Thanks, it answered my question about why we were depending on refurbished fishing trawlers.
Also, fascinated by this in the Wiki article:
“The first sinking of a U-boat by a U.S. Navy ship off the coast of the U.S. did not occur until April 14, 1942, when the destroyer USS Roper sank the U-85. It has come to light in recent years that the famous “Loose Lips Sink Ships” propaganda campaign in the U.S. that started in 1942 was not so much designed to deny German agents knowledge of vessels’ sailing times (there were no such agents anyway) but rather to keep American civilian morale high by reducing communication about how much shipping was being sunk during Operation Drumbeat.”
Can you imagine the gov’t getting away with that today?
