In the spring of 1971, radicals, hippies, and veterans gathered to protest the war in Vietnam by blockading the nation's capital. Drawing on interviews, archives, and newfound White House transcripts, Lawrence Roberts re-creates these largely forgotten events through the eyes of such figures as John Kerry, Jane Fonda, and Daniel Ellsberg, leaker of the Pentagon Papers. To prevent the Mayday Tribe's guerrilla-style traffic blockade, the government mustered the military, arresting more than 12,000 people. As Roberts argues here, a paranoid Richard Nixon had just embarked on the road to the Watergate scandal and the implosion of the presidency.
