Cause

Political instability in Saigon led North Vietnamese leaders to believe South Vietnam's government depended on its military strength. Seeking to exploit this vulnerability, the PAVN and Viet Cong launched the Summer Offensive of 1965, aiming to inflict heavy casualties on ARVN forces. Phước Long Province was chosen as a key target, culminating in the Đồng Xoài campaign.

Event

On the evening of 9 June 1965, the VC 272nd Regiment attacked and seized the Civilian Irregular Defense Group and US Special Forces camp at Đồng Xoài. Subsequent ARVN counterattacks by the 1st Battalion 7/5 Infantry, the 52nd Ranger Battalion, and the 7th Airborne Battalion were met with ambushes by the VC 271st Regiment, resulting in significant South Vietnamese losses before the VC withdrew by 13 June.

Consequence

General Westmoreland ordered elements of the US 173rd Airborne Brigade into the battle zone on 13 June, marking their first commitment to a major engagement in Vietnam. However, the Viet Cong had already withdrawn, and the US paratroopers returned to base without combat contact. The episode highlighted the limits of reactive ARVN counterattacks and accelerated the US decision to take a more direct combat role.
