Sloat raises the flag over Monterey; Mexico's California falls without a shot
By July 1846, word of war with Mexico had taken almost three months to reach the Pacific coast. Commodore John D. Sloat, already anchored at Monterey aboard the USS Savannah, sent sailors and marines ashore from the Savannah, Cyane, and Levant on July 7. The garrison offered no resistance, and Sloat raised the American flag over the Monterey Custom House, ending both Mexican rule and the short-lived California Republic declared weeks earlier at Sonoma.
Monterey's capture gave the United States a functioning capital on the Pacific before the war with Mexico was even decided, and the town governed California until 1849, hosting its first Constitutional Convention. A flag raised without a shot fired became the paperwork foundation for California statehood four years later.
QWhat job did a Navy chaplain take on in occupied Monterey?
Walter Colton, a Navy chaplain, became Monterey's first American alcalde, a Spanish-derived title for a town magistrate who handled both civil disputes and criminal cases. Colton had no legal training and inherited a Mexican-era legal system he barely understood, yet he stayed in the post as Monterey transitioned from Mexican tariff town to American territorial capital. He later wrote about the experience, giving one of the few firsthand civilian accounts of how the occupation actually functioned day to day, well beyond the flag-raising ceremony itself.
QWhy was Sloat sitting in Monterey harbor for days before he acted?
Sloat's Pacific Squadron had already been reinforced and stationed near California before the war even started, but he refused to attack without solid confirmation that Congress had formally declared hostilities. News traveled by ship around Cape Horn or overland, so official word took nearly three months to reach him after the May 13 declaration. His caution meant American settlers at Sonoma acted on their own weeks earlier, staging the Bear Flag Revolt without any Navy backup at all.
QWhat had Mexican officials been collecting at the Custom House before Sloat arrived?
The building where Sloat raised the flag was not a fort or government palace but a customs house, where Mexican authorities taxed hides, tallow, and other goods moving through Monterey's port, then the main trading hub of Alta California. Its ordinary function as a tax office makes its later fame almost accidental. That same structure is preserved today inside a California state park, still standing on the spot where a single afternoon converted a Mexican tariff post into the seat of an American territorial government.
