On 18 July 1950, it was D-minus 59 for the Marine reservists who would hit the beaches at Inchon. These young civilians were doubtless more interested in major league baseball standings at the moment than in hydrographic conditions at the Korean seaport they would assault within two months. Yet the proposed amphibious operation moved a long step closer to reality on the 18th when Major General Oliver P. Smith left Washington under orders to assume command of the 1st Marine Division at Camp Pendleton, California.

A graduate of the University of California in 1916, General Smith had been commissioned a Marine second lieutenant at the age of 24 in the first World War. After serving in Guam during that conflict, he saw duty at sea and in Haiti during the early 1920’s, followed by studies at the Army Infantry School, Fort Benning, Georgia, and duty as an instructor in the Marine Corps Schools at Quantico.

In Paris, while attached administratively to the office of the U. S. Naval Attaché, he took the full two-year course at the École Supérieure de Guerre, and afterwards he was an instructor for three more years at the Marine Corps Schools. He had an extensive experience of hard-fought amphibious operations during World War II as a regimental commander in the Talasea, New Britain, landing, as ADC of the 1st Marine Division at Peleliu, and as deputy chief of staff of the U. S. Tenth Army on Okinawa. Returning with the rank of brigadier, he became Commandant of the Marine Corps Schools; and after putting up a second star, the tall, slender, white-haired general served as Assistant Commandant at Marine Corps Headquarters in Washington.

At the outbreak of the Korean conflict, Major General Graves B. Erskine had commanded the 1st Marine Division. Following his assignment to a secret State Department mission in southeast Asia, General Smith was named as his relief.

The division had meanwhile been reduced to 3,386 officers and men as compared to a strength of 7,789 on 30 June 1950. It had been stripped of its principal operating elements to build up the 1st Provisional Marine Brigade, which numbered about 5,000 officers and men when it sailed from San Diego to the Far East on 14 July under the command of Brigadier General Edward A. Craig.[30]

At El Toro, the near-by Marine Corps Air Station, it was the same story. The 1st Marine Aircraft Wing, with a total strength of 4,004 officers and men on 30 June, provided most of the 1,548 officers and men of Marine Aircraft Group 33, the air component of the Brigade, commanded by Brigadier General Thomas J. Cushman, who was also deputy Brigade commander.[31]

Expansion to Full Peace Strength

General Smith had known before his arrival at Pendleton that his first task would be the building up of the 1st Marine Division to full peace strength. As early as 12 July, a dispatch from CNO had warned CinCPacFlt that this expansion would take place, including the elements of the Brigade.[32] And on 15 July General Shepherd directed Brigadier General Harry B. Liversedge, temporary CG 1st Marine Division, to extend the work day and work week while intensifying training and making preparations to expand.[33]
