This volume in the official History of the Marine Corps chronicles the invasion by United States Marines at Inchon in the initial stages of the Korean War. The Battle of Inchon was an amphibious invasion and battle of the Korean War that resulted in a decisive victory and strategic reversal in favor of the United Nations. The operation involved some 75,000 troops and 261 naval vessels, and led to the recapture of the South Korea capital Seoul two weeks later. The code name for the operation was Operation Chromite. The battle began on 15 September 1950 and ended on 19 September. Through a surprise amphibious assault far from the Pusan Perimeter that UN and South Korean forces were desperately defending, the largely undefended city of Incheon was secured after being bombed by UN forces. The battle ended a string of victories by the invading North Korean People’s Army (NKPA). The subsequent UN recapture of Seoul partially severed NKPA’s supply lines in South Korea. The majority of United Nations ground forces involved were U.S. Marines, commanded by General of the Army Douglas MacArthur of the United States Army. MacArthur was the driving force behind the operation, overcoming the strong misgivings of more cautious generals to a risky assault over extremely unfavorable terrain.

The race to the Yalu was on. General of the Army Douglas MacArthur’s strategic triumph at Inchon and the subsequent breakout of the U.S. Eighth Army from the Pusan Perimeter and the recapture of Seoul had changed the direction of the war. Only the finishing touches needed to be done to complete the destruction of the North Korean People’s Army. Moving up the east coast was the independent X Corps, commanded by Major General Edward M. Almond, USA. The 1st Marine Division, under Major General Oliver P. Smith, was part of X Corps and had been so since the 15 September 1950 landing at Inchon. After Seoul the 1st Marine Division had reloaded into its amphibious ships and had swung around the Korean peninsula to land at Wonsan on the east coast. The landing on 26 October 1950 met no opposition; the port had been taken from the land side by the resurgent South Korean army. The date was General Smith’s 57th birthday, but he let it pass unnoticed. Two days later he ordered Colonel Homer L. Litzenberg, Jr., 47, to move his 7th Marine Regimental Combat Team north from Wonsan to Hamhung. Smith was then to prepare for an advance to the Manchurian border, 135 miles distant. And so began one of the Marine Corps’ greatest battles—or, as the Corps would call it, the “Chosin Reservoir Campaign.” The Marines called it the “Chosin” Reservoir because that is what their Japanese-based maps called it. The South Koreans, nationalistic sensibilities disturbed, preferred—and, indeed, would come to insist—that it be called the “Changjin” Reservoir.

Douglas MacArthur's efforts to gain approval for the landing, and the deployment of the Marine units that took part. It also includes profiles of Major Gen. Oliver P. Smith, Col. Lewis B. "Chesty" Puller, Major Gen. Field Harris, Col. Homer L. Litzenberg, Jr., Private First Class Walter C. Monegan, Jr., and Second Lt. Henry A. Commiskey.

Volume II presents in detail the operations of the 1st Marine Division and the 1st Marine Aircraft Wing as a part of X Corps, USA, during and immediately following the Inchon Landing on 15 September 1950. In order to tell a complete story of this historic amphibious operation, the authors have described the mobilization of the Marine Corps reserves to form the components of the Division and Aircraft Wing; the movement to the staging area and the hurried planning for an amphibious landing; the withdrawal of the 1st Provisional Brigade and Marine Air Group 33 from the embattled Pusan Perimeter to amalgamate with the larger force for D-day at Inchon; the seizure of Seoul and its environs, and finally the withdrawal on 7 October to prepare for the Wonsan operation. “THE INCHON LANDING was a major amphibious operation, planned in record time and executed with skill and precision. Even more, it was an exemplification of the fruits of a bold strategy executed by a competent force. The decision to attack at Inchon involved weakening the line against enemy strength in the Pusan Perimeter in order to strike him in the rear. It involved the conduct of an amphibious attack under most difficult conditions of weather and geography. The stakes were high and the risk was fully justified. Had it not been for the intervention of the Chinese Communist Army, the offensive generated by the Inchon attack would have resulted in a complete victory for our arms in Korea. A study of the record of this operation will disclose, with arresting clarity, the decisive power that is to be found in highly trained amphibious forces when their strength is applied at the critical place and time.”- Gen. Lemuel Shepherd
