4. Crazy Horse
Crazy Horse was an important leader of the Oglala Lakota. He led the war against the US government for white men encroachment which disrupted their way of life. The Fetterman Massacre was one of the first skirmishes of the conflict, where he wiped out a detachment of 80 US soldiers under Captain William Fetterman, through well-planned ambush.
Crazy Horse also contributed to the decisive victory in the Battle of Little Bighorn, by tying up 1300 men led by Brigadier General George Crook, essentially leaving Custer’s 7th Cavalry at the mercy of Sitting Bull’s force. Weakened by winter and long war, Crazy Horse’s force eventually surrendered.
