For several years past the government of the United States, as is well known, has been engaged in removing the Indian tribes, resident within the States, to tracts of wild but fertile land, situated beyond the verge of white population. Some of the tribes thus removed, however, when they came to hunt over the lands assigned them, encountered fierce opposition from the aboriginal tribes of the prairies, who claimed the country as their own, and denied the right of the United States to make the transfer. The migratory tribes were thus placed in a disastrous predicament: having sold their native lands to the United States, they had no place to which they might retreat; while they could only maintain a footing in their new homes, by incessant fighting. The government of the United States hastened to put an end to the bloody conflicts thus engendered, by purchasing the contested lands, and effecting treaties of peace between the jarring tribes. In some instances, however, the aboriginals remained unappeased. This especially was the case, with a fierce and numerous tribe of Pawnees, inhabiting the banks of the Platte river, and who were backed in their hostilities by their allies the Otoes, who, though less numerous, were even more daring than themselves. These two tribes laid claim to all the land lying between the Platte and Kanzas rivers; a region comprising several hundred square miles. It had long been their favourite hunting ground, in which it was death for a strange hunter to intrude. This forbidden tract, however, had been granted by the United States to the Delawares; and the latter had made it the scene of their hunting excursions. A bitter feud was the consequence. The tract in question became a debateable ground in which war parties were continually lurking. The Delawares had been attacked, while hunting, by the Pawnees, and many of their tribe had fallen. The Delawares, in revenge, had surprised and burnt one of the Pawnee towns, while the warriors were absent on a buffalo hunt. The hostile feelings, thus awakened among the aboriginal tribes of the prairies, had been manifested toward the white men. Several trappers and traders had been massacred by the Pawnees, who looked upon them as intruders; and who were too far from the settlements, too confident of their own prowess, and too ignorant of the power of the whites, to care much either for their friendship or their enmity.
