"Sir: Your letter of the 10th instant is received, and I take pleasure in saying to you that it affords the department much satisfaction to perceive the conclusion to which you have arrived as to your brevet rights. None will do you the injustice to suppose that the opinions declared by you upon this subject are not the result of reflections and convictions; but since the constituted authorities of the Government have, with the best feelings entertained, come to conclusions adverse to your own, no other opinion was cherished or was hoped for but that, on your return to the United States, you would adopt the course your letter indicates, and with good feelings resume those duties of which she has so long had the benefit. Agreeably to your request, the furlough heretofore granted you is revoked from and after the 20th instant. You will accordingly report to the commanding general, Alexander Macomb, for duty.
J.H. Eaton.
"To Major-General Winfield Scott."
General Scott, on reporting to General Macomb, was assigned to the command of the Eastern Department, while General Gaines was assigned to the Western. From the assignment of General Scott to the command of the Eastern Department, for a period of nearly three years, his duties were those of an ordinary department commander, with no incidents necessary to be ingrafted into his biography.
A treaty had been made by the United States Government in 1804 with the chiefs of the Sac Indians, in which their lands east of the Mississippi were ceded to the Government, but with the reservation that so long as they belonged to the Government of the United States the Indians should have the privilege of occupying and hunting on them. The Sacs and Foxes were contiguous and friendly tribes, and their principal village was on a peninsula between the Rock River and the Mississippi. Their principal chief was known as Black Hawk. The United States Government in its treaty acquiring the title to these Indian lands made a guarantee that the Indians should be free from intrusion from any white settlers.
Their lands were very fertile, and soon white men in large numbers began to encroach on them, and no adequate steps were taken by the Government to protect the Indians in their treaty rights. In 1829 the Government ordered a public sale of lands which included a part of the Sac village. It was purchased by an Indian trader. This greatly disturbed the Chief Black Hawk, but he was assured that if the lands purchased by this agent had not actually been sold to the Government that the sale would be canceled and the Indian occupants allowed to remain. Nothing more was done in the matter until in the spring of 1831, when the corn planted by a number of Indians was plowed up by white settlers, and many annoying trespasses made by the whites upon the Indian occupants. The Chief Black Hawk then announced to the white settlers in the village that they must remove. This resulted in a memorial from some of the white settlers, in May, 1831, to the Governor of Illinois, stating that the Indians were committing depredations on them. The Governor called out seven hundred militia to remove a band of the Sac Indians, and so notified General Gaines. General Gaines, on May 29th, replied to the Governor that he had ordered six companies of troops from Jefferson City to Rock Island, and four other companies from Prairie du Chien, to assist the Governor's militia in repelling the Indians. When the United States troops reached Fort Armstrong a conference was held with some of the Indian chiefs, but with no practical results. On receiving this information General Gaines called on the Governor of Illinois for additional forces, and on June 25th Governor Reynolds and General Joseph Duncan arrived at Rock River with sixteen hundred mounted militia. The Indians from the Sac village, being informed of this movement, deserted their homes with their wives and children and crossed the Mississippi. The next morning General Gaines occupied the Sac village without opposition.
A treaty was then made (June 30th) by General Gaines and Governor Reynolds with the Sacs, by which the Indians agreed to take up their abode west of the Mississippi River. In April, 1832, Chief Black Hawk and his tribe recrossed the Mississippi, in violation of the treaty previously made, for the purpose of joining the Winnebagoes and making a crop of corn and beans.
General Henry Atkinson at this time was in command of Fort Armstrong. He notified Black Hawk that he must recross the river or be driven back. The Indians refused to obey the order. Black Hawk endeavored to enlist some of the Northwestern tribes to join him, but failing to gain their assent, resolved to recross the Mississippi. He was encamped with his tribe at a place which the Indians called Kish-wa-cokee.
Some of the Illinois mounted militia were at Dixon's Ferry, on Rock River, not far from the Indian encampment. Major Stillman, commanding some three hundred volunteers, moved from Dixon's Ferry to Sycamore Creek on a scouting expedition. Black Hawk, being apprised of their approach, sent three of his young Indians bearing a white flag to meet them. One of these young Indians was captured and killed. Another party of five Indians, following the flag-of-truce bearers to assist in pacific negotiations, were met by the whites and two of them killed. The Illinois militia moved on and crossed Sycamore Creek. Black Hawk, who was exasperated at the killing of his men whom he had sent under flag of truce, advanced with his warriors on May 14th, met the Illinois militia, engaged and defeated them, and forced them to recross the creek.
This success greatly encouraged the Indians, but created great alarm and excitement with the white people of Illinois. Many small battles took place after this between the whites and Indians, and the war was brought to a close by the delivery of Black Hawk to the Indian agent, General Street, August 27th, by two of his followers who betrayed him. This war created necessarily great excitement and alarm in Illinois. It was the general expectation that the Winnebagoes and Pottawattomies would sympathize with Black Hawk, and the result would be a general Indian war. At this juncture General Scott was ordered to proceed to Illinois and take command of the forces to bring the Indians into subjugation. In July, acting under this order, he left Buffalo with about one thousand troops, destined for Chicago. The general and his staff, with about two hundred and twenty men, embarked on the steamboat Sheldon Thompson, and on July 8th it was announced that several of the soldiers were attacked with Asiatic cholera. The vessel arrived at the village of Chicago on the 10th with eighty sick men on board, one officer and fifty-one soldiers having died during the passage.
