Terror at 2:00 (12x23)

Air date: Mar 07, 1971

A racist and his henchmen steal a Gatling gun, with plans to massacre everyone -- including the Cartwrights -- involved in a peace treaty signing between the U.S. Army and the Paitues in Virginia City. The man's hope is that the tragedy will spark another war and eventually lead to the genocide of all Native Americans.
