Roy Geiger

Further training followed and in July 1918, he arrived in France. He served with 5 Group, Royal Air Force at Dunkirk. He commanded a squadron of the First Marine Aviation Force and was attached to the Day Wing, Northern Bombing Group. He was detached to the United States in January 1919. For distinguished service in leading bombing raids against the enemy, he was awarded the Navy Cross.

From December 1919 to January 1921, he was a squadron commander with the Marine Aviation Force attached to the 1st Provisional Marine Brigade in Haiti. Upon return to the United States and after duty at the Marine Flying Field, Marine Barracks, MCB Quantico, Virginia, he attended Command and General Staff School at Fort Leavenworth, Kansas. He graduated in June 1925. Again he went to foreign shore duty, commanding Observation Squadron Two with the First Brigade in Haiti.

In August 1927, he returned to Quantico as a squadron officer and instructor at the Marine Corps Schools, and in May 1928, was assigned to duty in the Aviation Section, Division of Operations and Training, at Marine Corps Headquarters. After attending the U.S. Army War College and graduating in June 1929, he was ordered to Quantico, where he was assigned duty as commanding officer, Aircraft Squadrons, East Coast Expeditionary Force. He returned to Washington and served as the officer in charge, Marine Corps Aviation from 1931 to 1935, a billet currently held by a lieutenant general that is now known as the deputy commandant for aviation.[6]

In June 1935, he returned to Quantico as commanding officer, Aircraft One, Fleet Marine Force. From June 1939 to March 1941, he was a student at the Senior and the Advanced Courses, Naval War College, Newport, Rhode Island. This was followed with a brief tour of duty in the Office of the Naval Attaché, London.

In April 1941, Geiger made his way from Lisbon to Gibraltar, where he changed from civilian clothes to his military uniform. He had lunch with the governor at Government House, in a visit which lifted British morale in Gibraltar. He was on his way to the Western Desert, as the first U.S. military observer attached to the British 8th Army. In August, he became commanding general, 1st Marine Aircraft Wing, Fleet Marine Force, in which capacity he was found upon the United States' entry into World War II.

On September 3, 1942, he was stationed at Guadalcanal to lead the Cactus Air Force during the early part of the Guadalcanal Campaign. Until November 4, he was commander of the combined Army, Navy and Marines Air Forces stationed here, of which the 1st Marine Aircraft Wing was part. He was awarded a Gold Star in lieu of a second Navy Cross for his service on Guadalcanal.

His citation reads in part, "Despite almost continuous bombardment by enemy aircraft, hostile naval gunfire and shore based artillery, the combined total of Army, Navy and Marine Corps units stationed at Guadalcanal under Major General Geiger's efficiently coordinated command succeeded in shooting down 268 Japanese planes in aerial combat and inflicting damage on a number estimated to be as great ... Sank six enemy vessels, including one heavy cruiser, possibly sank three destroyers and one heavy cruiser, and damaged 18 other ships, including one heavy cruiser and five light cruisers."

Geiger was recalled to Headquarters Marine Corps in May 1943, to become the Director of Aviation. In November 1943, he returned to the field, this time as commanding general of the I Amphibious Corps and led the corps from November 9, to December 15, 1943, in the Battle of Bougainville, for which he was awarded the Distinguished Service Medal.

Redesignated III Amphibious Corps in April 1944, he led this organization in the invasion and subsequent recapture of Guam during July and August 1944, and in the assault and capture of the southern Palau Islands in September and October of the same year. For those operations he was awarded two Gold Stars in lieu of a second and third Distinguished Service Medal.

Geiger led this corps into action for the fourth time as part of the Tenth Army in the invasion and capture of Okinawa. On June 18, 1945, Geiger assumed command of the Tenth Army following the death in combat of Lt. General Simon Bolivar Buckner Jr. for the final five days of the battle. He was relieved by General Joseph Stilwell. To this day, Geiger remains the only Marine Corps officer to have ever held command of a field army.[7][8] Geiger was appointed commanding general of the Fleet Marine Force, Pacific in July 1945 and was promoted to lieutenant general.[9] Geiger was the only Marine Corps representative at the surrender of Japan aboard the USS Missouri (BB-63) on September 2, 1945.[7]
