799. GOUVERNEUR K. WARREN (1830-1882) Union major general who fought at Antietam, Fredericksburg, and at Gettysburg, where he is credited with saving the Union left flank from being rolled up by a Confederate attack on Little Round Top. Fine A.L.S.. "G.K. Warren," 1p, small 8vo, on his imprinted personal stationery, Newport, RI, Aug. 31, 1874, to "Mr. H.W. Clarke, Sec'y 185th N.Y. Regt. Assn.," in part: "...I have the honor to acknowledge the receipt of your kind invitation to the tenth annual Reunion of your regiment and to say how glad I would be to meet with you if I could...". Warren was not yet exonerated in 1874, and appearing at a reunion, with the awful stain proffered by Sheridan and Grant, would be too painful and the embarrassment of meeting either of these two would have been overwhelming. Slight ink-smudging, otherwise in very good condition. Uncommon. $400-500
