This climax precipitated a general movement toward social and political reform in San Francisco. It was James P. Casey, a graduate of the New York state-prison at Sing Sing, who stuffed a ballot-box with tickets bearing his own name upon them as candidate for supervisor, and as a result of this stuffing declared himself elected. Casey was hurried off to jail by his friends, lest the outraged populace should lynch him on the spot. A mob gathered at the jail. The mayor of the city harangued the people in favor of law and order. They jeered him and remained there most of the night. One leading spirit might have roused the masses to riot; but the hour was not yet ripe. In 1851 a Vigilance Committee had endeavored to purge the politics of the town and rid it of the criminals who had foisted themselves into office. Some ex-members of this committee became active members of the committee of 1856. Chief among them was William T. Coleman, a name deservedly honored in the annals of San Francisco. James King of William was shot on Tuesday, the 14th of May. He died on the following Monday. That fatal shot was the turning-point in the history of the metropolis of the Pacific. A meeting of the citizens was immediately called; an executive committee was appointed; the work of organization was distributed among the sub-committees. With amazing rapidity three thousand citizens were armed, drilled, and established in temporary armories; ample means were subscribed to cover all expenses. Several companies of militia disbanded rather than run the risk of being called into service against the Vigilantis; they then joined the committee, armed with their own muskets. Arms were obtained from every quarter, and soon there was an ample supply. A building on Sacramento Street, below Battery, was secured and made headquarters of the committee. A kind of fortification built of potato sacks filled with sand was erected in front of it. It was known as Fort Gunny Bags. This secured an open space before the building. The fort was patrolled by sentinels night and day; military rule was strictly observed. All things having been arranged silently, secretly, decently and in order--the members of the committee were under oath as well as under arms--they decided to take matters into their own hands; and in order to do this Casey must be removed from jail--peaceably if possible, forcibly if necessary--and given a lodging and a trial at Fort Gunny Bags.
