Rank and organization:   Captain, U.S. Marine Corps, Company A, 1st Battalion, 9th Marines, 3d Marine Division.  Place and date:  Quang Tri Province, Republic of Vietnam, 22 February 1969. Entered service at:  Leesburg, Va.  Born:  30 September 1931, Herndon, Va. Citation:  For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving as commanding officer of Company A, in action against the enemy in the northern A Shau Valley.  Capt. (then 1st Lt.) Fox's company came under intense fire from a large well concealed enemy force. Capt. Fox maneuvered to a position from which he could assess the situation and confer with his platoon leaders.  As they departed to execute the plan he had devised, the enemy attacked and Capt. Fox was wounded along with all of the other members of the command group, except the executive officer.  Capt. Fox continued to direct the activity of his company.  Advancing through heavy enemy fire, he personally neutralized 1 enemy position and calmly ordered an assault against the hostile emplacements. He then moved through the hazardous area coordinating aircraft support with the activities of his men.  When his executive officer was mortally wounded, Capt. Fox reorganized the company and directed the fire of his men as they hurled grenades against the enemy and drove the hostile forces into retreat.  Wounded again in the final assault, Capt. Fox refused medical attention, established a defensive posture and supervised the preparation of casualties for medical evacuation. His indomitable courage, inspiring initiative, and unwavering devotion to duty in the face of grave personal danger inspired his marines to such aggressive action that they overcame all enemy resistance and destroyed a large bunker complex. Capt. Fox's heroic actions reflect great credit upon himself and the Marine Corps, and uphold the highest traditions of the U.S. Naval Service.
