Final answer:
American native leader Sitting Bull referred to sharpshooter Annie Oakley as "Little Sure Shot." He was a Lakota Sioux spiritual leader known for his role in the Battle of Little Bighorn against U.S. forces led by George Custer.
Step-by-step explanation:
The person whom American native leader Sitting Bull supposedly referred to as "Little Sure Shot" was Annie Oakley, a sharpshooter and exhibition shooter whose skill with a rifle won her fame in Buffalo Bill's Wild West show. Sitting Bull himself, known for his leadership and resistance during the westward expansion of the United States, was a spiritual leader of the Lakota Sioux and played a significant role in the Battle of Little Bighorn.
During the Battle of Little Bighorn, Sitting Bull united multiple tribes to resist forced removal from their lands and led a notable victory against the U.S forces under Colonel George Custer. Sitting Bull's leadership and strategic acumen were instrumental in the success of this encounter, marking one of the most famous events in the American West.
After the battle, and despite the eventual suppression of Native American resistance, Sitting Bull fled to Canada and later returned to the United States where he even briefly worked in Buffalo Bill's Wild West show—the same show where Annie Oakley, dubbed "Little Sure Shot" by Sitting Bull, performed her famous marksmanship.
