Fort Montgomery was built in the fall of 1813 a few miles from the site of Fort Mims by Colonel Thomas Benton to serve as a supply base. General Andrew Jackson gathered a force at the fort before moving on Pensacola in November of 1814. Later, the fort was occupied by troops under Major Uriah Blue while conducting raids
against Red Sticks.

The site of Fort Montgomery is just west of Highway 59 in Baldwyn County, Alabama, about two miles southeast of Fort Mims. The site is unmarked.
