On the 14th September, 1815, William Clark, Ninian Edwards and Auguste Choteau, commissioners on behalf of the United States, concluded a treaty with the chiefs and warriors of the Fox tribe, by which all injuries and acts of hostility, committed by either party during the late war, were to be forgiven, and peace and friendship established between the two nations.  The fourth article of the treaty contains a recognition of the former treaty in these words.  “The said Fox tribe or nation do hereby, assent to, recognize, re-establish and confirm the treaty of St. Louis, which was concluded on the 3rd of November, 1804, to the full extent of their interest in the same, as well as all other contracts and agreements between the parties.”  This treaty was made at Portage des Sioux.

On the 13th of September, 1815, the same commissioners, at the same place, concluded a treaty of peace and friendship with the chiefs and warriors of that part of Sac nation of Indians residing on the Mississippi river.  The first article recognizes the treaty of 1804 in the following words.  “The undersigned chiefs and warriors for themselves and that portion of the Sacs which they represent, do hereby assent to the treaty between the United States of America and the united tribes of Sacs and Foxes, which was concluded at St. Louis on the third of November 1804; and they moreover promise to do all in their power to re-establish and enforce the same.”  There is a further provision that they will remain distinct and separate from the Sacs of Rock river, giving them no assistance whatever, until peace shall be established between them and the United States.  The Sacs on Rock river were that part of the tribe which had been engaged in the late war, and who now declined making a treaty with the United States, and continued, although officially notified of the peace, to commit occasional depredations on the frontiers; and, it was not until the following spring that hostilities on their part actually ceased.

On the 13th of May, 1816, the same commissioners effected a treaty with the chiefs and warriors of the Sacs of Rock river, and the adjacent country.  The first article of this treaty provides, that, “The Sacs of Rock river and the adjacent country, do hereby unconditionally assent to, recognize, re-establish and confirm the treaty between the United States of America and the united tribes of Sacs and Foxes, which was concluded at St. Louis on the 3d November 1804, as well as all other contracts and agreements, heretofore made between the Sac tribe and the United States.”  Under the 9th article of the treaty of Ghent, concluded 24th December 1814, between the United States and Great Britain, it was stipulated, that each party should put an end to Indian hostilities within their respective territory, and place the tribes on the same footing upon which they stood before the war.  Under this provision, the second article of the treaty with the Sacs of Rock river, stipulated that they are placed upon the same footing which they occupied before the late war, upon the single condition of their restoring the property stolen by them, from the whites, subsequent to their notification that peace had been made between the United States and Great Britain.
