Operation Junction City was a major search-and-destroy campaign led by the United States Army during 1967. Learn about the operation, including the use of American paratroopers, the battles and the results, in this video lesson.

The 1967 Campaign

The goal for the United States during 1967 was to begin driving out elements of the National Liberation Front (NLF), the insurgent force of North Vietnam, from the III Corps Tactical Zone in South Vietnam. In January, the United States Army successfully launched Operation Cedar Falls, which began the campaign of combating and eliminating the enemy within the region.

The positive results led to General William Westmoreland, commander of the Military Assistance Command, Vietnam, to organize a plan. This plan was codenamed Operation Junction City and was meant to eliminate the 9th NLF Division, as well as its coordinating center, known as the Central Office for South Vietnam (COSVN), from the III Corps Tactical Zone.

Planning

American intelligence suggested that the main elements of the 9th NLF Division and COSVN were located within the Tay Ninh province, which was also referred to as War Zone C. The American military command needed to proceed with caution when creating a strategy to combat the enemy within the region due to its ability to escape and seek asylum in neighboring Cambodia. As a result, the military tactic of encirclement, or surrounding and eliminating the enemy, was pursued.

Westmoreland ordered the United States Army's 1st and 25th Infantry Divisions, as well as the 11th Armored Cavalry Regiment and the 173rd Airborne Brigade, into War Zone C. The use of the 173rd was a seminal decision by Westmoreland as this was the first and only deployment of a paratrooper division during the Vietnam War. Notwithstanding, American military leadership developed the 'horseshoe' strategy.

The goal was to establish a 'horseshoe,' or 'U' shape, perimeter around the suspected location of the 9th NLF Division and COSVN. The 'U' was also expected to prevent the enemy from retreating into Cambodia. After the defensive perimeter was pitched by the 173rd, the expectation was that elements from the 25th and 11th would march in from the open end of the 'U' and crush the enemy. Unfortunately, everything looked better on paper.

Phase I of Junction City

The opening salvo of Junction City was launched on February 22, 1967. The 173rd quickly established the 'horseshoe' shape and ground forces began conducting search-and-destroy operations to eliminate the suspected enemy within the region. Through the first five days of the campaign, the results were negligible. In fact, the majority of COSVN had been relocated into Cambodia prior to the American arrival. Worse yet, the enemy began targeting American forces through hit-and-run tactics.

Throughout the early days of March, the NLF began ambushing the United States on a regular basis. The sound American leadership was quickly able to reassess the situation and launch a counterattack, but the results, again, were unimpressive. Frustrated over the early results in War Zone C, Westmoreland ended the first phase of Junction City on March 15. The United States, however, was not ready to concede to the enemy. Immediately following the end of the first phase, Westmoreland ordered the beginning of phase II of Junction City on March 18.

Phase II

The American military leadership did not originally anticipate a second phase to Junction City, because they thought the overwhelming 'horseshoe' strategy would be enough to complete the main objective of eliminating the 9th NLF Division and COSVN. Nevertheless, Westmoreland approved phase II of the operation, which shifted American forces east of the original 'horseshoe' location and focused more on search-and-destroy and less on encirclement. The emphasis on attrition warfare led to three violent clashes between the United States and the NLF from March to May.

The first engagement occurred at Firebase Gold on March 21 and was known as the Battle of Suoi Tre. The United States had established the firebase following the renewal of Junction City. American intelligence expected an enemy attack to occur on the night of March 20, if at all. However, unexpectedly on the morning of March 21, the 272nd NLF Regiment launched a significant attack against Firebase Gold. The Americans were initially overwhelmed and on the verge of defeat until reinforcements arrived. Once the United States regained the upper hand, the 272nd Regiment was annihilated. Roughly 650 enemy soldiers perished during the battle while the United States suffered losses of 31.
