Mexican War of Independence
The Mexican War of Independence () was an armed conflict, and the culmination of a political and social process which ended the rule of Spain in 1821 in the territory of New Spain. The war had its antecedent in Napoleon's French invasion of Spain in 1808; it extended from the Cry of Dolores by Father Miguel Hidalgo y Costilla on September 16, 1810, to the entrance of the Army of the Three Guarantees led by Agustín de Iturbide to Mexico City on September 27, 1821. September 16 is celebrated as Mexican Independence Day.
Fort Point, San Francisco
Mexico won independence from Spain in 1821, gaining control of the region and the fort, but in 1835 the Mexican army moved to Sonoma leaving the castillo's adobe walls to crumble in the wind and rain. On July 1, 1846, after the Mexican–American War broke out between Mexico and the United States, U.S. forces, including Captain John Charles Fremont, Kit Carson and a band of 10 followers, captured and occupied the empty castillo and spiked (disabled) the cannons.
