Upon hearing of the Siege of Los Angeles,
on October 4, 1846, Commodore Robert F. Stockton sent U.S. Navy Captain William Mervine and the American
ship Savannah to the port of San Pedro to assist Captain Archibald H. Gillespie in military operations.
Arriving two days later, Mervine set out on October 7th with sailors, marines and
bear flaggers to recapture the town.
The Americans had occupied Los Angeles in
August of that year, and residents had hidden some weapons, some by burying them. On August 14, 1846,
Pablo Vejar (brother of Juan Nepomuceno Ricardo Vejar) communicated a plan to Maria Casilda Soto (of Rancho La Merced) and Maria
Francisca 'Pancha' Perez (wife of ranchero Felipe Lugo), both sympathetic Californio
patriots, to hide one of the small ceremonial Plaza cannons used for
firing salutes on feast days and other celebrations. Vejar, with the help of
Carlos Ballesteros and Jose Domingo Bermudez, transported the old cannon to the
peach orchard of Maria Inocencia Reyes. Reyes then buried
the cannon in the orchard for safekeeping. The Reyes home adjoined that of
Antonio Maria Lugo, located at what today would be the corner of
San Pedro Street & 2nd Street. the orchard may have been separate
from the property, it was likely adjacent to the Reyes home.
Another slightly different account, from the article “Battle of
Dominguez Ranch" by J.M. Guinn, conveys that upon the approach of Stockton and
Fremont’s forces in 1846 that Maria Inocencia Reyes’ mother, Maria Clara Cota
(with the assistance of her her daughters), buried the cannon in a cane field
near their residence on the east side of Alameda Street near First.
On September 27, 1846 when the time had come to put
the gun to use, Maria Inocencia Reyes delivered the gun to Jose
Dolores de Altagracia “Huero” Higuera, who with the help
of a local British carpenter made a cannon carriage from a cart belonging to
Louis Vignes.
Mervine's commenced with little
knowledge of the terrain or enemy forces. His troops were inadequately armed and they possessed no horses, wagons or cannons. General Jose
Flores' force, was similarly equipped with lances, knives and old firearms that had been
hidden, but they did have the recently unearthed cannon. This
brass four-pounder or pedrero (swivel gun)
was described by Jose Francisco de Paula
Palomares as bronze and of about six inches in diameter, that
it was “mounted over some iron-rimmed
carreta wheels, and bound with reatas” and that at length it received the
name "Conico".
Mervine and his troops marched on October 7 and
reached Dominguez Rancho, where they camped for the night, within view of an
advance detachment of Flores' troops. There was some shooting during the
night, but with no effect other than keeping Mervine's party on the alert.
Then, setting off at daybreak, the American force advanced just to the north of
Rancho San Pedro.
The little four-pounder was placed upon the narrow
trail that the Americans needed to follow. Ropes were lashed to the limber to quickly pull
the gun into the brush for reloading. Californio horsemen deployed at a
safe distance from the trail on the enemy flanks. These simple tactics proved
effective. When the Americans came within range (about 400 yards), the cannon was fired and
quickly pulled back into the brush, followed by covering musket fire from the horsemen.
Mervine's forces were at a disadvantage on foot against an
enemy they could neither see nor count. Upon realizing they could not reach Los
Angeles, they had no choice but to retreat. The battle lasted less
than an hour; and five hours later Mervine's forces were back aboard their ship in San
Pedro Bay. Four seriously wounded Americans died and were buried on a
little island in San Pedro Bay called Isla
de los Muertos (Island of the Dead). Mervine's troops reboarded the
Savannah, and after a few days, sailed north to Monterey.
