In the spring of 1808 the Pottawatomies and Kickapoos granted the two brothers and their band a tract of land on the Tippecanoe, one of the tributaries of the Wabash River in western Indiana. Here they established a village, which came to be known as the Prophet's town. They drew around them a large body of Indians from a number of tribes. The Prophet's followers now for the first time began to combine warlike sports with their religious exercises, showing that Tecumseh's genius for war was gradually predominating over the Prophet's religious fanaticism. The great plan to which Tecumseh now devoted all his genius and energies was nothing less than a mighty confederation of all the Indian tribes, to drive the white men beyond the Alleghenies. As the great scheme took shape in his mind it became less and less that of a mere temporary alliance, such as Pontiac had sought; and more and more that of a "great and permanent confederation, an empire of red men, of which Tecumseh should be the leader and Emperor." For about four years he traveled incessantly in the propagation of his enterprise. Now he visited the farthest extremity of Lake Superior. At another time he passed through the unknown regions beyond the Mississippi. Again he labored with the Creeks of the South, securing Red Eagle, or Weatherford, as his most illustrious convert. In 1810 it was reported that Tecumseh controlled more than sixteen hundred warriors. The National Government became alarmed, for it was evident that the exposed settlements of Indiana were in danger.
