"Royal Air Force 1939-1945- Coastal Command" On 27 August 1941 Coastal Command claimed a rare and unusual success when one of its aircraft was instrumental in the capture of a U-boat. A No 269 Squadron Hudson operating from Kaldadarnes in Iceland, flown by Squadron leader J. H. Thompson, surprised U-570 on the surface. Thomson dropped a stick of depth charges, after which the German crew was seen spilling out onto the casing, waving white flags. This photograph was taken later by a Catalina from No 209 Squadron, called to the scene along with various Royal Navy vessels. Heavy seas at first prevented a boarding party from reaching the U-boat, but eventually they were able to accept the crew's surrender.
