A photo taken by Hermann Weper, an officer serving with Maschinengewehr-Bataillon 52, on 4 June 1940 following the seizure of Dunkirk: German forces arrive in Dunkirk. The sea front at Dunkirk photographed immediately after the completion of the evacuation of the British Expeditionary Force earlier in the day. The crew of a 20mm Flak 38 gun of the German mobile assault unit Motorensturm 13 stand guard on the seafront. The gun is covered with a camouflage shelter quarter. Debris left by the evacuating British forces is visible in the background.
