Neill served as a captain under Major William Woodfolk. The battalion was designated as "Separate Battalion of West Tennessee Militia". This battalion was based at Fort Jackson most of the time from late November 1814 to early 1815. Some of the men were stationed at Fort Decatur, where the remnants of the defeated Creek Nation came to surrender, seeking food and supplies (surrendering Creeks also went to Fort Jackson). One company, under Captain Abner Pearce, was stationed at Fort Montgomery. Woodfolk was a wealthy land speculator who owned a large plantation in Jackson County. In addition to potentially sharing time with Davy Crockett, during this military service James Clinton Neill may well have also met his future Texas Revolution commander, Sam Houston.
