"Drive them, Mason, but look out for the main ridge," is the only order we hear; and, without a word, shout, or shot, "K" goes squarely at the foe. They fire wildly, wheeling about and backing off towards the hills; but our men waste no shot, and we speed up the slope, spreading out unconsciously in open order to right and left. Their bullets whistle harmlessly over our heads, and some of our young men are eagerly looking for permission to begin. Now the pursued have opened fire from both our flanks, for we have spread them open in our rush; and, glancing over my shoulder, it is glorious to see Montgomery's beautiful grays sweeping to our right and rear, while Kellogg's men are coming "front into line" at the gallop on our left. We gain the crest only to find the Indians scattering like chaff before us, utterly confounded at their unexpected encounter. Then comes the pursuit--a lively gallop over rolling prairie, the Indians dropping blankets, rations, everything weighty they could spare except their guns and ammunition. Right and left, far and near, they scatter into small bands, and go tearing homeward. Once within the limits of the reservation they are safe, and we strain every nerve to catch them; but when the sun is high in the heavens and noon has come, the Cheyennes are back under the sheltering wing of the Indian Bureau, and not one of them can we lay hands on. Baffled and astounded, for once in a lifetime beaten at their own game, their project of joining Sitting Bull nipped in the bud, they mourn the loss of three of their best braves slain in sudden attack, and of all their provender and supplies lost in hurried flight. Weary enough we reach the agency building at seven that evening, disappointed at having bagged no greater game; but our chief is satisfied. Buffalo Bill is radiant; his are the honors of the day; and the Fifth generally goes to sleep on the ground, well content with the affair on the War Bonnet. CHAPTER IV. THE MARCH TO THE BIG HORN.
