On October 21, 1967, a diverse coalition of 100,000 people, including students, clergy, celebrities and countercultural figures, rally at the Lincoln Memorial in Washington, D.C., for one of the first major national protests against the Vietnam War. The event includes speeches and musical performances.

Half of the crowd marches across the Potomac River to the Pentagon, where U.S. Army paratroopers are standing guard. Television cameras record the tense stand-off — as well as some lighter moments: activist Abbie Hoffman leads a group attempting to psychically levitate the Pentagon.

Some protestors attempt to enter the building provoking a forceful response including tear gas. Over 600 people are arrested. The crowd is dispersed after midnight.
