Flares from planes light a field covered with the dead and wounded of the ambushed battalion of the U.S. 1st Cavalry Division in the Ia Drang Valley, Vietnam, on November 18, 1965, during a fierce battle that had been raging for days. Units of the division were battling to hold their lines against what was estimated to be a regiment of North Vietnamese soldiers. Bodies of the slain soldiers were carried to this clearing with their gear to await evacuation by helicopter.
