Forty years ago today, nine Catholic men and women - three of them priests - walked into a military draft office in Catonsville and seized the records of hundreds of young men likely to be summoned to fight in Vietnam.
They burned the papers in the parking lot, using homemade napalm to start the blaze. As the flames rose, the nine solemnly recited the Lord's Prayer and stood around waiting for the police to arrest them.
That day in the turbulent spring of 1968, the Catonsville Nine, as they became known, put the quiet Baltimore suburb on the map in a growing nationwide protest against the Vietnam War. The band of activists - whose dramatic trial drew hundreds of antiwar protesters to Baltimore that fall - inspired similar disruptions of draft offices around the country.
The Catonsville Nine also provoked an intense debate, one that has resonated across the decades as Americans challenge another unpopular war - this time in Iraq.
"I think what people are seeing is that the wars don't die," said one of group's leaders, the Rev. Daniel Berrigan, now 87 and living in New York. He and his late brother Philip, also a priest at the time, became prominent figures in the peace and social justice movements.
Some saw the fire the Nine ignited - and their subsequent imprisonment - as a courageous act of conscience, inspired by Christian faith. But others have questioned the morality - or at least the effectiveness - of vandalism, no matter how noble the cause.
Today, the Catonsville Nine are down to five. Philip Berrigan, the only member who stayed in Baltimore, died of cancer in 2002 after decades of "civil resistance," repeated arrests and imprisonment for his protests against war, militarism and social injustice.
Two others predeceased him - one in a car accident before his prison sentence was to start.
The most recent of the group to go was artist Tom Lewis, who died unexpectedly last month at his Massachusetts home, a month before a planned visit to Baltimore for a commemoration of the 1968 event.
The passion lives
But the passion for peace still burns in the survivors and their spiritual heirs as they seek to rally opposition to another war.
Elizabeth McAlister, Philip Berrigan's widow, will join a group of activists who plan to mark today's 40th anniversary with a muted protest at the annual air show at Andrews Air Force Base.
