Attacks on U-553 during this patrol
17 Oct 1941
After a successful attack on convoy SC 48, the boat dived to 90m (295ft) to avoid a destroyer which approached. Three depth charges were dropped at the diving position, detonating high above the U-boat which escaped further attacks by passing under the convoy. The destroyer was probably USS Kearny, which dropped a single depth charge at 00.22 hrs. (Sources: KTB U-553/ADM 237-164)
