Photo above shows Type II boats approaching and tying up at the 21. U-Flottille’s base in Pillau. The submarine in the foreground is U-62. Under Oberleutnant zur See Hans-Bernhard Michalowski, the Type II C sank two ships during fire patrols in the period 1 February – 30 September 1940, including the British destroyer HMS Grafton. The latter vessel was taking part in “Operation Dynamo”, the evacuation of Allied troops from Dunkirk. During the night of 29 May 1940, while attempting to rescue survivors from HMS Wakeful, which had been sunk by the German motor torpedo boat S-30 a short time before, the destroyer was torpedoed by U-62 and sank. In October 1940 U-62 became a training vessel. Note the rescue buoy on the afterdeck and the training emblem on the conning tower. Approaching in the background is U-61, another Type II C.
