In 1819, Lewis Cass, in the Treaty of Saginaw, negotiated the prerogative for the United States to own and settle the area with the leaders of the Ojibwe. In 1820, Campau attempted to expand across to the east bank of the river but was rejected by the Chippewas. In 1822, the United States Army established a fort on the west bank of the Saginaw River and named it Fort Saginaw. Two companies were stationed at the fort. A group of investors purchased some land near the fort and had it platted under the name, Town of Sagana. Due to the extremely harsh seasons and illnesses, Fort Saginaw was abandoned by 1824.
