Hill 875.....
At 18:58 one of the worst friendly-fire incidents of the Vietnam Conflict occurred when a Marine Corps fighter-bomber dropped two 500-pound bombs into 2/503's perimeter. One of the bombs exploded, a tree burst above the center of the position, where the combined command groups, the wounded, and the medics were all located. It killed 42 men outright and wounded 45 more, including the overall on-scene commander, Captain Harold Kaufman. 1Lt. Bartholomew O'Leary, Delta Company Commander, was seriously wounded. (Alpha company's commander had been killed in the retreat up the slope).
