for temporary repairs, and on 19 April departed Okinawa. After escorting the aircraft carrier Intrepid (CV-11) to Pearl Harbor, she sailed for San Diego, reaching there 18 May for battle repairs. While Gregory was still in overhaul, the Japanese surrendered and the destroyer was placed in inactive status, in commission in reserve, at San Diego. She decommissioned 15 January 1947. 1951 – 1964 Gregory’s rest was to be brief, as Communist forces launched their war in Korea 24 June 1950 and the U.S. Navy joined United Nations forces; she recommissioned 27 April 1951. Reaching Yokosuka, Japan, via Pearl Harbor and Midway 16 August 1951, Gregory immediately began patrol duty along the Korean coast. Her principal duties were screening American carriers, such as Essex (CV-9) and Boxer (CV-21), from which air strikes against North Korean positions and supply lines were launched; blockading the coast, and participating in coastal bombardment as the tide of war ebbed and flowed along the Korean peninsula. In addition, she was frequently assigned to the Formosa patrol, intended to prevent Communist action against the beleaguered republic. Here Gregory came under fire from mainland Communist Chinese shore batteries. While on a search-and-rescue (SAR) mission for a downed P2V 19 January 1953, she closed to within 8,000 yards of Nan-ao Tao, an island just off the China coast that had fallen to the Communists on 3 March 1950 in the Battle of Nan'ao Island. Though shore batteries opened fire on her. Gregory did not return fire, instead clearing the area immediately to continue her SAR mission. After the Korean Armistice ended the shooting war in August 1953, Gregory returned to a peacetime routine of local operations out of San Diego interspersed with yearly deployments, usually 6 months long, to the Far East. These deployments took her to Yokosuka, Sasebo, Hong Kong, Bangkok, Sydney, Okinawa, the Philippines, and Formosa for training maneuvers with American and other warships. In the fall of 1958 Gregory spent a tension-filled 2½ months off the China coast during one of the periodic intensification of the Quemoy-Matsu crisis. Gregory earned the Battle Efficiency "E" three times during her post-war career — 1955, 1956, and 1959. Gregory was decommissioned at San Diego, Calif. on 1 February 1964 and entered the reserve. She was struck from the Navy List 1 May 1966, renamed Indoctrinator, and served as an inoperable trainer at San Diego from 20 May 1966 to
