Third Seminole WarAmerican Civil War Truman Seymour (September 24, 1824 – October 30, 1891) was a career soldier and an accomplished painter.

After spending two years at Norwich, Seymour received an appointment to the United States Military Academy at West Point.

West Point's Class of 1846 stands as one of the most illustrious in the academy's storied history with George McClellan, Thomas J.

[1] After returning to the United States following the war, he became an assistant professor of drawing at West Point from 1850 to 1853 and fought against the Seminoles in Florida from 1856 to 1858.

When the Civil War began in 1861, Seymour commanded an artillery company in the defense against the Confederate assault on Fort Sumter, after which he received the brevet of major.

Major Seymour commanded the 5th Regiment of Artillery and the U.S. Camp of Instruction at Harrisburg, Pennsylvania, from December 1861 to March 1862.

Seymour performed well at the battles of Second Bull Run, South Mountain, and Antietam in the latter half of 1862, especially in his brigade's capture of Frosttown Gap, Maryland, on September 14.

Maj. Gen. Quincy A. Gillmore, commanding general of the Department of the South, placed Seymour in charge of the newly created District of Florida.

General Seymour's force returned, defeated, to Jacksonville, where Union troops retained control until the war ended.

He then returned to Virginia and led Robert H. Milroy's former brigade as part of the Third Division of VI Corps in the Battle of the Wilderness that May.

After his exchange on August 9, Seymour took command of the Third Division of VI Corps, after James B. Ricketts was wounded, in the last stages of the Shenandoah Valley and the final battles of Petersburg, the Sayler's Creek, and the Appomattox Campaign.
