WIth Woody Guthrie and Cisco Houston having survived at least one sinking, I have to believe that somewhere in the Guthrie archives there are some convoy songs.
I had to inteview a former officer of a Canadian corvette about something that had nothing to do with the war but the subject of his wartime service had come up. I was so taken with his convoy escort stories that I gave him a copy of "Convoy: the battle for convoys SC.122 and HX.229 by Martin Middlebrook whch I had recently read. He later told me that it was a very accurate book with lots of insights on life at sea during that time.
It is a very readable, with lots of insights into the strategies of that part of the war. It was far more complex than I had imagined and always fascinating. (it is out of print but available through Amazon in paperback)
