The trading post was discontinued after 1808, and from 1809 to 1826 the facility served as a United States military fort.
The cemetery was located about 100 yards or so southwest from the Cantonment buildings, which during the period of 1805 to 1826 had interments of at least 30–40 military officers, and about 100 enlisted soldiers.
The tombs were built of masonry, about two feet above the ground, and upon them rested the memorial tables.
[4] In 1904, newspaper stories, most notably in The St. Louis Republic, recorded the recovery and moving of 33 burials with headstones to the new Jefferson Barracks National Cemetery.
An archaeological site associated with the fort was listed on the National Register of Historic Places in 2016.
