Despite being shelled by an armed freighter, U-101 completed the launch of torpedoes in a final attack on convoy SC 7 north of Ireland. The shells missed, landing astern as U-101 was turning away and zig-zagging. (Sources: Ritschel)
29 Jan 1941
04.16 hrs, North Atlantic west of Ireland: gunfire from a destroyer forced U-101 to dive as she was attempting to attack convoy SC 19. Three depth charges launched subsequently caused no damage. (Sources: Ritschel)
