Yikes lol . My most recent patrol in Narwhal, Feb 1944 off Palau, they put a pattern down, glad I had the cam off , it was bad inside, they were close. Don't recall boat shaking that way before and my topside was wrecked when surfaced, JP sonar head mounted on deck damaged beyond repair, etc. Forward deck and AA guns not functional, periscopes damage, real mess. I was at 370 ft.
