How many of us are so paranoid that we zig-zag submerged to avoid detection?

Thanks, Kielhauler, for expanding my knowledge base. I was unaware of this action and have corrected my earlier post. Three points: First, the action took place very late in the war, with much-refined equipment. Second, U-864 was running submerged on Diesels with a schnorkel, and had a noisy defective engine to boot, making her a much stronger acoustic source. Finally, while a German sub was involved, it was on the receiving end.
Still this is the only successful hydrophone-only attack ever officially acknowledged. Very impressive!
