The Battle of Ia Drang, fought from 14 to 18 November 1965 in the Central Highlands2 of South Vietnam, was the first major battle between US forces and the regular North Vietnamese Army3. American airmobile troops, carried in by helicopter, held a surrounded landing zone called X-Ray, then suffered a sharp reverse at a second zone, Albany. Both sides claimed success, and both drew lessons, a preview of the long war of attrition to come.
In November 1965, American soldiers rode helicopters into a valley in the Central Highlands to find the enemy, and found far more of them than expected. At a clearing called LZ X-Ray, the first great battle of America's Vietnam War began.

A new kind of war
As the United States committed ground troops to Vietnam in 1965, it brought a new concept: airmobile warfare, moving infantry by helicopter to strike deep and fast4. The 1st Cavalry Division was sent into the Ia Drang Valley to find and fight the North Vietnamese regulars operating there.
Landing at X-Ray
A battalion under Harold G. Moore was flown into a small clearing designated Landing Zone X-Ray1, close to a hill held in strength by the North Vietnamese under Nguyen Huu An. The Americans had landed almost on top of a far larger force.
The fight for the landing zone
For days the surrounded battalion held X-Ray against repeated mass assaults, calling in artillery and tactical air strikes to keep from being overrun; nearby, waves of B-52 bombers struck the enemy base area on the Chu Pong massif, the first use of the bombers in support of ground troops1. The fighting was desperate and close, but the landing zone held.
Ambush at Albany
As part of the American force marched overland to another clearing, Landing Zone Albany, it was caught in a sudden, close-range ambush and badly mauled5 in some of the most costly fighting of the battle. The two actions together made Ia Drang a bloody introduction to the war.
Why Ia Drang mattered
Ia Drang was the first major test of both American airmobile tactics and the North Vietnamese willingness to stand and fight. Each side took away confidence and hard lessons: the Americans in their firepower and mobility, the North Vietnamese in closing to point-blank range to blunt it1. It foreshadowed the grinding war of attrition that followed, and was later told in the memoir and film We Were Soldiers3.
