San Francisco's Civic Auditorium was packed the night of June 19-ten thousand in its seats and more in every foot of standing room. (No vessel had sailed through the Golden Gate that day for the first time in forty-five years.) One estimate guessed strikers made up 40 percent of the audience, families, friends, and the general public the balance. A noisy mix of boos and cheers greeted the appearance of Mayor Rossi, escorted by Police Captain W. T. Healy, and interrupting Bridges's review of the strike. Captain E. B. O'Grady, of the Masters and Mates, banged his gavel hard, asking "a respectful hearing and a courteous welcome." He was only partially successful. The mayor was frequently, and similarly, interrupted as he declared he would work for peace without bloodshed and violence. His promise to help the American Federation of Labor (AFL) brought renewed jeers. His advice was "keep cool. Win without violence." His departure won another round of cheers and jeers. Following the mayor, a series of speakers-including Harry Jackson of the Marine Workers Industrial Union-rehearsed their unions' grievances and their strike goals. Several urged a general strike as the only action that could win the strikers' demands.
