World War I From August 1917 to January 1918, Major Holcomb commanded the 2d Battalion, 6th Marine Regiment, at the Marine Barracks, Quantico, Virginia, in preparation for overseas duty.

In April 1941 the US Navy convened its General Board to discuss expansion of the Corps. Holcomb said that African Americans had no right to serve as Marines. He said, "If it were a question of having a Marine Corps of 5,000 whites or 250,000 Negroes, I would rather have the whites." In 1943, he passed Letter of Instruction 421, which restricted African-American Marines' ability to be promoted and prevented them from serving as non-commissioned officers in charge of whites.
With his advancement to lieutenant general on January 20, 1942, he became the highest-ranking officer ever to command the Marine Corps up to that time.
On August 5, 1943, when Lt Gen Holcomb reached the regular retirement age, President Franklin D. Roosevelt announced he was continuing LtGen Holcomb as Commandant of the Marine Corps, in recognition of his outstanding services in that capacity. Holcomb continued as commandant until December 31, 1943. He was succeeded by LtGen Alexander A. Vandegrift.
On April 12, 1944, Holcomb was awarded the Navy Distinguished Service Medal for his outstanding work as commandant.
Retirement from the Marine Corps After nearly 44 years as a Marine, LtGen Holcomb retired on January 1, 1944. Because he had been specially commended for his performance of duty in actual combat, he was advanced one rank on the retired list in accordance with a newly passed Act of Congress. He thus became the first Marine ever to hold the rank of general.
