History & Significance

Pacific Squadron Operations - California and Baja was a Mexican-American War engagement fought in California, 1846. It was a United States victory.

The Pacific Coast Campaign refers to United States naval operations against targets along Mexico's Pacific Coast during the Mexican-American War. It excludes engagements of the California Campaign in areas of The Californias north of the Baja California Peninsula. The objective of the campaign was to secure the Baja Peninsula of Mexico, and to blockade/capture west-coast ports of Mexico-especially Mazatlan, a major port-of-entry for imported supplies. The resistance of Mexican forces to the north in the Los Angeles area and the lack of ships, soldiers and logistical support prevented an early occupation of the peninsula and the west-coast Mexican seaports. The U.S. Navy attempted blockades of the ports three times before being able to successfully blockade and/or occupy them.

Following an easy initial occupation and the capitulation of La Paz by Governor Col. Francisco Palacios Miranda, loyalist residents met, declared Miranda a traitor, and rose in revolt. Under a new governor, Mauricio Castro Cota, and then under the leadership of Manuel Pineda Munoz (who defended Mulege from American landings), the loyalists attempted to expel the Americans from La Paz and San José del Cabo. Pineda was eventually captured and the Mexican army under Cota was finally defeated at Todos Santos but only after the Treaty of Guadalupe Hidalgo that ended the war returned captured regions south of San Diego to Mexico.

Following the July-August 1846 campaign led by the Commander of the U.S. Navy Pacific Squadron, Commodore Robert F. Stockton proclaimed United States control of northern regions of Las Californias (known separately before 1836 as Alta California), on August 17, 1846. On August 19, Commander Stockton ordered Joseph B. Hull, commander of the USS Warren, to blockade Mazatlan. Samuel F. Dupont, commander of the second class sloop-of-war Cyane, was ordered to blockade San Blas (about 125 miles south of Mazatlan). Stockton intended to seize Acapulco, and use it as a base for a joint Army-Navy expedition into Mexico. On September 2, 1846, the Cyane captured two Mexican vessels in the harbor then a landing party spiked 34 cannons in the port of San Blas. On September 7, the Warren seized the Mexican brig Malek Adhel at Mazatlan.

In an August 17 proclamation, Stockton had claimed United States control of the Baja Peninsula. To make good on this claim, Commander Dupont then sailed north to La Paz (on the Gulf of California), seized nine small pearl-fishing boats and secured a promise of neutrality from Colonel Francisco Palacios Miranda, governor of Baja California. On October 1, the Cyane seized two schooners at Loreto (about 150 miles north of La Paz). On October 7, the Cyane shelled Guaymas on the mainland after Colonel Antonio Campazano refused to surrender it. A boarding party from the Cyane seized the brig Condor in that port but, finding it unusable, burned it.
