About Bryan M. Thomas
Lived 1836 – 1905 (aged 69). Bryan M. Thomas was an American military officer.
Bryan Morel Thomas (May 8, 1836 – July 16, 1905) was an American soldier, farmer, marshal, and educator. He served as an officer in the United States Army, and later in the Confederate States Army during the American Civil War. He was a son-in-law of Jones M. Withers, under whom Thomas would serve in the war. Thomas also participated in and was captured during the 1865 Battle of Fort Blakeley, the conflict's final infantry fight.
Early life and U.S. Army career Thomas was born in 1836 in Milledgeville, Georgia, and gained his primary education while attending Atlanta's Oglethorpe University. On July 1, 1854, he entered the United States Military Academy at West Point. Thomas graduated four years later and stood 22nd out of 54 cadets. On July 1, 1858, he was brevetted as a second lieutenant and assigned to the 8th U.S. Infantry.
With the 8th Infantry, Thomas performed garrison duty in New York and then was stationed in the Utah Territory. On January 19, 1859, he was promoted to second lieutenant and assigned to the 5th U.S. Infantry. He was commissioned as a first lieutenant in the regular Confederate infantry on March 16, and promoted to major in the regular service that same day. In July Thomas was assigned to the 18th Alabama Infantry with the rank of major. Leaving the line service for staff work, Thomas was assigned to command the ordnance in the Confederate Department of Alabama & West Florida on December 20. Assigned to the staff of Maj. Gen. Jones M. Withers, Thomas fought at the Battle of Shiloh on April 6–7, performing a "commendable part in the battle..."
Beginning on January 2, 1863, Thomas was assigned as assistant inspector general of the Withers' Division in the renamed Army of Tennessee. Later in 1863, on the recommendation of Lt. Gen. Leonidas Polk, he was promoted to colonel and given command of the 12th Mississippi Cavalry. This new regiment, the reserve cavalry of Brig. Gen. James H. Clanton's Alabama Brigade, was also variously known as "Col. Thomas's Alabama Cavalry." On August 4, 1864, he was appointed as a "temporary" brigadier general of volunteer troops and that September was assigned brigade command in the defenses in Mobile, Alabama. His appointment was never confirmed by the Confederate Congress so his actual highest grade was colonel.
Fort Blakeley
In 1865 Thomas participated in the Mobile Campaign as part of the Confederate force holding Fort Blakeley in Baldwin County, Alabama. Beginning on April 1 Thomas and the fort was put under siege by the Union forces of Maj. Gen. Edward R. S. Canby. His command—mostly consisting of "boy reserves"—held the right of the Confederate works, on the left was the division of Brig. Gen. Francis Cockrell, and both under Brig. Gen. St. John Richardson Liddell, the garrison commander. At 5:30 p.m. on April 9 the attack came, with simple numbers (around 16,000 Union versus 4,475 Confederate) deciding the assault, which lasted only 20 minutes. In the fight, 3,700 Confederates, Thomas, Cockrell, as well as Liddell were all captured. Thomas was held until June when he was released from Fort Gaines, Alabama, paroled and returned home.
The Bryan M. Thomas Chapter of the United Daughters of the Confederacy was named in his honor.
