We learn from the Mississippi! that on the 51st of July, two or three hours before flay, a party of from 80 to 100 Sacs and Fox Indians, surprised a Menominee Camp, 3 or 400 yards above old Fort Craw fold, on the east ride of the Mississippi, and killed twenty-five of the latter, and wounded many, who may probably recover. There were about thirty or forty Mcnominees, men, women and children in the camp, most of whom were drunk, and the women had concealed their guns and knives to prevent their hurting each other.The Sacs and Foxes, though greatly superior in numbers and attacking by surprise a drunken and.unarmed encampment, lost several men, who were seen4o fall in the onset, and ^•treated in less than ten minutes with only a lew scalps, pursued-by four or five Menomi-nees, who fired upon them until they were half a mile below the village.The party killed, consisted of one w ar chief, ih; *c head men, four warriors, six women and eleven children.This massacre of the Menominee* is a mostaudacious aggression, not only against the unfortunate sufferers, but against the authority of the United States. The Menominees were on a visit to our post at Prairie du Chien,— were sleeping under the flag of the United States, and almost under the guns of the fort. The assailing party crossed from the west bank of the Mississippi and made their attack in defiance of the power which has hitherto, in a great degree, been enabled to hold in check, the fierce tribes even when at a dis-tance from the military posts. The violence pr] recently committed within the very precincts ed of the national authority, will require the in- StT ferposition of the arm of the. government, that an example may be made by bringing the mur- nit derers to justice. bacon?veriCla-■staksertandExttheoccibyHebreterjtanant]havrulThrui! bid on the betdUwacitTh8tfcaiNconlwhKt
