Forextraordinaryheriosm as a platoon commander in Company M, Third Battalion, Seventh Marines, in Quang Nam Province, Republic of Vietnam, on 6 November 1968. The company advance in a sweep operation south of Hill 55 where it encountered a large North Vietnamese Army force and sustained heavy casualties at the first bitter engagement. The well entrenched enemy kept the company pinned down with rocket propelled grenades and heavy small-arms and automatic-weapons fire, making evacuation of casualties a hazardous chore. As the company pressed the attack, the wounded and dead were moved toward the rear where Second Lieutenant Sleigh was directing the establishment of a landing zone. Taking charge of the critical situation, Second Lieutenant Sleigh strategically deployed his men to return suppressive fire and at the same time maintained control of the evacuation. Two helicopter landings were attempted, and on the second effort a rocket propelled grenade landed near the wounded who were being treated. Observing the danger to the wounded, Second Lieutenant Sleigh crawled to one casualty and lay huddled over him as a shield when another rocket propelled grenade landed less than a meter away, instantly killing Second Lieutenant Sleigh. He thus absorbed most of the shock with his body, not only saving the life of one Marine, but also preventing injury to others near him. His valiant leadership and courageous fighting spirit inspired all the men of the company who observed his last brave act. Second Lieutenant Sleigh’s heroism reflected great credit upon himself and the Marine Corps and upheld the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
