Was Custer wiped out by a “Mysterious Renegade”?

 

In his book, Son of the Morning Star: Custer and the Little Bighorn , Evan S. Connell tells us

 “News of the Little Bighorn calamity was at first discredited.  Americans could not believe that Sitting Bull had defeated General Custer….they refused to admit that an uneducated savage could have defeated a West Point graduate.  Therefore such a genius must be … a disguised renegade.  So it was alleged that a mysterious swarthy youth from the Great Plains, nicknamed “Bison”, had attended West Point and there absorbed the military science that laid General Custer low.” (Connell, 223)
