Objective
A search-and-destroy operation meant to combat test the 196th Light Infantry Brigade against light guerrilla opposition
Description
This operation began as a single battalion air assault leading to a search-and-destroy mission. By the time it ended in November, it had expanded into the largest U.S. Joint operation of the war at that time. During Phase I, there was relatively little contact with the VC as the 196th Infantry Brigade conducted operations in the area. In late October / early November(?) the 196th Brigade and the 1st Battalion, 27th Infantry encountered the 9th VC Division. During Phase II, the 27th Infantry and the 9th VC Division's Regiments fought a major three day battle. More contacts with the VC expanded the operation and command eventually passed from the 1st Infantry Division to II Field Force, the U.S. headquaters near Saigon. During Phase III, the 1st Infantry Division took over the fight. Soon afterwards, the 3d Brigade, 1st Division moved into Suoi Da and the 1st Battalion, 28th Infantry moved to a landing zone to the north. The 2d Battalion, 28th Infantry had cleared the area and both battalions were in position by nightfall. On 8 November, reconnaissance-by-fire began under the 1st Battalion's command. The VC began to use intense fire and the VC began to assault the perimeter. 1st Battalion artillery fire and air strikes defeated the VC. The operation included many other battles between the Allied forces and the Communists, but the battle on the 8th was probably the most significant. At its conclusion, a large base camp was discovered which housed one of the largest weapons caches found up to that time. Operation ATTLEBORO illustrated that, due to better maneuverability and firepower, the Allies had an advantage in stand-up fights. This would be tested again in later operations.
