Federal troops reoccupied Fort Duncan on 23 March 1868 by the 41st Infantry under the command of Lt. Col. William R. Shafter, and Lt. Henry Ware Lawton as quartermaster. An additional unit of Buffalo soldiers stationed at the fort, besides the 41st, was the 9th Cavalry. This included George B. Jackson, later a businessman in San Angelo called "the wealthiest black man in Texas" during the second half of the 19th century. The 25th Infantry arrived under the command of Major Bliss in 1870, and the Black Seminole Scouts were organized at the fort, initially under the command of 2nd Lt. Henry Field Leggett, but later commanded by 2nd Lt. John L. Bullis.
