With the restoration of peace, therefore, it remained for the Americans to establish an effective control over the northwestern tribes. The dominance of the British trader over them must be broken, and to this end garrisons must be scattered throughout the country to overcome the tribes and give countenance to the American traders in their efforts to compete successfully with their British rivals.

How the situation was viewed by well-informed Americans may be learned from a letter written by Lewis Cass to the Secretary of War in the spring of 1816.[656] Calling attention to the indications of a renewal by the British Indian Department of its old aggressive attitude with reference to the Indians of the United States, Cass pointed out the existence of three great channels for carrying on trade between Canada and the Indians of the Mississippi and Missouri country. These were, first, by way of Chicago and the Illinois River; second, by Green Bay and the Fox-Wisconsin waterway; third, from Lake Superior to the headwaters of the Mississippi. Of these the great channel at that time was the second. Through it great quantities of goods were smuggled into the Indian country of the United States. This practice could be cut off, Cass urged, so far as the Illinois and the Fox-Wisconsin river routes were concerned, by the establishment of garrisons at Green Bay and Chicago. To stop smuggling altogether, however, there must also be a post near the Grand Portage.

Almost a year before this John Kinzie had transmitted to Cass an argument in favor of the re-establishment of a garrison at Chicago to take the place of the one that had been destroyed in the massacre of 1812.[657] Kinzie was, of course, greatly interested in the adoption of this proposal, for it would make possible the renewal by him under favorable conditions of the pursuit of a livelihood at Chicago. He pointed out that the hostility for the Americans of the tribes around Lake Michigan, between Mackinac and the southern end of the lake, was mainly due to their intercourse with the traders of the Southwest Company, who were hostile to the American traders. Because of lack of game these tribes were forced to migrate at certain seasons to the waters of the Fox, Chicago, and Illinois rivers, and as an incident to this migration they generally rendezvoused at Chicago in the spring. For this reason a garrison there was necessary to preserve order among the Indians and to restrain the British traders, whose influence would ever keep them hostile to the United States.

Before the close of the summer of 1815 the government determined not only to establish garrisons at Chicago and Green Bay, but to reoccupy Prairie du Chien and erect a new fort at Rock Island on the Mississippi, and another in the vicinity of the Falls of St. Anthony.[658] At the same time it was planned to restore the government factory at Chicago for the conduct of the Indian trade, and to establish new factories at Green Bay and Prairie du Chien.[659] To the Third Infantry under Colonel Miller, then stationed at Detroit, was allotted the duty of garrisoning the forts at Mackinac, Green Bay, and Chicago.[660] Colonel Miller with his station at Mackinac was to have command of the three posts. Two companies, Bradley's and Baker's, were destined for Chicago. In the absence of Major Baker, the ranking officer, Captain Hezekiah Bradley, commanded the detachment. The companies comprising the Green Bay contingent were ordered to embark June 9.[661] Whether the Chicago detachment accompanied them on their way does not appear, but on June 30 it was on board the schooner "General Wayne" off the "Manitoo" Island in Lake Michigan. Here the first inspection was held, and a roster of the companies was made.[662] Of the one hundred and thirty-three men enrolled in the two companies one hundred and twelve were present on this expedition.
