We Were Soldiers Once... and YoungJoseph L. Galloway et Harold G. Moore1992

Vietnam. November 1965. 450 men of the 1st Battalion, 7th Cavalry, under the command of Lt. Col. Hal Moore, are dropped by helicopter into a small clearing in the Ia Drang Valley and immediately surrounded by 2,000 North Vietnamese soldiers. Three days later, only two and a half miles away, a sister battalion is chopped to pieces. Together, these actions at the landing zones X-Ray and Albany constitute one of the most savage and significant battles of the Vietnam War and set the tone of the conflict to come.
