached Generalleutnant Walter Krupinski, at the time commanding general of NATO's Second Allied Tactical Air Force, and a former World War II fighter pilot. Krupinski contacted Gerhard Limberg, Inspector of the Air Force, requesting that the meeting be allowed at the airbase. Limberg later confirmed Krupinski's request, and the meeting was held on Bundeswehr premises, a decision to which Schmidt still had not agreed. Rudel attended the meeting, at which he signed his book and gave a few autographs but refrained from making any political statements.

During a routine press event, journalists who had been briefed by Schmidt questioned Krupinski and his deputy Karl Heinz Franke about Rudel's presence. In this interview, the generals compared Rudel's past as a Nazi and Neo-Nazi supporter to the career of prominent Social Democrat leader Herbert Wehner, who had been a member of the German Communist Party in the 1930s, and who had lived in Moscow during World War II, where he was allegedly involved in NKVD operations. Calling Wehner an extremist, they described Rudel as an honorable man, who "hadn't stolen the family silver or anything else". When these remarks became public, the Federal Minister of Defense Georg Leber, complying with §50 of the Soldatengesetz (Military law), ordered the generals into early retirement as of 1 November 1976. Leber, a member of the Social Democratic Party of Germany (SPD), was heavily criticized for his actions by the Christian Democratic Union (CDU) opposition, and the scandal contributed to the minister's subsequent retirement in early 1978. On 3 February 1977, the German Bundestag debated the scandal and its consequences. The Rudel Scandal subsequently triggered a military-tradition discussion, which the Federal Minister of Defense Hans Apel ended with the introduction of "Guidelines for Understanding and Cultivating Tradition" on 20 September 1982.

During the 1978 World Cup, held in Argentina, Rudel visited the German national football team in its training camp in Ascochinga. The German media criticized the German Football Association, and viewed Rudel's visit as being sympathetic to the military dictatorship that ruled Argentina following the 1976 Argentine coup d'état. During the 1958 FIFA World Cup in Sweden, he visited the German team at Malmö on 8 June 1958. There he was welcomed by team manager Sepp Herberger.

Rudel was married three times. His 1942 marriage to Ursula Bergmann, nicknamed "Hanne", produced two sons, Hans-Ulrich and Siegfried. They divorced in 1950. According to the news magazine Der Spiegel, one reason for the divorce was that his wife had sold some of his decorations, including the Oak Leaves with Diamonds, to an American collector, but she also refused to move to Argentina. On 27 March 1951, Der Spiegel published Ursula Rudel's denial of selling his decorations, and further stated she had no intention of doing so. Rudel married his second wife, Ursula née Daemisch, in 1965. The marriage produced his third son, Christoph, born in 1969. Rudel survived a stroke on 26 April 1970. Following his divorce in 1977, he married Ursula née Bassfeld.

Rudel died following another stroke in Rosenheim on 18 December 1982, and was buried in Dornhausen on 22 December 1982. During Rudel's burial ceremony, two Bundeswehr F-4 Phantoms appeared to make a low altitude flypast over his grave. Dornhausen was situated in the middle of a flightpath regularly flown by military aircraft, and Bundeswehr officers denied deliberately flying aircraft over the funeral. Four mourners were photographed giving Nazi salutes at the funeral, and were investigated under a law banning the display of Nazi symbols. The Federal Minister of Defence Manfred Wörner declared that the flight of the aircraft had been a normal training exercise.

Rudel flew 2,530 combat missions on the Eastern Front of World War II. The majority of these were undertaken while flying the Junkers Ju 87, although 430 were flown in ground-attack variants of the Focke-Wulf Fw 190. He was credited with the destruction of 519 tanks, severely damaging the battleship Marat, as well as sinking a cruiser (incomplete and heavily damaged Petropavlovsk), a destroyer (the Leningrad-class destroyer Minsk) and 70 landing craft. Rudel also claimed to have destroyed more than 800 vehicles of all types, over 150 artillery, anti-tank or anti-aircraft positions, 4 armored trains, as well as numerous bridges and supply lines. Rudel was also credited with 9 aerial victories, 7 of which were fighter aircraft and 2 Ilyushin Il-2s. He was shot down or forced to land 30 times due to anti-aircraft artillery, was wounded five times and rescued six stranded aircrew from enemy-held territory.

Rudel remained popular with the German far-right after his death, especially with the German People's Union, the DVU, and its leader Gerhard Frey. Frey and the DVU established the Ehrenbund Rudel – Gemeinschaft zum Schutz der Frontsoldaten (Honour federation Rudel – Community for the protection of the front soldiers) in 1983 during a memorial service for Rudel. British holocaust denier David Irving was given the Hans-Ulrich Rudel Award by Frey in June 1985; he delivered a memorial speech on the death of Rudel.
