Fort Davis, Oklahoma

[1][2] First called Cantonment Davis, its purposes were to help retain the loyalty of the Indian Territory to the Confederacy and to prevent Union Army invasions into Texas from the north.

[3][2][1] When complete, the fort comprised 13 wooden buildings, including barracks, a commissary, stables, and other outbuildings[1] covering an area of about eight acres, without a stockade.

[2] The post centered on a prehistoric mound that helped conceal troop activity and provided visibility of the surrounding area from its elevation.

[2][1] In 1862, Pike and his Native American troops were ordered out to support General Earl Van Dorn in northwest Arkansas.

[3][2] On December 27, 1862, Union Army troops led by Colonel William A. Phillips burned Fort Davis.
