Resulted in the permanent establishment of US Army Airmobile Divisions. Ia Drang was the US Army's first official Airmobile Division battle .
The Battle of Ia Drang was fought from November 14 to November 18, 1965 between the United States and North Vietnam. The result of the battle was inconclusive, with both sides claiming victory.
Khe Sanh, la Drang, Dak To, Hue, Kim Son and Con Thien.
The new experimental "air cavalry" was looking for a fight; the NVA accepted the challenge.
The US Army's experimental "Airmobile" Division was deployed to the Ia Drang to destroy communist units in that region. NVA regular units were stationed there, and two battalions of US Army regulars engaged them for 3 days.
Ia Drang; GI's pronounced it "I Drang." 1965, a new US Army experimental division, "Airmobile" , choppered into NVA territory. First large scale clash involving the new aluminum M16 assault rifle and the new assault helicopter (UH-1 Iroquois/aka Huey). Prior to 1965, the US Army & US Marines were using the wood stocked M-14 service rifle and flying into combat with CH-21's (Army) and CH-34 Choctaw (Marines) helicopters.
The first military helicopter insertion of troops into a zone of conflict was done by the Royal Marines in November of 1956, during the Suez Canal Crisis in Egypt. In Vietnam, the first air assaults were actually performed by South Vietnamese (ARVN) troops in US helicopters, beginning in December of 1961.The event you're probably thinking of, and what the movie We Were Soldiers is centred around, is the Battle of La Drang, which began on 14 November, 1965 - almost four full years after the ARVN forces had begun performing air assault missions, and a full nine years after the Royal Marines had done it - which occurred in the La Drang Valley, near the border of Vietnam and Cambodia.
Two battalions, over 300 dead in 3 days of fighting.
The Battle of Ia Drang is the subject of We Were Soldiers, Once... And Young, by Harold Moore and Joseph Galloway and is considered to be among the first "battles" of Vietnam. From the amazon.com description: "In November 1965, some 450 men of the 1st Battalion, 7th Cavalry, under the command of Lt. Col. Hal Moore, were dropped by helicopter into a small clearing in the Ia Drang Valley. They were immediately surrounded by 2,000 North Vietnamese soldiers. Three days later, only two and a half miles away, a sister battalion was chopped to pieces." Mel Gibson heroically acted out all this stuff in a movie a few years back. The answer depends a little on when you consider that the Vietnam war began. Some people say that the two American (civilian) pilots that were shot down & killed while resuppling French troops at Dien Bien Phu in 1954 can be considered the first American "casualties" of Vietnam, although clearly they were not official military personnel nor was American directly involved yet. The US military points to Dec. 1961 as their initial military deployment to Vietnam, when we sent over 400 helicopters and troops to fly & maintain them. Of course, there had been American military "advisors" in South Vietnam since the late 1950's. The American advisors killed at Ap Bac in Jan. 1963 are often considered the first military casualities. However, if you are talking about the first American "battle" deaths (rather than "advisors" w/ South Vietnamese troops), that would probably be during Operation Starlite in August 1965 (a few hundred Americans died). That operation was a few months before the battle at la Drang.
It was the first time American soldiers battled the the North Vietnamese soldiers in a large battle . The use of the airborne (helicopters) were also tested . Ia Drang cost the Americans a heavy toll along with the enemy giving way to war of atrrition , and "body counts" that gauged a units sucess . Both sides claimed a victory .
