John McAuley Palmer (1817-1900) was a Civil War Union Major General, 15th Illinois Governor, Illinois State Senator, United States Senator and United States presidential candidate. Prior to the Civil War, Palmer was an ardent abolitionist and served in the Illinois State Senate as both a regular Democrat and independent Democrat. In 1856, however, he played a major role in the formation of the Illinois Republican party and ran as a Republican in 1859 but was defeated. During the Civil War, Palmer reached the rank of major general, commanded a division under John Pope, and was promoted to the command of XIV Corps which he led at Chattanooga and in the Atlanta campaign. He was relieved from command at his own request in August 1864 "as a result of a quibble over relative rank, an incident which did not reflect particularly favorably on him." The incident resulted in him being reassigned to command all Federal forces in Kentucky. He remained in the Army until 1866. During his postbellum career, Palmer was elected governor of Illinois on the Republican ticket in 1868 but soon turned his allegiance back to the Democratic party. In 1891 he was elected to the U.S. Senate as a Democrat. Five years later Palmer and ex-Confederate General Simon Buckner ran an unsuccessful bid for U.S. president and vice president respectively as Gold Democrat candidates. Palmer and Buckner received just over 1% of the vote. Comes with research related to Palmer including military service records, letters (copies) and secondary source material with letters including one letter from dealer Arnold Chernoff to the current consignor's father about the sale of this revolver.
