The Time Tunnel - Season 1 - Eps 8: Massacre
The guys arrive in South Dakota in June 24, 1876, near Little Bighorn. They are captured by Indians, although Doug manages to escape and make it to Custer's camp. Custer refuses to believe Doug's tale. Meanwhile, Tony has tried to warn Sitting Bull. The Indians prepare to burn Tony at the stake, but Sitting Bull intervenes, impressed by Tony's bravery. A trial-by-combat settles the matter when Tony wins against Yellow Elk but spares his life. Tony tries to convince Sitting Bull to approach Custer peacefully, much to the disgruntlement and skepticism of Crazy Horse. Sitting Bull lets Tony go to Custer's camp with a message of peace, but Custer refuses it and locks both travellers up. They manage to escape, and are forced to watch as history plays itself out and Custer and his men are massacred.
