Patrick Ronayne Cleburne

Major-General Patrick Ronayne Cleburne (/ˈkleɪbɜːrn/ KLAY-burn; March 16, 1828 – November 30, 1864)[1] was a senior officer of the Confederate States Army who commanded infantry in the Western Theater of the American Civil War.[2]
Born in Ireland,[1] Cleburne served in the 41st Regiment of Foot, a Welsh regiment of the British Army, after failing to gain entrance into Trinity College of Medicine in 1846. Three years later, he immigrated to the United States. At the beginning of the Civil War, Cleburne sided with the Confederate States. He progressed from being a private soldier in the local militia to a division commander.
Cleburne was promoted to brigadier general on March 4, 1862.
He was promoted to major general on December 13,1862.
By late 1863, it had become obvious to Cleburne that the Confederacy was losing the war because of the growing limitations of its manpower and resources. In 1864, he dramatically called together the leadership of the Army of Tennessee and put forth the proposal to emancipate all slaves ("emancipating the whole race upon reasonable terms, and within such reasonable time") in order to "enlist their sympathies" and thereby enlist them in the Confederate Army to secure Southern independence. Cleburne argued that emancipation did not have to include black equality, noting that "necessity and wise legislation" would ensure relations between blacks and whites would not materially change. This proposal was met with polite silence at the meeting, and while word of it leaked out, it went unremarked, much less officially recognized. Cleburne's proposal was vigorously attacked as an "abolitionist conspiracy" by General William H.T. Walker, who strongly supported slavery and also saw Cleburne as a rival for promotion. Walker eventually persuaded the commander of the Army of Tennessee, General Braxton Bragg, that Cleburne was politically unreliable and undeserving of further promotion. "Three times in the summer of 1863 he was passed over for corps commander and remained a division commander until his death."
Cleburne was killed during an ill-conceived assault (which he opposed) on Union fortifications at the Battle of Franklin, just south of Nashville, Tennessee, on November 30, 1864.
