When the Quicksilver Mining Company took over at New Almaden, workers quickly realized they faced a new, worse order. The American owners took a holistic orientation toward the workers, extending the mine’s control over their lives. Quicksilver instituted a company store, monopolizing commerce in “Spanishtown” and jacking up prices for new, inferior goods. The owners claimed title to everything on company land, including the homes workers built for themselves and even the firewood they were accustomed to harvesting for use and sale. Quicksilver banned independent peddlers, merchants, and water carriers, as well as Mexican-run taverns and restaurants. In their place, a company saloon served expensive rotgut. The new mine owners changed the compensation metric to one they controlled and started paying monthly instead of biweekly like the Brits had. Real wages fell, and workers ended up in perpetual debt, borrowing to pay for essentials such as food and funerals. By 1865, New Almaden’s Mexican laborers had had enough of U.S. capitalism, and at least 600 of them (along with some white coworkers) halted production and issued a set of reform demands. The Quicksilver company petitioned the genocidal state militia, which in turn petitioned the Northern California regiment of the Union Army, which, having finished defeating slavery, came to San Jose to intimidate the state’s largest Mexican-American community back into the mine. What had been a relative haven for the state’s Spanish-speaking population during the war and gold rush years became a trap. As much as anywhere this was the birthplace of the Mexican proletariat, forged in contrast and service to the new white owners of California.
