"Everybody was taking pot shots at him, seeing how accurate they were," Henry said in his statement.
Capt. Donald C. Reh, a 1964 graduate of West Point, took command of B Company in November 1967. Two months later, enemy forces launched a major offensive during Tet, the Vietnamese lunar New Year.
In the midst of the fighting, on Feb. 7, the commander of the 1st Battalion, Lt. Col. William W. Taylor Jr., ordered an assault on snipers hidden in a line of trees in a rural area of Quang Nam province. Five U.S. soldiers were killed. The troops complained bitterly about the order and the deaths, Henry said.
The next morning, the men packed up their gear and continued their sweep of the countryside. Soldiers discovered an unarmed man hiding in a hole and suspected that he had supported the enemy the previous day. A soldier pushed the man in front of an armored personnel carrier, Henry said in his statement.
"They drove over him forward which didn't kill him because he was squirming around, so the APC backed over him again," Henry's statement said.
Then B Company entered a hamlet to question residents and search for weapons. That's where Henry set down his weapon and lighted a cigarette in the shelter of a hut.
A radio operator sat down next to him, and Henry was listening to the chatter. He heard the leader of the 3rd Platoon ask Reh for instructions on what to do with 19 civilians.
"The lieutenant asked the captain what should be done with them. The captain asked the lieutenant if he remembered the op order (operation order) that came down that morning and he repeated the order which was 'kill anything that moves,' " Henry said in his statement. "I was a little shook because I thought the lieutenant might do it."
Henry said he left the hut and walked toward Reh. He saw the captain pick up the phone again, and thought he might rescind the order.
Then soldiers pulled a naked woman of about 19 from a dwelling and brought her to where the other civilians were huddled, Henry said.
"She was thrown to the ground," he said in his statement. "The men around the civilians opened fire and all on automatic or at least it seemed all on automatic. It was over in a few seconds. There was a lot of blood and flesh and stuff flying around .
"I looked around at some of my friends and they all just had blank looks on their faces . The captain made an announcement to all the company, I forget exactly what it was, but it didn't concern the people who had just been killed. We picked up our stuff and moved on."
Henry didn't forget, however. "Thirty seconds after the shooting stopped," he said, "I knew that I was going to do something about it."
For his combat service, Henry earned a Bronze Star with a V for valor, and a Combat Medical Badge, among other awards. A fellow member of his unit said in a sworn statement that Henry regularly disregarded his own safety to save soldiers' lives, and showed "compassion and decency" toward enemy prisoners.
When Henry finished his tour and arrived at Ft. Hood, Texas, in September 1968, he went to see an Army legal officer to report the atrocities he'd witnessed.
The officer advised him to keep quiet until he got out of the Army, "because of the million and one charges you can be brought up on for blinking your eye," Henry says. Still, the legal officer sent him to see a Criminal Investigation Division agent.
