There is hardly a trace of nervousness even among the newest comers, but this is the first chase of the campaign for us, and all are eager and excited. Horses in rear struggle to rush to the front, and as we sputter out of the sand and strike the grassy slopes beyond the timber belt all break into a lope. Two or three scouts on a ridge five hundred yards ahead are frantically signalling to us, and, bending to the left again, we sweep around towards them, now at a gallop. Mason sternly cautions some of the eager men who are pressing close behind us, and, looking back, I see Sergeant Stauffer's bronzed face lighting up with a grin I used to mark in the old Apache campaigns in Arizona, and the veteran "Kelly" riding, as usual, all over his horse, but desperately bent on being ahead when we reach the scene. Left hands firmly grasp the already foaming reins, while throughout the column carbines are "advanced" in the other. "Here comes Company 'I,' fellers," is the muttered announcement from the left and rear, and, glancing over my left shoulder, I see Kellogg with his bays and Lieutenant Reilly swinging out along the slope to our left. As we near the ridge and prepare to deploy, excitement is subdued but intense--Buffalo Bill plunging along beside us on a strawberry roan, sixteen hands high, gets a trifle of a lead, but we go tearing up the crest in a compact body, reach it, rein up, amazed and disgusted--not an Indian to be seen for two miles across the intervening "swale." Away to the left, towards the Cheyenne, scouts are again excitedly beckoning, and we move rapidly towards them, but slower now, for Mason will not abuse his horses for a wild-goose chase. Ten minutes bring us thither. Kellogg has joined forces with us, and the two companies are trotting in parallel columns. Still no Indian; but the scouts are ahead down the valley, and we follow for a brisk half-hour, and find ourselves plunging through the timber ten miles east of camp. Another hour and we are dashing along a high ridge parallel with the Black Hills, and there, sure enough, are Indians, miles ahead, and streaking it for the Powder River country as fast as their ponies can carry them. We have galloped thirty miles in a big circle before catching sight of our chase, and our horses are panting and wearied. Every now and then we pass pack-saddles with fresh agency provisions, which they had dropped in their haste. Once our scouts get near enough to exchange a shot or two, but at last they fairly beat us out of sight, and we head for home, reach camp, disgusted and empty-handed, about four p.m. Two "heavy weights" (Colonel Leib's and Lieutenant Reilly's) horses drop dead under them, and the first pursuit of the Fifth is over.
