Fort Hoskins was garrisoned by a number of companies of soldiers throughout its short existence, and future Union Civil War Generals Christopher Columbus Augur and Phil Sheridan were stationed there. Captain Augur was assigned to Fort Hoskins as its first post commander from 25 July 1856 to 2 July 1861 and added to the records of life at the fort where he and his growing family became the first occupants of their newly constructed residence on Fort Hoskin's "Officer's Row." 2nd Lt. Phil Sheridan oversaw the construction of Fort Hoskins during this period. Two soldiers who were stationed at the fort during the American Civil War kept journals of their experiences: Royal A. Bensell and William M. Hilleary. Their accounts are of unmitigated boredom and dampness, but they provide a good picture of 19th-century life in the area.
