Perhaps this should be a new thread, but I added here instead because there is already so much info here (which I don't have time to read, unfortunately.)

This song was sung at Monday's Zoom song circle. My understanding of the discussion was that the U-Boat which sunk the Reuben James is the U-505 which was captured and now resides in the Chicago Museum of Science and Industry.

This isn't true.

The Reuben James was sunk by U-552.

According to Wikipedia, U-505 first patrol was in 1942. However, she was undergoing training exercises in 1941.

This article states that it was actually U-552 which sank the USS Reuben James.

I apologize if I misunderstood the discussion on Monday.
