In the spring of 1830, when Black Hawk and his band returned from their annual hunt, to occupy their lodges, and prepare as usual for raising their crop of vegetables, they found, that the land in and around their village, had been brought into market, and that their old friend, the trader at Rock Island had purchased a considerable part of it. Black Hawk, greatly disturbed at this new condition of things, appealed to the agent at that place, who informed him, that the lands having been sold by government to individuals, he and his party had no longer any right to remain upon them. Black Hawk was still unwilling to assent to a removal, and in the course of the summer, he visited Malden to consult his British father on the subject, and returned by Detroit to see the great American chief, Governor Cass, residing there. Both of these persons told him that if the Indians had not sold their lands and would remain quietly upon them, they would not be disturbed. Black Hawk, acting upon the assumption that the land on which their village stood, never had been legally sold to the United States, returned home determined to keep possession of it. It was late in the fall when he arrived: his people had gone to their hunting grounds for the winter and he followed them. They made an unsuccessful hunt and the season passed off in gloom. Keokuk again exerted his influence to induce them to desert Black Hawk and remove to the Ioway. Such, however, was their attachment to their favorite village, that the whole band returned to it in the spring of 1831. The agent at Rock island forthwith notified them that if they did not remove from the land, troops would be sent by the United States to drive them off. Black Hawk says, he had a conference, about this time, with the trader at Rock Island, who enquired of him, if some terms could not be made, upon which he and his party would agree to remove to the west side of the Mississippi. To this he replied, that if his great father would do justice to them and make the proposition, they would remove. He was asked by the trader, "if the great chief at St. Louis would give six thousand dollars, to purchase provisions and other articles," if he would give up peaceably and remove. To this he agreed. The trader accordingly sent a message to the agent at St. Louis, that Black Hawk, and his whole band, could be removed for the sum of six thousand dollars, but the answer was, that nothing would be given, and that if they did not remove immediately, an armed force would be sent to compel them.

The squaws had now planted their corn, and it was beginning to grow, when the whites again commenced ploughing it up. Black Hawk at last determined to put a stop to these aggressions upon his people, and accordingly gave notice to those who were perpetrating them, that they must remove, forthwith, from his village. In the mean time, after the return of the Indians, which took place in April, eight of the white settlers united in a memorial to the Executive of the state of Illinois, in which they set forth that the Sac Indians of Rock river had "threatened to kill them; that they had acted in a most outrageous manner; threw down their fences, turned horses into their corn-fields, stole their potatoes, saying the land was theirs and that they had not sold it,—although said deponents had purchased the land of the United States' government: levelled deadly weapons at the citizens, and on some occasions hurt said citizens for attempting to prevent the destruction of their property," &c. &c. The memorial concludes with the still more startling outrage, that the said Indians went "to a house, rolled out a barrel of whiskey and destroyed it." One of these eight afflicted memorialists, swore the other seven to the truth of their statements, and with an earnest prayer for immediate relief, it was placed before his Excellency, on the 19th of May.

This long catalogue of outrages, backed by other memorials, and divers rumors of border depredations, committed by "General Black Hawk" and his "British Band," called into immediate action the patriotism and official power of the Governor. Under date of Bellville, May 26, 1831, he writes to the superintendent of Indian affairs, General William Clark, at St. Louis, that in order to protect the citizens of Illinois, which he considered in a state of "actual invasion," he had called out seven hundred militia to remove a band of Sac Indians, then residing at Rock river, and he pledges himself to the superintendent, that in fifteen days he will have a force in the field, sufficient to "remove them dead or alive, over to the west side of the Mississippi." But to save all this disagreeable business, his Excellency suggests to General Clark that perhaps a request from him to these Indians, to remove to the west side of the river, would effect the object of procuring peace to the citizens of the state. The letter concludes with the magnanimous declaration that there is no disposition on the part of the people of the state of Illinois to injure these unfortunate, deluded savages, "if they will let us alone."

General Clark, under date of St. Louis, 28 May, 1831, acknowledges the receipt of the above letter, and says, that he had already made every effort in his power, to get all the Indians who had ceded their lands to remove.

