Reveille and the dawn of the seventh come together. We wake stiff and cold in the keen morning air, but thaw out rapidly under the genial influence of the huge tins of coffee promptly supplied. At six we descry the infantry and the pack trains clambering up the heights to the northwest and disappearing from view over the timbered crests. At seven we again mount and ride down stream a few hundred yards, then turn sharp to the left and up a broad winding ravine along a beaten trail--buffalo and Indian, of great antiquity. Mile after mile we push along up grade--we of the Fifth well to the front to-day and in view of the scouts and advance most of the time. The woods are thick along the slopes, the grass that was rich and abundant in the valley of the Tongue is becoming sparse. Up we go--the ascent seems interminable. Once in a while we catch glimpses of smoke masses overhead and drifting across the face of distant ridges. At last we see knots of horsemen gathering on a high ridge a mile in front; half an hour's active climbing, mostly afoot and leading our horses, brings us close under them. "Halt" is sounded, and General Carr and I go up to join the party on the crest. We pause on the very summit of the great divide between the Tongue and the Rosebud, and far to south, north, and west the tumbling sea of ravine and upland, valleys that dip out of sight, mountains that are lost in fleecy clouds, all are spread before us. The view is glorious. We look right down into the cañon of the Rosebud, yet it must be six to eight miles away, and how far down we cannot judge. From every valley north and west rolling clouds of smoke rise towards and blacken the heavens. Somewhere over on those opposite bluffs General Crook had his big fight with the Sioux on the 17th of June, but not a Sioux is in sight. It takes us three good hours to get down into the valley, and here we receive in grim silence the orders to go into bivouac parallel to the stream, facing west. The Indians have burned off every blade of grass their ponies left undevoured along the narrow gorge, and for miles below us the scouts report it even worse. "The whole Sioux nation has been in camp hereabouts not two weeks ago," says one rugged frontiersman, "and I've been nigh onto ten mile down stream and didn't reach the end of the village." The ground is strewn with abandoned lodge-poles, and covered with relics of Indian occupancy too unmistakable to be pleasant. The Third and Second Cavalry file into position on the eastern bank parallel with our line, and all the pickets go out at once--Captain Hayes, with Company "G," covering our front.
