Kill anything that moves. Moments later, the 19 villagers lay dead or dying. Back home in California, Henry published an account of the slaughter. Yet he and other Vietnam veterans who spoke out about war crimes were branded traitors and fabricators. No one was ever prosecuted. Now, nearly 40 years later, declassified Army files show that Henry was telling the truth. The files are part of a once-secret archive ... that shows that confirmed atrocities by U.S. forces in Vietnam were more extensive than was previously known. The Times...obtained copies of about 3,000 pages -- about a third of the total -- before government officials removed them from the public shelves, saying they contained personal information that was exempt from the Freedom of Information Act. The documents detail 320 alleged incidents that were substantiated by Army investigators. Many war crimes did not make it into the archive. The archive ... includes investigative files, sworn statements by witnesses and status reports for top military brass. The records describe recurrent attacks on ordinary Vietnamese. Hundreds of soldiers ... described a violent minority who murdered, raped and tortured with impunity. Abuses ... were uncovered in every Army division that operated in Vietnam. Ultimately, 57 [soldiers] were court-martialed and just ... fourteen received prison sentences ranging from six months to 20 years, but most won significant reductions on appeal. The stiffest sentence went to a military intelligence interrogator. He served seven months of a 20-year term. Many substantiated cases were closed with a letter of reprimand, a fine or, in more than half the cases, no action at all.
