The Hounds, and they paraded around as if they were military, and even created a headquarters named Tammany Hall within a tent on Kearny Street. In 1849, these thugs began to call themselves the Regulators as they harassed Mexicans and those of Spanish origin as well as extorted money from local businesses for protection services. Anyone who did not pay was likely to lose a nose, ear, or suffer greater bodily injury. However, after a group of 230 men organized into a militia and confronted the Hounds with possible arrest, they quickly fled from San Francisco.
