Vietnam War

Oct 10, 1965:

1st Cavalry Division commences operations

In the first major operation since arriving the previous month, the U.S. 1st Cavalry Division (Airmobile) joins with South Vietnamese Marines to strike at 2,000 North Vietnamese troops 25 miles from An Khe in the Central Highlands.

The 1st Cavalry Division was a new kind of division, which was built around the helicopter and the airmobile concept. The division contained 434 helicopters and had the capability to move one-third of its combat power at one time into terrain inaccessible to normal infantry vehicles. During its first major mission, faulty U.S.-South Vietnamese coordination prevented their forces from entrapping the North Vietnamese Army 325th Infantry Division, but they managed to reopen Route 19, between Pleiku and An Khe, the main east-west supply route in the region. During the course of its employment in South Vietnam, the "First Team," as the 1st Cavalry Division came to be known, would prove to be one of the most effective U.S. combat units in the war.
