November 14 in Military History — On This Day

Battle of Ia Drang Valley

The first major battle between US Army troops and the North Vietnamese Army, fought in the central highlands. Air cavalry — helicopter-transported infantry — allowed Lt. Col. Hal Moore to move rapidly but also led to his 400-man battalion being surrounded by 2,000 NVA. Three days of savage fighting proved the NVA would stand and fight Americans directly, contrary to US expectations.

Proved helicopters could transform tactical mobility but also showed the NVA was a formidable force willing to fight at close quarters to neutralize US firepower. The after-action body counts — a metric that would define and distort the entire war — showed a 12:1 kill ratio. US commanders concluded they were winning. They were not.

Battle of Ia Drang — First Major Vietnam Battle

The U.S. 7th Cavalry (Custer's old regiment) air-assaulted into the Ia Drang Valley and fought North Vietnamese regulars in the first major confrontation of the Vietnam War. The Americans were surrounded and nearly overrun before air support turned the tide.

Ia Drang established the air cavalry doctrine for the entire Vietnam War and showed both sides what they faced; the North Vietnamese concluded they could not fight Americans in the open, turning to guerrilla tactics.

Outcome

American tactical victory; NVA shifts to guerrilla warfare
