This collection consists of a single leaf bearing a letter from Joseph Hooker, commanding general of the Army of the Potomac, regarding the enlistment of two soldiers (Henry W. Peters and William H. Tapp). Written on February 19, 1863, the letter requests that the adjutant general undertake an inquiry regarding the enlistment of the two, to determine whether they were deserters from another regiment at the time of their enlistment. With Hooker's letter are notes from the adjustant general's office and a response from Captain B. F. Harris of the 11th Pennsylvania Infantry, stating that the two soldiers had been in his regiment before having been taken prisoner at Manassas, paroled, and sent to Camp Chase, Ohio, and that he had not seen them again until they had enlisted in an artillery battery. The notes mention two enclosed documents which apparently have since become separated from the letter.
