Heth saw them and led his forces to block them. The warriors broke through Heth's men, but were pursued on horseback by cavalry with Heth in the lead. They had a running fight for about five miles, which lasted several hours. At some point Heth got so far ahead of his men that he was presumed killed in action. His death was reported in newspapers around the country and he later took satisfaction in the obituaries his friends had written.

But the expedition had not come within five miles of it, and the Lakota resented this sacred peak being named after a man who had killed so many innocents.
