Bloodstained Sea is a history of the Coast Guard during World War II....Keep in mind that during wartime the Coast Guard is activated basically as an arm of the Navy, so this is a tale of hunting submarines and combat, as well as rescues at sea and patrols. It was published in 2004, so it is reasonably current, and at $1.99 the Kindle version is a steal compared to the paperback at $16.99!