On the same day, 28th May, 1831, Governor Reynolds writes to General Gaines, then at St. Louis, that he had received information that Black Hawk and his band had invaded the state of Illinois; and that he had called out seven hundred troops to meet them. General Gaines, on the 29th of May, replies to his Excellency that he had ordered six companies of United States troops from Jefferson Barracks to Rock Island, and that they would be joined by four other companies from Prairie des Chiens, making in all ten companies; a force which he deemed sufficient to repel the invasion and give security to the frontier: That if the residue of the Sacs and Foxes, or other tribes should unite with the band of Black Hawk, he would call on his Excellency for some militia, but did not then deem it necessary.

On the 30th of May, the troops, accompanied by General Gaines, left Jefferson barracks, in a steam boat, for Fort Armstrong; and upon the 7th of June, the commanding general held a council on Rock island, at which Black Hawk and some of his braves were present. Keokuk, Wa-pel-lo and other chiefs from the west side of the Mississippi were also in attendance. When the council was opened, General Gaines rose and stated that the President was displeased with the refusal of the Sacs of Rock river, to go to the right bank of the Mississippi, that their great father wanted only that which was reasonable and right, and insisted that they should remove. Black Hawk replied, in substance, that the Sacs had never sold their lands and were determined to hold on to their village. General Gaines inquired, "who is Black Hawk? Is he a chief? By what right does he appear in council?"

No reply was made; Black Hawk arose, gathered his blanket around him, and stalked out of the council room. On the following morning he was again in his seat, and when the council was opened, he arose and said, "My father, you inquired yesterday, "who is Black Hawk? why does he sit among the chiefs?" I will tell you who I am. I am a Sac, my father was a Sac—I am a warrior and so was my father. Ask those young men, who have followed me to battle, and they will tell you who Black Hawk is—provoke our people to war, and you will learn who Black Hawk is." He then sat down, and nothing more was said on the subject. The result of this conference was, that Black Hawk refused to leave his village, and that General Gaines informed him and his party, if they were not on the West side of the Mississippi within a few days, he should be compelled to remove them by force. The General anxious, if possible, to effect the object without bloodshed, deemed it expedient to increase his forces, that the Indians might be intimidated, and thus induced to submit; or, in case of a resort to hostile measures, that he might be fully prepared to act with efficiency. He accordingly called upon the Governor of Illinois for some militia, to co-operate with the United States' troops under his command. On the 25th of June, Governor Reynolds, and General Joseph Duncan with 1600 mounted militiamen, principally volunteers, reached Rock river. On the morning of the 26th, General Gaines with his combined forces, took possession of the Sac village without firing a gun or finding an Indian; the whole party, with their wives and children, having crossed over the Mississippi the previous night. On the following day they were found on the west bank of that stream, encamped under the protection of a white flag.

On the 30th of June, General Gaines and Governor Reynolds signed a treaty of capitulation and peace, with Black Hawk, Pa-she-pa-how, Wee-sheat, Kah-ke-ka-mah, and other chiefs and head men of the British band of Sac Indians, and their old allies of the Winnebago, Pottawatamie and Kickapoo nations. The preamble to this treaty is worthy of preservation. It is in these words.

"Whereas, the 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 year 1804, 1816 and 1825, continued to remain upon and to cultivate the lands on Rock river, ceded to the United States by 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 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, destroy their corn, and invite many of their old friends of the Pottawatamies, 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 nothing could have restrained them, but the apprehension 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." Therefore, &c.

The first article stipulates that peace is granted by the United States to the British Band of Sac Indians—the second that they are required to submit to the chiefs of the Sac and Fox nations, who reside on the west side of the Mississippi—the third that the United States guaranty to them the integrity of their lands west of that river under the treaties of 1825 and 1830—the fourth that the said British Band shall not trade with any nation but the United States—that the United States have a right to establish military posts and roads within their country—the sixth that the chiefs and head men of the Sac and Fox nations shall enforce the provisions of this treaty—and finally that permanent peace and friendship be established between the United States and the said British Band of Sac Indians, and that the latter are not to return to the east side of the Mississippi without the permission of the former.
