Appointed U.S. Surgeon General on April 25, 1862, Hammond radically reorganized the war-time Medical Department. He was court-martialed and dismissed from the service in 1864 after a political struggle with Secretary of War Stanton; the charges were reviewed in 1879 and Hammond was exonerated, restored to rank, and placed on the retired list.
Signature, with closing, “Yours sincerely, William A. Hammond,” on a 1 ¾” x 4 ¾” slip of paper, removed from a letter; tipped to slightly larger backing.
Lightly and evenly toned, with a collector’s pencil notation in the lower left corner.
