Answer:
False
Step-by-step explanation:
Sitting Bull and Crazy Horse were two Native American Chiefs who fought against the American settlers encroaching their land.
Both were famous for leading their people to victory against the United States army during the 1876 Battle of Little Bighorn, where they won against the United States, General George Armstrong Custer.
Hence, in this case, the correct answer is FALSE. Both Sitting Bull and Crazy Horse were two Native American Chiefs who were NOT willing to sign treaties with the U.S., agreeing to give their land away. But instead fought against them.
