Rank and organization: Major General, U.S. Marine Corps, commanding officer of the 1st Marine Division. Place and date: Solomon Islands, 7 August to 9 December 1942. Entered service at: Virginia. Born: 13 March 1887, Charlottesville, Va. Citation: For outstanding and heroic accomplishment above and beyond the call of duty as commanding officer of the 1st Marine Division in operations against enemy Japanese forces in the Solomon Islands during the period 7 August to 9 December 1942. With the adverse factors of weather, terrain, and disease making his task a difficult and hazardous undertaking, and with his command eventually including sea, land, and air forces of Army, Navy, and Marine Corps, Maj. Gen. Vandegrift achieved marked success in commanding the initial landings of the U.S. forces in the Solomon Islands and in their subsequent occupation. His tenacity, courage, and resourcefulness prevailed against a strong, determined, and experienced enemy, and the gallant fighting spirit of the men under his inspiring leadership enabled them to withstand aerial, land, and sea bombardment, to surmount all obstacles, and leave a disorganized and ravaged enemy. This dangerous but vital mission, accomplished at the constant risk of his life, resulted in securing a valuable base for further operations of our forces against the enemy, and its successful completion reflects great credit upon Maj. Gen. Vandegrift, his command, and the U.S. Naval Service.
Leadership is action, not position.
