With the fighting in central Poland winding down, Hitler presided over an 8. Armee victory parade in Warsaw, the recently captured enemy capital, on 5 October 1939. Although PzKpfw I Ausf.B, such as these, were ill-suited for direct combat, necessity often dictated otherwise; including the fight for Warsaw. Soon to gain fame commanding 7. Panzer-Division in the West, Generalmajor Erwin Rommel – a distant cousin of Lódź Army’s commander, Major General Juliusz Rómmel – stands with other high ranking officers below Hitler as head of the Führerbegleithauptquartier (Führer Escort Headquarters), having provided security for the event, while at the podium we can see, from left to right: Generaloberst Walther von Brauchitsch (Oberbefehlshaber des Heeres), Hitler, General der Kavallerie Maximilian Reichsfreiherr von Weichs (Kommandierender General XIII. Armeekorps), Generaloberst Walther von Reichenau (Oberbefehlshaber 10. Armee), and General der Flieger Alexander Löhr (Chef Luftflotte 4). Generaloberst Johannes Blaskowitz (Oberbefehlshaber 2. Armee) and General der Flieger Albert Kesselring (Chef Luftflotte 1) were blocked by the back of panzer commander at right. The picture was taken by Hugo Jaeger, one of Hitler's personal photographer
