“The pacification of July, 1830, has been violated under the guns of Fort Crawford, and if some immediate course is not taken to chastise those violators of that solemn arrangement, the influence of the officers of the United States will be destroyed and the power of the Government disregarded by the Indians. “Respectfully, etc., etc., “JOS. M. STREET, Indian Agent. “GEN. WILLIAM CLARK, Superintendent of Indian Affairs at St. Louis.” “U.S. Indian Agency at Prairie du Chien, July 31, 1831, 7 o’clock A.M. “Sir:–After a personal inspection of the scene of massacre, I hasten to inform you that last night the Sacs and Foxes struck the Menominees, encamped on the east side of the Mississippi, about three or four hundred paces above old Fort Crawford, and killed twenty-four[88] of the latter, butchering them in a most shocking manner. “The Sacs and Foxes came up and left their canoes just above the old fort and completely surprised the Menominees, who, under the sanction of the peace of 1830 at this place, and their vicinity to the fort, were unsuspicious of danger. “The attack was made about two hours before daylight, and the assailants were gone before light. “So daring a violation of the treaty of July, 1830, made at this village, and within cannon shot of the fort, evinces a spirit little in accordance with its humane and pacific object. “I am also this moment informed that runners will be immediately dispatched by the Menominees to Green Bay and to the Sioux. “I shall be at Judge Lockwood’s during the day. “Respectfully yours, etc., “JOSEPH M. STREET, U.S. Indian Agent. “To CAPT. G. LOOMIS; Commanding Fort Crawford.” “Superintendency of Indian Affairs, “St. Louis, Sept. 12, 1831. “Sir:–I have the honor to acknowledge the receipt of your letter of the 26th ult. on the subject of the late violation of the treaty of Prairie du Chien by the Fox Indians; and have, in accordance with your instructions, given the necessary directions to the agent at Rock Island to convene the chiefs of the Fox tribes, etc., at that place, to meet, if possible, on the 26th inst. Col. Morgan will, agreeably to the directions of Gen. Atkinson, be present at the council and will make the necessary demand of a surrender of the principal men connected with the outrage complained of; and I have reason to believe that if the requirements of the act of intercourse of 1802, as well as the stipulations of the treaty of 1825, shall be strictly complied with, it will be owing to the prompt and decisive measures pursued by the department. The result of this council shall be promptly communicated.
