During the War of 1812 a series of battles took place in the Northwest between the British and American forces and their respective Indian allies. This series of battles helped determine the control over the Wabash Valley and along with the Naval victories secured the Northwest for the Americans.
British influence and the exertions of two remarkable Indians were the causes of the next important war between the Americans and their western neighbors. The two Indians were Tecumseh, a Shawnese chief, and his brother, the Prophet, Oliwachica. These men commenced their intrigues in 1806.
After the termination of the Revolutionary War, the hardy settlers of the west had still a contest to maintain, which often threatened their extermination. The Indian tribes of the west refused to bury the hatchet when Great Britain withdrew her armies, and they continued their terrible devastation. The vicinity of the Ohio River, especially, was the scene of their operations.
