UNITED STATES, Appellee v WILLIAM L. CALLEY, JR., First Lieutenant, U.S. Army, Appellant.
December 21, 1973

In November 1969, Stanley R. Resor, Secretary of the Army, and General William C. Westmoreland, U.S. Army Chief of Staff, directed Lieutenant General William R. Peers, U.S. Army, to “explore the nature and scope of the original Army investigations of what occurred on 16 March 1968 in Son My Village, Quang Ngai Province, Republic of Vietnam.” This collection of materials, commonly known as the “Peers Inquiry,” which provides the results of General Peers’ investigation of the “My Lai incident”— later also known as the “My Lai massacre”— is divided into four volumes: the report, witness testimonies, exhibit materials, and CID [U.S. Army Criminal Investigation Command] statements.
