Input: Question: Which tribe was Chief Blackfish the Chief of? Passage:Little documentary evidence of Black Hoof's life appears in the historical record before 1795. As a child he may have been a member of a waundering band of some 400 Shawnees led by Peter Chartier between 1745 and 1748, who founded the community in Kentucky called Eskippakithiki and later moved to Sylacauga, Alabama, eventually settling in Old Shawneetown, Illinois. He probably took part in the Battle of Point Pleasant during Lord Dunmore's War against the Virginia militia in 1774. During the American Revolutionary War, he may have taken part in the siege of Boonesborough in 1778, which was led by Chief Blackfish, as well as the subsequent defense of the Shawnee village of Chillicothe in 1779. In the Northwest Indian War, Black Hoof was defeated by "Mad" Anthony Wayne and, following the collapse of the Indian confederation, surrendered in 1795.
