And still the red leader sat at gaze, oblivious for the moment of everything around him, ignoring the coming of orders possibly from Lame Wolf himself. Suddenly the silver armlets once more gleamed on high. Then, clapping the palm of his right hand to his mouth, Red Fox gave voice to a ringing war whoop, fierce, savage and exultant, and, almost at the instant, like the boom and rumble that follows some vivid lightning flash, the prairie woke and trembled to the thunder of near a thousand hoofs. From every point of the compass--from every side, yelling like fiends of some orthodox hell, down they came--the wild warriors of the frontier in furious rush upon the silent and almost peaceful covert of this little band of brothers in the dusty garb of blue. One, two, three hundred yards they came, centering on the leafy clump of cottonwoods, riding at tearing gallop, erect, defiant, daring at the start, and giving full voice to their wild war cry. Then bending forward, then crouching low, then flattening out like hunted squirrel, for as the foremost in the dash came thundering on within good carbine range, all on a sudden the watch dogs of the little plains fort began to bark. Tiny jets of flame and smoke shot from the level of the prairie, from over dingy mounds of sand, from behind the trunks of stunted trees, from low parapet of log or leather. Then the entire grove seemed veiling itself in a drifting film of blue, the whole charging circle to crown itself with a dun cloud of dust that swept eastward over the prairie, driven by the stiff, unhampered breeze. The welkin rang with savage yell, with answering cheer, with the sputter and crackle of rifle and revolver, the loud bellow of Springfield, and then, still yelping, the feathered riders veered and circled, ever at magnificent speed, each man for himself, apparently, yet all guided and controlled by some unseen, yet acknowledged, power; and, in five minutes, save where some hapless pony lay quivering and kicking on the turf, the low ground close at hand was swept clean of horse or man. The wild attack had been made in vain. The Sioux were scampering back, convinced, but not discomfited. Some few of their number, borne away stunned and bleeding by comrade hands from underneath their stricken chargers,--some three or four, perhaps, who had dared too much,--were now closing their eyes on the last fight of their savage lives.
