Alexander, Harley Edwin, COX

Approaching her gunfire support station at 08:30, 8 June, USS Glennon (DD-620) stern struck a mine. A whaleboat picked up survivors while minesweepers Staff and Threat arrived on the scene, one passing a towline while the other swept ahead of the damaged destroyer. 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 9 June, salvage equipment was assembled, and some 60 officers and men of Glennon came back on board. The following morning, just as Cdr. Johnson was preparing to resume efforts to save his ship, a German shore battery near Quineville found her range. A second salvo hit Glennon amidships and cut off all power. After a third hit, Cdr. Johnson ordered his crew to abandon ship and the men were taken off in a landing craft. Glennon floated until 21:45, 10 June 1944, then rolled over and sank. She suffered 25 lost and 38 wounded.

COX Alexander was among the men listed as missing in action and later declared dead.
