<P> After the early explorations, the U.S. government sought to establish control of the region, since trade along the Mississippi and Missouri rivers was still dominated by British and French traders from Canada and allied Indians, especially the Sauk and Fox . The U.S. adapted the former Spanish facility at Fort Bellefontaine as a fur trading post near St. Louis in 1804 for business with the Sauk and Fox . In 1808 two military forts with trading factories were built, Fort Osage along the Missouri River in western present - day Missouri and Fort Madison along the Upper Mississippi River in eastern present - day Iowa . With tensions increasing with Great Britain, in 1809 Fort Bellefontaine was converted to a U.S. military fort, and was used for that purpose until 1826 . </P> <P> During the War of 1812, Great Britain and allied Indians defeated U.S. forces in the Upper Mississippi; the U.S. abandoned Forts Osage and Madison, as well as several other U.S. forts built during the war, including Fort Johnson and Fort Shelby . After U.S. ownership of the region was confirmed in the Treaty of Ghent (1814), the U.S. built or expanded forts along the Mississippi and Missouri rivers, including adding to Fort Bellefontaine, and constructing Fort Armstrong (1816) and Fort Edwards (1816) in Illinois, Fort Crawford (1816) in Prairie du Chien Wisconsin, Fort Snelling (1819) in Minnesota, and Fort Atkinson (1819) in Nebraska . </P> <P> The American government used $3 million in gold as a down payment, and issued bonds for the balance to pay France for the purchase . Earlier that year, Francis Baring and Company of London had become the U.S. government's official banking agent in London . Because of this favored position, the U.S. asked the Baring firm to handle the transaction . Francis Baring's son Alexander was in Paris at the time and helped in the negotiations . Another Baring advantage was a close relationship with Hope and Company of Amsterdam . The two banking houses worked together to facilitate and underwrite the Purchase . </P> <P> Because Napoleon wanted to receive his money as quickly as possible, the two firms received the American bonds and shipped the gold to France . Napoleon used the money to finance his planned invasion of England, which never took place . </P>
