The Senior Marine Commanders
The four senior Marine commanders at Okinawa were seasoned combat veterans and well versed in joint service operations—qualities that enhanced Marine Corps contributions to the success of the U.S. Tenth Army.
MajGen Roy S. Geiger
Major General Roy S. Geiger, USMC, commanded III Amphibious Corps. Geiger was 60, a native of Middleburg, Florida, and a graduate of both Florida State Normal and Stetson University Law School. He enlisted in the Marines in 1907 and became a naval aviator (the fifth Marine to be so designated) in 1917. Geiger flew combat missions in France in World War I in command of a squadron of the Northern Bombing Group. At Guadalcanal in 1942 he commanded the 1st Marine Aircraft Wing, and in 1943 he assumed command of I Marine Amphibious Corps (later IIIAC) on Bougainville, and for the invasions of Guam, and the Palaus. Geiger had a nose for combat; even on Okinawa he conducted frequent visits to the front lines and combat outposts. On two occasions he “appropriated” an observation plane to fly over the battlefield for a personal reconnaissance. With the death of General Buckner, Geiger assumed command of the Tenth Army, a singular and fitting attainment, and was immediately promoted to lieutenant general by the Marine Corps. Geiger subsequently relieved General Holland M. Smith as Commanding General, Fleet Marine Force, Pacific. In that capacity, he was one of the very few Marines invited to attend the Japanese surrender ceremony on board USS Missouri on 2 September 1945 in Tokyo Bay. Geiger also served as an observer to the 1946 atomic bomb tests in Bikini Lagoon, and his somber evaluation of the vulnerability of future surface ship-to-shore assaults to atomic munitions spurred Marine Corps development of the transport helicopter. General Geiger died in 1947.
MajGen Pedro A. del Valle
Major General Pedro A. del Valle, USMC, commanded the 1st Marine Division. Del Valle was 51, a native of San Juan, Puerto Rico, and a 1915 graduate of the Naval Academy. He commanded the Marine Detachment on board the battleship Texas in the North Atlantic during World War I. Subsequent years of sea duty and expeditionary campaigns in the Caribbean and Central America provided del Valle a vision of how Marines might better serve the Navy and their country in war. In 1931 Brigadier General Randolph C. Berkeley appointed then-Major del Valle to the “Landing Operations Text Board” in Quantico, the first organizational step taken by the Marines (with Navy gunfire experts) to develop a working doctrine for amphibious assault. His provocative essay, “Ship-to-Shore in Amphibious Operations,” in the February 1932 Marine Corps Gazette, challenged his fellow officers to think seriously of executing an opposed landing. A decade later, del Valle, a veteran artilleryman, commanded the 11th Marines with distinction during the campaign for Guadalcanal. More than one surviving Japanese marveled at the “automatic artillery” of the Marines. Del Valle then commanded corps artillery for IIIAC at Guam before assuming command of “The Old Breed” for Okinawa. General del Valle died in 1978.
