A remarkable change in sentiment took place. In early 1965, when the bombing of North Vietnam began, a hundred people gathered on the Boston Common to voice their indignation. On October 15, 1969, the number of people assembled on the Boston Common to protest the war was 100,000. Perhaps 2 million people across the nation gathered that day in towns and villages that had never seen an antiwar meeting.

In the summer of 1965, a few hundred people had gathered in Washington to march in protest against the war: the first in line, historian Staughton Lynd, SNCC organizer Bob Moses, and long- time pacifist David Dellinger, were splattered with red paint by hecklers. But by 1970, the Washington peace rallies were drawing hundreds of thousands of people. In 1971, twenty thousand came to Washington to commit civil disobedience, trying to tie up Washington traffic to express their revulsion against the killing still going on in Vietnam. Fourteen thousand of them were arrested, the largest mass arrest in American history.

Hundreds of volunteers in the Peace Corps spoke out against the war. In Chile, ninety-two volunteers defied the Peace Corps director and issued a circular denouncing the war. Eight hundred former members of the Corps issued a statement of protest against what was happening in Vietnam.

The poet Robert Lowell, invited to a White House function, refused to come. Arthur Miller, also invited, sent a telegram to the White House: "When the guns boom, the arts die." Singer Eartha Kitt was invited to a luncheon on the White House lawn and shocked all those present by speaking out, in the presence of the President's wife, against the war. A teenager, called to the White House to accept a prize, came and criticized the war. In Hollywood, local artists erected a 60-foot Tower of Protest on Sunset Boulevard. At the National Book Award ceremonies in New York, fifty authors and publishers walked out on a speech by Vice-President Humphrey in a display of anger at his role in the war.

In London, two young Americans gate-crashed the American ambassador's elegant Fourth of July reception and called out a toast: "To all the dead and dying in Vietnam." They were carried out by guards. In the Pacific Ocean, two young American seamen hijacked an American munitions ship to divert its load of bombs from airbases in Thailand. For four days they took command of the ship and its crew, taking amphetamine pills to stay awake until the ship reached Cambodian waters. The Associated Press reported in late 1972, from "York, Pennsylvania: "Five antiwar activists were arrested by the state police today for allegedly sabotaging railroad equipment near a factory that makes bomb casings used in the Vietnam war."

Middle-class and professional people unaccustomed to activism began to speak up. In May 1970, the New York Times reported from Washington: "1000 'ESTABLISHMENT' LAWYERS JOIN WAR PROTEST." Corporations began to wonder whether the war was going to hurt their long- range business interests; the Wall Street Journal began criticizing the continuation of the war. As the war became more and more unpopular, people in or close to the government began to break out of the circle of assent. The most dramatic instance was the case of Daniel Ellsberg.

Ellsberg was a Harvard-trained economist, a former marine officer, employed by the RAND Corporation, which did special, often secret research for the U.S. government. Ellsberg helped write the Department of Defense history of the war in Vietnam, and then decided to make the top- secret document public, with the aid of his friend, Anthony Russo, a former RAND Corporation man. The two had met in Saigon, where both had been affected, in different experiences, by direct sight of the war, and had become powerfully indignant at what the United States was doing to the people of Vietnam.

Ellsberg and Russo spent night after night, after hours, at a friend's advertising agency, duplicating the 7,000-page document. Then Ellsberg gave copies to various Congressmen and to the New York Times. In June 1971 the Times began printing selections from what came to be known as the Pentagon Papers. It created a national sensation.

The Nixon administration tried to get the Supreme Court to stop further publication, but the Court said this was "prior restraint" of the freedom of the press and thus unconstitutional The government then indicted Ellsberg and Russo for violating the Espionage Act by releasing classified documents to unauthorized people; they faced long terms in prison if convicted. The judge, however, called off the trial during the jury deliberations, because the Watergate events unfolding at the time revealed unfair practices by the prosecution.

Ellsberg, by his bold act, had broken with the usual tactic of dissidents inside the government who bided their time and kept their opinions to themselves, hoping for small changes in policy. A colleague urged him not to leave the government because there he had "access," saying, "Don't cut yourself off. Don't cut your throat." Ellsberg replied: "Life exists outside the Executive Branch."

The antiwar movement, early in its growth, found a strange, new constituency: priests and nuns of the Catholic Church. Some of them had been aroused by the civil rights movement, others by their experiences in Latin America, where they saw poverty and injustice under governments supported by the United States. In the fall of 1967, Father Philip Berrigan (a Josephite priest who was a veteran of World War II), joined by artist Tom Lewis and friends David Eberhardt and James Mengel, went to the office of a draft board in Baltimore, Maryland, drenched the draft records with blood, and waited to be arrested. They were put on trial and sentenced to prison terms of two to six years.

The following May, Philip Berrigan-out on bail in the Baltimore case-was joined in a second action by his brother Daniel, a Jesuit priest who had visited North Vietnam and seen the effects of U.S. bombing. They and seven other people went into a draft board office in Catonsville, Maryland, removed records, and set them afire outside in the presence of reporters and onlookers. They were convicted and sentenced to prison, and became famous as the "Catonsville Nine." Dan Berrigan wrote a «Meditation» at the time of the Catonsville incident:

Our apologies, good friends, for the fracture of good order, the burning of paper instead of children, the angering of the orderlies in the front parlor of the charnel house. We could not, so help us God, do otherwise… We say: killing is disorder, life and gentleness and community and unselfishness is the only order we recognize. For the sake of that order, we risk our liberty, our good name. The time is past when good men can remain silent, when obedience can segregate men from public risk, when the poor can die without defense.

When his appeals had been exhausted, and he was supposed to go to prison, Daniel Berrigan disappeared. While the FBI searched for him, he showed up at an Easter festival at Cornell University, where he had been teaching. With dozens of FBI men looking for him in the crowd, he suddenly appeared on stage. Then the lights went out, he hid inside a giant figure of the Bread and Puppet Theatre which was on stage, was carried out to a truck, and escaped to a nearby farmhouse. He stayed underground for four months, writing poems, issuing statements, giving secret interviews, appearing suddenly in a Philadelphia church to give a sermon and then disappearing again, baffling the FBI, until an informer's interception of a letter disclosed his whereabouts and he was captured and imprisoned.

The one woman among the Catonsville Nine, Mary Moylan, a former nun, also refused to surrender to the FBI. She was never found. Writing from underground, she reflected on her experience and how she came to it:
