United States Army Troops were trapped in Pueblo de Los Ángeles, Alta California by José María Flores men.

Tom Lewis joined Flaco, they stopped in Mission Santa Barbara late at night and rented fresh horses and bought food from Lieutenant Talbolt.

Flaco arrived at San Francisco in the evening at 8 PM after a six hundred miles ride with only 3 hours of rest in Monterey, through land filled with unfriendly natives and Mexican Californios.

As part of the surrender Gillespie's Troops marched to the Port of San Pedro and departed Los Angeles on September 30, 1846, on the American merchant ship Vandalia.

Kearny and Stockton's 607 Troops found Flores' 300 men near the San Gabriel River about 6 miles south of Pueblo de Los Ángeles.
