“A Delaware Indian prophet appeared [1762] in Michigan and preached a doctrine that he said had been revealed to him in a vision. He called for the cessation of strife by Indian against Indian, and a holy war against the Whites… finally a practical man, an Algonkian named Pontiac, arose to lead them. He formed a confederation and attacked English forts all along the Great Lakes until he was ambushed and his forces utterly defeated. …Forty years later the Shawnee Prophet … twin brother of Chief Tecumseh, repeated the promises of the Delaware Prophet… Tecumseh established the greatest Indian alliance that ever existed north of Mexico. He and his emissaries visited almost every band, tribe, and chiefdom from the headwaters of the Missouri River in the Rocky Mountains to as far south and east as Florida. Indians everywhere were arming themselves for the right moment to attack the Whites when, in 1811, Tecumseh's brother, the Shawnee Prophet, launched a premature attack at Tippecanoe… the Indians were defeated by General William Henry Harrison… Tecumseh rallied his remaining forces and joined the British in the War of 1812. He fought bravely in battle after battle, but in 1813 his 2,500 warriors from the allied tribes were defeated decisively, once again by General Harrison.”
