With Creek Indians as British allies and Cherokees loyal to U. S., in War of 1812, it was expedient to locate a fort at Standing Peach tree on the Chattahoochee - the boundary line.
Lt. Geo. Gilmer (later, twice Governor of Georgia) was sent here (1814) with a small force to erect a fort and protect workmen building flat boats for shipping supplies to Fort Mitchell.
Lt. Gilmer´s fort was built on the knoll north of and at the month of Peachtree Creek. J. McC. Montgomery, Superintendent of Artificers, set up the boat-yard in the flat area south of the creek - a bridge connecting it with the fort. Montgomery returned to this vicinity as a resident about 1821.
