1941

U-67. The boat was depth charged by the British corvette HMS Bluebell. This attack was thought to have sunk U-208 but instead slightly damaged U-67. (FDS/NHB)

U-652. At 1439 hours (Berlin time), while west of Ustica Island in position 38.42N, 12.51E, the Dutch submarine HrMs O 24 (Lt.Cdr. O. de Booy, RNN) fired three torpedoes at a German U-boat. A full bow salvo of four torpedoes was intended but the enemy changes course after the third torpedo had been fired which then all missed. The fourth bow torpedo was not fired. According to the German log U-652 spotted the periscope of the attacker and course was changed. Shortly afterwards two torpedo tracks were sighted.

No U-boats were lost on this date, 11 December.
