One morning, when the command had just settled itself in careless repose on the short grass of the apparently interminable prairie at the first halt of the day's march, a short distance beyond Fort Larned, a strange noise, like the low muttering of thunder below the horizon, greeted the ears of the little army. All were startled by the ominous sound, unlike anything they had heard before on their dreary tour. The general ordered his scouts out to learn the cause; could it be Indians? Every eye was strained for something out of the ordinary. Even the horses of the officers and the mules of the supply-train were infected by something that seemed impending; they grew restless, stamped the earth, and vainly essayed to stampede, but were prevented by their hobbles and picket-pins. Presently one of the scouts returned from over the divide, and reported to the general that an immense herd of buffalo was tearing down toward the Trail, and from the great clouds of dust they raised, which obscured the horizon, there must have been ten thousand of them. The roar wafted to the command, and which seemed so mysterious, was made by their hoofs as they rattled over the dry prairie. The sound increased in volume rapidly, and soon a black, surging mass was discovered bearing right down on the Trail. Behind it could be seen a cavalcade of about five hundred Cheyennes, Comanches, and Kiowas, who had maddened the shaggy brutes, hoping to capture the train without an attack by forcing the frightened animals to overrun the command. Luckily, something caused the herd to open before it reached the foot of the divide, and it passed in two masses, leaving the command between, not two hundred feet from either division of the infuriated beasts. The rage of the savages was evident when they saw that their attempt to annihilate the troops had failed, and they rode off sullenly into the sand hills, as the number of soldiers was too great for them to think of charging. Cody tells of a buffalo stampede which he witnessed in his youth on the plains, when he was a wagon-master. The caravan was on its way with government stores for the military posts in the mountains, and the wagons were hauled by oxen.
