COLONEL STEPHEN COPELAND
DESIGNATION: 3rd Regiment of Tennessee Militia DATES: January 1814 - May 1814 MEN MOSTLY FROM: Overton, Smith, Wilson, Franklin, Warren, Bedford, and Lincoln Counties CAPTAINS: John Biler(Byler), John Dawson, William Douglass, William Evans, Solomon George, William Hodges, John Holshouser, Alexander Provine, Richard Sharp, George W. Still, James Tait, Moses Thompson, Allen Wilkinson, David Williams. BRIEF HISTORY: There were approximately 660 men in this regiment. They were part of a brigade led by General Thomas Johnson (the other regiment of Johnson's brigade was led by Colonel R. C. Napier). Jackson's report of the Battle of Horseshoe Bend (27 March 1814) mentions that Copeland's regiment was held in reserve during this engagement. But a part of the regiment saw action, as muster rolls show casualties from this battle in the companies of Captains Moses Thompson and Allen Wilkinson. Their line of march took them from Fayetteville (where they were mustered into service), through Fort Deposit, Fort Strother, and finally to Fort Williams.
