Fort Gibson

Fort Gibson is now located adjacent to the present day city of Fort Gibson, in Muskogee County Oklahoma. It is designated the Fort Gibson Historical Site. It guarded the American frontier in Indian Territory from 1824 until 1890. When constructed, the fort lay farther west than any other military post in the United States; it formed part of the north–south chain of forts intended to maintain peace on the frontier of the American West and to protect the southwestern border of the Louisiana Purchase. The fort succeeded in its peacekeeping mission for more than 50 years, as no massacres or battles occurred there.

Building the fort

Colonel Matthew Arbuckle commanded the 7th Infantry Regiment (United States) from Fort Smith, Arkansas. He moved some of his troops to establish Cantonment Gibson on 21 April 1824 on the Grand River (Oklahoma) just above its confluence with the Arkansas River. This was part of a series of forts which the United States established to protect its western border and the extensive Louisiana Purchase. The US Army named the fort for Colonel (later General) George Gibson, Commissary General of Subsistence. The post surgeon began taking meteorological observations in 1824, and the fort provided the earliest known weather records in Oklahoma. Colonel Arbuckle also established Fort Towson in southern Indian Territory. In the early years, troops constructed a stockade, barracks, other facilities, and roads. They also settled strife between the indigenous Osage Nation, which had been in the area since the seventeenth century, and the earliest bands of western Cherokee settlers.
