The sum total of these contributions, I feel, is an objective, readable account of this important battle which honors the valiant American and South Vietnamese troops who held Khe Sanh. I can think of no more fitting tribute to these men--both living and dead--than to simply relate the events as they happened. This, then, is their story. [Illustration: Handwritten signature] L. F. CHAPMAN, JR. General, U.S. Marine Corps Commandant of the Marine Corps REVIEWED AND APPROVED 28 May 1969 FOREWORD As the commander of the United States Military Assistance Command, Vietnam, during the battle of Khe Sanh, I welcome publication by the U. S. Marine Corps of this historical study. The Marines' heroic defense of the Khe Sanh area against numerically superior North Vietnamese forces stands out among the many battles fought to defend the Republic of Vietnam against Communist aggression. The enemy's primary objective of his 1968 TET Offensive was to seize power in South Vietnam by creating a general uprising and causing the defection of major elements of the Armed Forces of the Republic of Vietnam. In conjunction with this, the enemy apparently expected to seize by military action large portions of the northern two provinces lying just south of the Demilitarized Zone and there to set up a "liberation government." The virtually unpopulated Khe Sanh Plateau, which lay astride the enemy's principal avenue of approach from his large base areas in Laos, was obviously an initial objective of the North Vietnamese Army. Its seizure would have created a serious threat to our forces defending the northern area and would have cleared the way for the enemy's advance to Quang Tri City and the heavily populated coastal region. There is also little doubt that the enemy hoped at Khe Sanh to attain a climactic victory, such as he had done in 1954 at Dien Bien Phu, in the expectation that this would produce a psychological shock and erode American morale. My subordinate commanders and I were particularly sensitive to heavy fighting in the populated areas, since this would result in substantial destruction to the towns and villages and cause unnecessary suffering by the civilian population. We wanted to avoid this situation to the greatest extent possible by denying the enemy freedom of movement through the Khe Sanh area and into the coastal region. At that time we did not have sufficient troops, helicopters, or logistical support in the northern provinces to accomplish this entirely through mobile operations, and competing requirements for troops and resources did not permit immediate reinforcement from other areas of South Vietnam. The situation was further complicated by long periods of fog and low cloud ceilings during January, February, and March, which made helicopter operations difficult and hazardous.
