U-570

Shown here is the Type VIIC boat U-570 after surrendering to the British. U-570 left Trondheim on 23 August 1941 for its first war cruise, under the command of Kapitanleutnant Hans Joachim Rahmlow. Four days later, when south of Iceland, it was spotted by a Hudson of No.269 Sqd, flown by Sergeant Mitchell from Kaldadarnes, who attacked but his depth charges failed to release. The crew called in another Hudson on patrol, flown by Suadron Leader J.H. Thompson, who dropped depth charges and began machine-gunning the deck of the U-boat when it surfaced. Then the RAF men were surprised to see a white flag flying from the conning tower and the crew gathering on deck. Unknown to them, chlorine gas had escaped from the hull of the U-boat. The Hudson signalled for help and remained on station until Catalina (AH553) of No.209 Sqd, flown by Flying officer E.A Jewiss, arrived abour three hours later from Reykjavik. Ref: AIR 27/1568
