Facsimile Lincoln letter documents the presidential order for the largest mass-hanging in United States history, when 38 Sioux Indians were executed at Mankato, Minnesota, December 26, 1862, for their part in the Sioux Outbreak of 1862. More than three hundred Indians were condemned to death by a shoddy military commission but the President's approval was required before any execution could take place. In the midst of the American Civil War, President Lincoln reviewed the military commission record of each condemned prisoner before finally choosing 39 (one Indian received a last-minute reprieve) Indians for execution. Lincoln stated that he only wanted to execute those found guilty of rape or murder, not merely participation in the uprising. The mass execution took place with the mass gallows constructed upon the Main Street of Mankato, MN directly opposite the jail. At an executive council meeting of the Minnesota Historical Society of June 12, 1876, Henry Sibley suggested that the "celebrated manuscript order" be lithographed and distributed. This being a copy of that facsimile, of which six are known to exist today, according to OCLC, (January 2018).
