These generals' reports of service represent an attempt by the Adjutant General���s Office (AGO) to obtain more complete records of the service of the various Union generals serving in the Civil War. In 1864, the Adjutant General requested that each such general submit ". . . a succinct account of your military history . . . since March 4th, 1861." In 1872, and in later years, similar requests were made for statements of service for the remaining period of the war.
