Battle of Río San Gabriel

The Battle of Río 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.

On January 12, Frémont and two of Pico's officers agreed to terms for a surrender. Articles of Capitulation were signed on January 13 by Frémont, Andrés Pico and six others at a ranch at Cahuenga Pass (modern-day North Hollywood). This became known as the Treaty of Cahuenga, which marked the end of armed resistance in California.
