On September 9, 1980, Daniel Berrigan, his brother Philip, and six others (the “Plowshares Eight”) began the ”Plowshares Movement” when they entered the General Electric Nuclear Missile Re-entry Division in King of Prussia, Pennsylvania where nose cones for the Mark 12A warheads were made. They hammered on two nose cones, poured blood on documents and offered prayers for peace. They were arrested and initially charged with over ten different felony and misdemeanor counts. On April 10 1990, after nearly ten years of trials and appeals, the Plowshares Eight were re-sentenced and paroled for up to 23 and 1/2 months in consideration of time already served in prison.

Since this action over seventy Plowshares actions have taken place around the world against weapons of war, several involving Berrigan himself.
