Battle of Kolombangara
On 13 July 1943 during the Battle of Kolombangara, "Gwin" was turning with formation to bring all main batteries to bear on four enemy destroyers, when the Japanese ships released a salvo of over 30 torpedoes at the Americans. At approximately 0210 three US ships were hit, including "Gwin" which was hit amidships by a torpedo in her engine room. When damage control efforts failed, the ship was abandoned and was scuttled by Ralph Talbot (DD-390), with a loss of 61 men.
