Thomas Grimke Rhett was born in South Carolina on August 2, 1821, as Thomas Moore Smith.[2][3] He was the son of James Smith (Rhett) (1797–1855) and Charlotte Haskell (Rhett) (1794–1871).[2][4] The family changed their surname to Rhett in 1837.[2] Rhett graduated from the United States Military Academy on July 1, 1845, ranking 6th in a class of 41 cadets.[2][3][5]
On June 10, 1846, Rhett married Ann Graham Mason, the daughter of Thomson Francis Mason (1785–1838), a descendant of George Mason.[4] The Rhetts had seven children by 1854 but the source does not show any of them living to adulthood.[8]
Rhett was promoted to first lieutenant, in the U.S. Army's Regiment of Mounted Riflemen, reorganized in 1861 as the 3rd Cavalry Regiment (United States), on April 18, 1847.[2][3] He was appointed brevet captain for gallantry at the Siege of Puebla, Mexico, October 12, 1847.[2][3][6][9] Rhett was a member of the Aztec Club of 1847, which was founded as a military society of officers who served with the United States Army in the Mexican-American War.[10]
After the surrender of Fort Bliss to a Confederate force, Rhett reported to the provisional Confederate government at Montgomery, Alabama. He was appointed major of artillery in the Confederate States Army on March 16, 1861, which was not the level of appointment he desired.[6][12] He then returned to South Carolina where he was commissioned brigadier general in the South Carolina Militia by GovernorFrancis W. Pickens.[2][6][13] It was only on April 1, 1861, that Rhett officially resigned from the United States Army.[2][6][12]
Rhett did not serve as a brigadier general in the South Carolina Militia.[2] In April 1861, he served as a volunteer aide-de-camp to Confederate General Pierre G. T. Beauregard.[3] On May 16, 1861, he was appointed major and assistant adjutant general to Colonel George H. Terrett's Virginia Brigade in the Provisional Army of Virginia, which supported the Confederacy before Virginia formally seceded from the Union and in June merged into the Confederate States Army.[12][14]
Rhett was major, assistant adjutant general and chief of staff to General Joseph E. Johnston from July 20, 1861, until May 31, 1862.[2][12] From July 20, 1861, to March 14, 1862, his official position was Chief of Staff and Assistant Adjutant General in the Confederate Army of the Potomac.[3] When the name of the army was changed to the Army of Northern Virginia, Rhett was Chief of Staff of the Army for the Army of Northern Virginia from March 14, 1862, to May 31, 1862, when Johnston was wounded at the Battle of Seven Pines and replaced by General Robert E. Lee.[2][3][6]
Rhett was then transferred to the Trans-Mississippi Department.[2][6][15] From May 1862 to April 1863, Rhett was chief of ordnance in the District of Arkansas, Trans-Mississippi Department of the Confederacy, serving under Lieutenant GeneralTheophilus H. Holmes starting October 22, 1862.[2][3][12] From April 30, 1863, to the end of the war in June 1865, Rhett was chief of artillery in the Trans-Mississippi Department, under the command of GeneralE. Kirby Smith.[2][12][16]
Later life
After the war Rhett left the United States and was appointed colonel of ordnance in the Egyptian army from 1865 until 1873.[2][6][12][16] Then, he had a paralytic stroke, and resigned. He remained abroad in Europe until 1876. He was not able to find relief from his condition there.[6] He returned to the United States and lived with relatives in Baltimore, Maryland, in 1876.[2][6][16]
