"There is a prospect, I think, that the Indian department in this part of the country will soon require efficient officers. There is little doubt that there will be a general and sanguinary war among the Indians in the spring. The outrages of the Sauks and Foxes, can be endured no longer. Within a short time, they have cut off the head of a young Munomonee Indian, at the mouth of Winconscin river--killed a Winnebago woman and boy, of the family of Dekaree, and a Sioux called Dixon. The whole Sioux nation have made arrangements for a general and simultaneous attack on the Foxes; the Winnebagoes, and probably the Munomonees will join them." "Little Rock, Ark. Ter. Feb. 5. "_Murderous Battle._--A gentleman who arrived here yesterday, direct from the Western Creek agency, informs us that a war party of Osages returned just before he left the agency, from a successful expedition against the Pawnee Indians. He was informed by one of the chiefs, that the party seized a Pawnee village, high up on the Arkansas, and had surrounded it before the inmates were apprised of their approach. At first the Pawnees showed a disposition to resist; but finding themselves greatly outnumbered by their assailants, soon sallied forth from their village, and took refuge on the margin of a lake, where they again made a stand. Here they were again hemmed in by the Osages, who throwing away their guns, fell upon them with their knives and tomahawks, and did not cease the work of butchery as long as any remained to resist them. Not one escaped. All were slain, save a few who were taken prisoners, and who are perhaps destined to suffer a more cruel death than those who were butchered on the spot. Our informant did not learn what number of Pawnees were killed, but understood that the Osages brought in sixty or seventy scalps, besides several prisoners. "We also learn, that the Osages are so much elated with this victory, that another war party were preparing to go on an expedition against some Choctaws who reside on Red river, with whom they have been at variance for some time past." _Extract of a Letter from an Officer of the Army, dated Prairie du Chien._ [FROM THE NEW YORK COM.
