A minor Californio revolt broke out in Los Angeles and the United States force there of 40–50 men evacuated the city for a time. Later, U.S.forces fought minor scrimmages in the Battle of San Pasqual, the Battle of Dominguez Rancho, and the Battle of Rio San Gabriel. After the Los Angeles revolt started the California Battalion was expanded to a force of about 400 men. In early January 1847 a 600-man joint force of U.S. Marine, U.S. Navy bluejacket sailors, General Stephen W. Kearny's 80 U.S. Army dragoons (cavalrymen) and about two companies of Fremont's California Battalion re-occupied Los Angeles after some minor skirmishes—after four months the same U.S. fag again flew over Los Angeles. The minor armed resistance in California ceased when the Californios signed the Treaty of Cahuenga on 13 January 1847. The Californios who had wrested control of California from Mexico in 1845 now had a new government.
