Vietnam War

Oct 15, 1966:

Operation Attleboro continues in Tay Ninh Province

U.S. troops move into Tay Ninh Province near the Cambodian border, about 50 miles north of Saigon, and sweep the area in search of Viet Cong as part of Operation Attleboro, which had begun in September.

The purpose of this operation was to find and eliminate all enemy troops west of the Michelin rubber plantation. It was the largest U.S. operation to date and included elements of the U.S. 1st and 25th Infantry Divisions; the 196th Light Infantry Brigade; the 173rd Airborne Brigade; and at least two South Vietnamese army battalions. Engagements continued through the middle of November. At the height of the fighting, a record 20,000 Allied troops were committed. They were opposed by major elements of the 9th Viet Cong Division, one of the best-trained Communist formations. Communist resistance was strong because the Tay Ninh area contained the site of the principal Viet Cong command center for guerrilla operations in South Vietnam and the central office of the National Liberation Front. Operation Attleboro ended on November 25. By then, 2130 Viet Cong and North Vietnamese troops had been killed.
