Quotations
On June 14, 1846, thirty American horsemen known as the Osos (Bears) arrived in Sonoma, under the encouragement of General John Charles Frmont. Americans had ventured into California in the early 1840s to obtain land, but the Mexican government would not allow them to own property or hold offie. The Osos captured General Vallejo at the Sonoma Barracks without violence and proclaimed the California Republic by raising a flag depicting a bear.
