The U.S. War Department had different motives: the historians were to inform the soldiers and the nation as a whole, as well as the high command. Their narratives were to be comprehensive, impartial, and sufficiently authoritative to form an important source for the studies of future historians. In the meantime, short histories of operations, later called the American Forces in Action series, were to be published for the men who took part.
It was soon discovered that the type of history desired could not be written from the archives alone, despite prodigious record keeping. The paperwork of one division for a single week would fill a filing cabinet. The trouble was simply that the records constituted truth in parade dress. “On the actual day of battle,” Gen. Sir Ian Hamilton once reflected, “naked truths may be picked up for the asking; by the following morning they have begun to get into their uniforms.” The messages, intelligence summaries, field orders, operations reports, and all the other records still left huge gaps in the story of the action; they were often meaningless or misleading on the most vital questions. As a result, officers and enlisted historians were assigned to the battlefronts to see for themselves and write the first drafts of history on the spot.
