The effect of Lord Dunmore's war was to make peace in the hinterland, a matter of vast importance to the Americans on the eve of the Revolution. Great Britain by the Quebec Act had placed the country north of the Ohio and extending to the Mississippi under the government of Canada. But Great Britain was soon too busy with the war in the east to pay any attention to the west, and the hinterland posts remained as they were, feebly guarded and, except for Detroit, administered by French creoles. The Indians, it is true, were friendly to the British, but the crushing defeat they had received at the hands of Lewis and the humiliating terms they were forced to make with Dunmore left them impotent. They once more began their raids, but they were incapable of concerted action; and when in 1778 George Rogers Clark, with a feeble force of less than two hundred men, advanced against the British posts at Kaskaskia and Cahokia on the Mississippi and Vincennes on the Wabash, they were unable to hinder his march. These posts fell into the hands of the Americans, and the Indians, as we shall see, were doomed. After the battle of Point Pleasant, Cheeseekau, Tecumseh's eldest brother, led his father's warriors back to the village of Piqua, where the disasters of the fight were recounted. Still covered with the stains of battle, Cheeseekau related to his mother and his awestruck brothers and sisters the manner of his brave father's death. The dark shadow of mourning fell upon the survivors. Throughout the village rose the wail of the death-song, Methoataske's voice mingling in the dirge of the widows; and so a new and tragic scene was imprinted upon the young Tecumseh's plastic mind. A father's task now fell upon Cheeseekau, who took much pride in instructing his younger brother in the art of war and in hunting, and how to endure fatigue and to perform feats of agility and daring. He gave him lessons in woodcraft and forest lore, showing him how to snare the fish, to stalk the wary deer, to guide the frail canoe through treacherous rapids, and, with tightly fastened snow-shoe, to traverse the wintry waste. Tecumseh, of course, had learned to swim almost as soon as he could walk; in running it is said that he could easily out-distance his companions; while his skill with the bow excited their admiration and envy. His greatest delight, however, was to muster his playmates into rival bands for mimic warfare.
