Leaders of the DCPA sought help from black activist groups, and SNCC and SCLC sent state and national representatives. On the evening of June 10, 1963, a prayer vigil for those arrested earlier in the day met with violence as police and deputized garbage men attacked the vigil with clubs and fire hoses, injuring forty-seven. In the aftermath, concerned black property owners stepped forward to post their houses and businesses for those arrested and jailed. Trials began on June 17 under Judge Aiken. The U.S. Justice Department issued a brief that strongly criticized his courtroom procedures, but appeals by local and state NAACP attorneys, working with national lawyers such as William Kunstler, never brought swift federal court relief. On June 21, the special grand jury indicted ten more protest leaders, including SNCC and SCLC representatives, under the John Brown statute.

The legal maneuvers of white authorities began to take a toll. On July 10, the city council enacted an ordinance that further restricted protests. One day later, Martin Luther King Jr. came to Danville and spoke to a large gathering, but refused to lead a march. The SCLC leader returned briefly on July 19, but an SCLC mass jail-in on July 28 proved disappointing. Of the 311 people who agreed to participate, only 77 went to jail. By August, more than three hundred individuals were awaiting trial. Bail bonds had soared to an estimated $300,000 total. Venues for some cases had been moved to locations eighty to two hundred miles away—a hardship on defendants that led to limited federal court intervention. By summer’s end, however, arrests, high bail, restrictive injunctions, and ordinances had worn down and frustrated the Danville movement. No progress had been made on the protesters’ goals—participation in municipal government and services and the hiring of blacks in downtown white businesses.

In late September, SCLC held its annual convention in Richmond, and leaders debated where next to focus the organization’s forces. In at least one instance, King expressed a preference for a massive campaign in Danville or in Birmingham, where the Sixteenth Street Baptist Church bombing had killed four young girls. That autumn SCLC sent representatives to Danville, and negotiations led to the hiring of the city’s first black policeman. An SCLC-led voter registration drive began, but efforts stopped after the assassination of U.S. president John F. Kennedy on November 22. In a city council election the following year, a white segregationist ticket won handily. Meanwhile, civil rights case appeals continued, with some remaining unsettled until 1973 when a circuit court judge suspended the sentences of six demonstration leaders.
