Attacks on U-333 during this patrol

6 Oct 1942
The boat fought an epic battle with the British corvette HMS Crocus off the coast of Sierra Leone, west Africa on 6 Oct. 1942. The U-boat lost three men (including the IWO) and several men were wounded, including the commander, Peter Erich Cremer. The boat was heavily damaged and limped back to base with the help of a replacement WO, Kptlt. Lorenz Kasch, from U-107. The doctor from the milch cow boat U-459 tended the wounded. Cremer then spent three months in hospital. [Oberleutnant zur See Bernhard Hermann, Bootsmaat Heinz Kurze, Maschinenobergefreiter Erwin Levermann].

21 Oct 1942
The former U-570 (captured 27 Aug. 1941) on her first patrol in British service as HMS Graph, commanded by Lt Cdr Peter Marriot, fired a spread of torpedoes at the heavily damaged inbound U-333 north of Cape Ferrol, Spain. Alert lookouts spotted the tracks and U-333 took successful evasive action. It only became apparent after the war that this attack was by the former U-boat. (Sources: Blair, vol 2, page 69)
