Another good book on WW2 submarine warfare, from the German perspective, is ‘Operation Drumbeat’ which focuses on German subs operating in or near U.S. waters during the early years of the war. In fact I’m sure since the sub mentioned was sunk off N. Carolina in 1942, it would have been part of that operation.
It was a mostly forgotten disaster for us. They called it a seagoing Stalingrad because of so many ships sunk and so much equipment lost.
My mom told us they went to the Jersey shore that summer and one night they went to the top of the hill in Long Branch to watch a ship burning offshore.
