Eternal Patrol

During WWII a great deal of submarines left on the eternal patrol, never to return to port. Most of these submarines were lost with all hands. After the war, submarine losses ended, at least until 10 April 1963, when the USS Thresher went down and never came up. To this day, the Thresher is the last US submarine to have sunk - while major mishaps have happened on other submarines, resulting in decommissioning (notably the USS Bonefish), none of them sank. Let us all lift one in honor of all submarines that never came back to port, those brave souls on the eternal patrol.
