The Osages and Pawnes.- A gentleman who arrived here a few days ago, direct from Cantonment Gibson, informs us, that just before he left, intelligence reached there of a bloody fight having taken place, a few days previous, high up the Arkansas, between two parties of Osages and Pawnees, in which the former were victorious, having killed 18 of their enemies and bore off their scalps in triumph. The Pawnees made an attack, in the first place, on a small party who were in advance of the main body of the Osages and compelled them to retreat. They however, soon rallied, pursued and overtook their enemies, whom they vanquished and compelled to retreat, after a short but bloody contest, before the main party of the Osages came up. It is said to have been one of the most desperate and hard contested engagements that has ever been fought by these two tribes. The Osages fought with guns and the Pawnees with spears and battleaxes. The loss of the Osages was 2 killed and 8 wounded. No prisoners were taken on either side.
