1943 - On 13 August John Penn had just finished unloading a cargo of 155-mm. ammunition off Lunga Point, Guadalcanal. At 2120 she came under attack by enemy torpedo planes. Three minutes later, when the transport took one of the planes under fire, it burst into flames and crashed into her mainmast. About that same instant a torpedo hit from another plane hit the ship. Although vigorous efforts were made to save her, John Penn went down stern first at 2150.
