Suddenly came other sounds than the distant drone of trumpet and tuba. Surely that was gun-firing. There could be no mistake, indeed, for punctuating the muffled roar was heard the long-drawn "wow-wow-wow" of the whooping savages. The hour had come. A mile and a half from the fort, where now stands a memorial tablet under an old cottonwood-tree in the thick of the princeliest residences of a great city, the cloud had burst. From behind the sand ridge which divided the prairie from the beach five hundred warriors had sprung suddenly to their feet, like arrows drawn to the head, and poured in a hail-storm of bullets, to which the treacherous escort added their quota. Harold had stood for some time spellbound by his own thoughts and fears, but the trance was now broken. He ran hot-foot toward the scene of the struggle. Each step brought the sights and sounds of the massacre clearer. Shrieks, yells, the rumble of the firing, dark forms leaping like madmen with uplifted arms, or bending like wild-beasts over objects on the sand. It was a tumult of horror beyond words. After a little the confusion lessened, and there was a pause, followed by the howl of triumph which is the Indian's pæan of victory. Harold, primped out by his wild run, had hidden behind a sand hill for breath, within a stone's-throw of the scene, for the savages, absorbed in their work of death, had not noticed his advancing figure. One wagon, from which now came the wail of a sick child, had escaped their fierce handiwork, and three warriors with bare tomahawks bounded toward it. The boy, taking steady aim, discharged both barrels of his rifle, and one of the red men fell. Every nerve tense with excitement, Harold sprang forward with his clubbed gun, and, catching a tomahawk cut on the barrel, dashed the butt into the head of the nearest savage. As the latter fell with closing eyes, it was with a thrill of satisfaction, strangely blended with awe, as if some higher power had struck by his hand, that the boy recognized the face of the leader of the savages who had slain his uncle and his family. The next moment he was half throttled by a clutch about his throat. "Boy my prisoner; make no noise," he heard as the iron grip loosened. It was the voice of Black Partridge, who, an unwilling actor in the tragedy, had by his craft, as afterwards turned out, saved several lives on this occasion. Mr. Kinzie, Captain Heald, and another officer, with their wives and a few others, had escaped the slaughter, and were captives. As for the rest, their mutilated bodies lay dead on the sands down to the very water's brink, where their road had been. "Perhaps not able to save Harold, for boy kill warriors," continued the friendly chief. "Better crawl through grass like Indian back to fort, and hide in cellar till dark; then swim cross to Kinzie's." So he led his charge to the edge of the rank prairie-grass with, "See Black Partridge bym-by."
