The battle | On the end of October, the Germans become aware of an Allied build-up of forces around Gibraltar. As a reaction, the BdU forms a patrol line in the region. Several ships, merchants and escorts are detected on the 25th and 26th. On the 27th U-604 sinks an escorted tanker and U-409 sights the convoy. U-409 brings up U-203, U-509 and U-659 and they attack at night. Only U-509 has success, sinking 2 ships. U-203 keeps contact with the convoy on the 28th and brings up U-409, U-509, U-510, U-604 and U-659. U-103 and U-440 arrive as reinforcement. U-509 is after a successful night still in touch with the convoy. In the morning she has a miss, and in the evening she sinks and damages one ship. The damaged ship explodes but remains afloat until it is finished off by U-203 the next day. During night, none of the boats in contact manages to make an attack.U-134 is the contact keeper on the 29th and leads U-103, U-509, U-510 and U-604 to the convoy. The boats attack at night. U-409 damages one ship but again U-509 is very successful and sinks and damages 1 ship. Both damaged ships are later again torpedoed by U-659. One sinks and the other one is finally sunk with torpedo and gunfire by U-203. During next day, most of the boats are brought up by U-509 and U-604 and in the night U-604 sinks 2 ships, U-409 sinks one and U-659 and U-510 damage one each. U-659 is damaged by depth charges in an counterattack from the escorts. U-103 finishes off one damaged ship. On the 31th the air escort arrives and manages to drive off all U-boats. Two destroyers arrive from Gibraltar but are too late to see any action. The battle had lasted for 5 days and was very successful for the Germans. However this success had a bitter aftertaste as at the same time many more important convoys on their way for Operation Torch, the landings in North-Africa, were routed around the U-boat concentration and reached their destination unmolested. In this perspective the words of the SL-125 convoy commodore must be understood when he told after the war that 'This is the only time I have been congratulated for losing ships...' |
