Battle of Rio San Gabriel

The Battle of Rio San Gabriel, fought on 8 January 1847, was a decisive action of the California campaign of the Mexican–American War and occurred at a ford of the San Gabriel River, at what are today parts of the cities of Whittier, Pico Rivera and Montebello, about ten miles south-east of downtown Los Angeles.
After the Battle of San Pasqual, the battered Army of the West, commanded by General Stephen W. Kearny, went to the headquarters of Commodore Robert F. Stockton at San Diego, California. Stockton's next objective was to recapture Pueblo de Los Angeles. That settlement had been previously captured by Stockton's forces but was left in the command of Captain Archibald Gillespie and had been lost to the Californio militia, commanded by General José María Flores in the Siege of Los Angeles that Fall. Stockton's force, which included six cannons this time, left San Diego on 28–29 December.
