“ARTICLES OF AGREEMENT AND CAPITULATION made and concluded this thirtieth day of June, one thousand eight hundred and thirty-one, between E.P. Gaines, Major-General of the United States Army, on the part of the United States; John Reynolds, Governor of Illinois, on the part of the State of Illinois; and the chiefs and braves of the band of Sac Indians, usually called the ‘British Band of Rock River,’ with their old allies of the Pottawatomie, Winnebago and Kickapoo nations: “WITNESSETH: That, Whereas, the said British Band of Sac Indians have, in violation of the several treaties entered into between the United States and the Sac and Fox nations in the years 1804, 1816 and 1825, continued to remain upon and to cultivate the lands on Rock River, ceded to the United States by the said treaties, after the said lands had been sold by the United States to individual citizens of Illinois, and other states. And, Whereas, the said British Band of Sac Indians, in order to sustain their pretensions to continue upon the said Rock River lands, have assumed the attitude of actual hostility towards the United States, and have had the audacity to drive citizens of the State of Illinois from their homes, to destroy their corn, and to invite many of their old friends of the Pottawatomies, Winnebagoes and Kickapoos to unite with them (the said British Band of Sacs) in war, to prevent their removal from said lands: And, Whereas, many of the most disorderly of these several tribes of Indians did actually join the said British Band of Sac Indians, prepared for war against the United States, and more particularly against the State of Illinois, from which purpose they confess that nothing could have restrained them but the appearance of force far exceeding the combined strength of the said British Band of Sac Indians, with such of their aforesaid allies as had actually joined them; but being now convinced that such a war would tend speedily to annihilate them, they have voluntarily abandoned their hostile attitude and sued for peace. “First–Peace is therefore given to them upon the following conditions, to which the said British Band of Sac Indians, with their aforesaid allies, do agree; and for the faithful execution of which the undersigned chiefs and braves of the said band, and their allies, mutually bind themselves, their heirs and assigns forever.
