USS Glennon (DD-620) was a , the first ship of the United States Navy to be named for Rear Admiral James H. Glennon, who was a recipient of the Navy Cross. Service history Glennon was launched on 26 August 1942 by the Federal Shipbuilding & Dry Dock Company, of Kearny, New Jersey, sponsored by Miss Jeanne Lejeune Glennon (whose later surname was Hull), granddaughter of Admiral Glennon, and commissioned on 8 October 1942. Convoy duty and operations in the Mediterranean After shakedown training along the New England coast, Glennon guarded troops and supply convoys for the Allied invasion of Sicily, Italy. She was in action during the Amphibious Battle of Gela, fought from 9 to 15 July 1943. Glennon continued to operate in the Mediterranean Sea and returned to New York on 3 December 1943. The destroyer then made two round-trip convoy escort voyages to the British Isles and one to Gibraltar. She arrived in New York from Gibraltar on 22 April 1944, and stood out of that port on 5 May with a task group which arrived at Belfast, Northern Ireland, on the 14th. Invasion of Normandy and sinking Assigned to Assault Force "U" of the Western Naval Task Force, she arrived in the Baie de la Seine, France, on 6 June. After patrolling around the bombardment group for submarines and fast German torpedo boats, she joined in gunfire support of troops ashore. On 7 June, she fired 430 shells ashore in support of troops advancing north toward Quinéville. She was again approaching her gunfire support station at 08:30 on 8 June, when her stern struck a mine. A whaleboat picked up survivors while minesweepers and arrived on the scene, one passing a towline while the other swept ahead of the damaged destroyer. The destroyer escort closed in the wake of the minesweepers to assist, then felt a heavy explosion as she slowly rounded Glennons stern to clear the area. Minutes later a second explosion blew off a section of Richs stern, followed by a third mine explosion under her forecastle. Rich sank within 15 minutes of the first explosion. The minesweeper Staff found she could not budge Glennon, whose stern seemed to be firmly anchored to the bottom by her starboard propeller. Most of her crew boarded Staff, and those remaining on Glennon lightened her stern by pumping fuel forward and jettisoning depth charges and topside gear. On
