In 1843 the post was garrisoned by three troops of Dragoons and four companies of the Sixth Infantry under the command of Colonel William Davenport. Another well-known officer who was in command of the post in 1850 was General W. G. Belknap of the Fifth Infantry. Belknap and Arbuckle died in 1851. The conclusion of the Civil War returned Fort Gibson to the unimportant status to which it was reduced by its abandonment in 1857. For years, however, the large number of substantial buildings of the post were found useful from time to time. It was reoccupied in July, 1872, by two companies of the Tenth Cavalry under Colonel Benjamin H. Grierson who was sent there to cope with the lawless element attracted by the movement of the railroad camps engaged in building the Missouri, Kansas, and Texas Railroad from the Kansas line to the Red River. After the brief stay of the Tenth Cavalry a company of the Sixth Cavalry and a detachment of the Fifth Infantry were assigned to the post to help police the country, with Lieutenant Thomas M. Woodruff of the Fifth Infantry in command. They were mainly occupied in aiding the Cherokee agent in resisting the encroachment of intruding white men unlawfully seeking to settle in the Cherokee Nation. In order to maintain communication with the outside world a telegraph line was constructed to the fort from the railroad at Gibson Station. Men engaged in cutting poles for the line were crossing the Grand River on a ferry flatboat on April 20, 1874, when in the middle of the river, by awkward handling of the front guy rope, the boat was allowed to swing broadside to the current; this caused it to fill with water and sink. As a result six soldiers of the Fifth Infantry and the Sixth Cavalry and one civilian drowned. Later, in 1879, a detachment of the Twenty-second Infantry under the command of Major A. S. Hough was stationed at the post endeavoring to aid the civilian authorities in suppressing a gang of forty or fifty thieves and desperadoes that had been plundering and terrorizing the country, particularly in the Chickasaw Nation and on the Potawatomi reservation. To this duty Hough had been ordered by General Sheridan. During the Creek trouble of 1883, called the Green Peach War, part of the Twentieth Infantry was stationed at Fort Gibson and detachments were sent out to Muskogee, Eufaula, and Okmulgee to police the country. One detachment went to the Sac and Fox agency and captured several hundred Creeks who were brought to Fort Gibson where they were detained for a time and given protection from the hostile faction. The Adjutant General on August 22, 1890, issued a final order for the abandonment of the fort, directing the withdrawal of the troops and disposition of the public property there. In 1899, when the little disturbance greatly exaggerated by the name of the “Snake Uprising” caused some discussion, a company of the Ninth Infantry was for a short time stationed at the old post.
