Another ironic figure was Andres Pico, the last Mexican governor of California and commander of the Mexican forces in California during the Mexican War. He is remembered at the San Pasqual State Historic Battlefield for commanding the only battle which the Mexicans won against U.S. troops. In the Treaty of Cahuenga, Pico negotiated the honoring of Mexican land titles, an important issue for him and his brother Pio, another former jefe politico of California. Together, they owned 532,000 acres in southern California including the sites of the town of Whittier, the San Fernando Valley and Camp Pendleton.
