Step-by-step explanation:
The statement is True. The Battle of Tippecanoe, which took place in 1811, ended Tecumseh's dream of a strong Indian confederacy to the west of the Mississippi River. The battle was fought between the forces led by General William Henry Harrison of the United States and the Native American confederacy led by Tenskwatawa, also known as the Prophet, who was the brother of Tecumseh. Although the Native Americans initially attacked the Americans, they were eventually defeated, and their defeat marked the end of their resistance against American expansion in the region.
