On the fourth day of our march, we discovered many fresh signs of buffaloes; and at last, immense herds of them grazing on the distant hills. Indian trails were daily growing fresh, and their smokes were seen in various directions ahead of us. And on the same day at noon, we discovered a large party at several miles distance, sitting on their horses and looking at us. From the glistening of the blades of their lances, which were blazing as they turned them in the sun, it was at first thought that they were Mexican cavalry, who might have been apprized of our approach into their country, and had advanced to contest the point with us. On drawing a little nearer, however, and scanning them closer with our spy-glasses, they were soon ascertained to be a war-party of Camanchees, on the look out for their enemies. The regiment was called to a halt, and the requisite preparations made and orders issued, we advanced in a direct line towards them until we had approached to within two or three miles of them, when they suddenly disappeared over the hill, and soon after shewed themselves on another mound farther off and in a different direction. The course of the regiment was then changed, and another advance towards them was commenced, and as before, they disappeared and shewed themselves in another direction. After several such efforts which proved ineffectual, Col. Dodge ordered the command to halt, while he rode forward with a few of his staff, and an ensign carrying a white flag. I joined this advance, and the Indians stood their ground until we had come within half a mile of them, and could distinctly observe all their numbers and movements. We then came to a halt, and the white flag was sent a little in advance, and waved as a signal for them to approach; at which one of their party galloped out in advance of the war-party, on a milk white horse, carrying a piece of white buffalo skin on the point of his long lance in reply to our flag. This moment was the commencement of one of the most thrilling and beautiful scenes I ever witnessed. All eyes, both from his own party and ours, were fixed upon the manœuvres of this gallant little fellow, and he well knew it.
