1st Lt. Williams was serving as executive officer of a Special Forces Detachment when an estimated Vietcong reinforced regiment struck the camp and threatened to overrun it and the adjacent district headquarters.

He awoke personnel, organized them, determined the source of the insurgents' main effort and led the troops to their defensive positions on the south and west walls.

To reach the other compound, he traveled through darkness but was halted in this effort by a combination of shrapnel in his right leg and the increase of the Vietcong gunfire.

As daylight arrived and the Vietcong continued to besiege the stronghold, firing a machinegun directly south of the district building, he was determined to eliminate this menace that threatened the lives of his men.

Taking a 3.5 rocket launcher and a volunteer to load it, he worked his way across open terrain, reached the berm south of the district headquarters, and took aim at the Vietcong machinegun 150 meters away.

As morning turned to afternoon and the Vietcong pressed their effort with direct recoilless rifle fire into the building, he ordered the evacuation of the seriously wounded to the safety of the communications bunker.

When informed that helicopters would attempt to land as the hostile gunfire had abated, he led his team from the building to the artillery position, making certain of the timely evacuation of the wounded from the communications area, and then on to the pickup point.

1st Lt. Williams' extraordinary heroism, are in the highest traditions of the U.S. Army and reflect great credit upon himself and the Armed Forces of his country.
