"The Center Of Military History (CMH), which reports to the Administrative Assistant to the Secretary of the Army, is responsible for the appropriate use of history throughout the United States Army. Traditionally, this mission has meant recording the official history of the Army in both peace and war, while advising the Army Staff on historical matters. In terms of this tradition, the Center traces its lineage back to those historians under the Secretary of War who compiled the Official Records of the Rebellion, a monumental history of the Civil War begun in 1874, and to a similar work on World War I prepared by the Historical Section of the Army War College."
