Find the book,"Torpedoes In The Gulf." Pam..I forgot the author and would take me a week to find. The U-Boats 1st hit the east coast and it was like shooting fish in a barrel for months. Then when the naval authorities finally got wise and blacked out the lights on the coastal cities and convoyed the U-Boats moved to the gulf for a repeat. The U-Boat captains and crews called it the,"Good Times."
