My worst depth charging didn't come from escorts, but from aircraft...coming back from a patrol mid 1942 in a VIIc (U553) I was surprised in the Bay of Biscay and got hit by four wabos that knocked out my starboard engine, damaged the port to about 50%, killed several of the crew, reduced my hull integrity to 30% and caused a LOT of flooding that still I still am surprised I managed to make the repairs and slip into port. To add insuly to injury I was sunk next patrol by planes south of Iceland
