As a prominent figure in the occasional capital of a distant province of an occasionally unstable nation, Larkin stood in a position of influence that could easily have been his undoing if he chose the wrong side. The fact that he was able to survive through shifting administrations is testimony to his political skills. Despite being a supporter of Governor
Juan Bautista Alvarado, he did not involve himself with Alvarado's accusations against
Isaac Graham and other foreign residents of the Monterey area, and was not one of those sent to prison in chains in 1840. Larkin loaned money to
Alvarado's successor,
Micheltorena, which he lost when the Governor was overthrown by
Alvarado in 1844. He never applied for Mexican citizenship, which required conversion to Catholicism; instead he renewed his visa annually to maintain his legal status. As a non-citizen, he could not legally own land, but he managed to obtain land grants in the names of his children. In 1842, Monterey was surprised by the actions of U.S. Commodore
Thomas ap Catesby Jones, who landed Marines to take over Monterey in the mistaken belief that war had broken out between the United States and
Mexico. Larkin and
William Hartnell worked to smooth over the situation. Jones was induced to submit a written apology to the angry Mexican officials and withdraw his troops. The Commodore was subsequently removed from his command, but U.S.–Mexican relations remained tense. The successful conclusion to the affair brought Larkin to the attention of officials in
Washington, and in 1843
President Tyler appointed Larkin as the first (and last) American consul to
Alta California. The following year, he thwarted a British attempt to acquire California while he was assisting the
Mexican government in building a smallpox hospital in Monterey. With the rise of
James K. Polk to the Presidency in 1845, war with Mexico seemed unavoidable. Larkin hired
William Leidesdorff as Vice Consul in San Francisco, thus relieving himself of some of the burden of the office.
Bear Flag Revolt Early in 1846, Larkin received instructions from Secretary of State
James Buchanan to begin working covertly to assure all concerned that the United States would support any attempt at secession from
Mexico. Toward this end, he secretly employed
Abel Stearns to work in southern California. He volunteered to go to Mexico City on behalf of the United States to work out a peaceful settlement, but Congress had already declared war by the time his letter arrived in Washington. Larkin had entered into a dialog with General
Mariano Vallejo with the goal of arranging a peaceful annexation of California when the
Bear Flag Revolt began on 14 June 1846 and the General was captured and imprisoned by a band of Americans who had heard a rumor that the Mexican authorities were thinking of arresting all Americans. In 1846, Marine Lieutenant
Archibald Gillespie was sent by President
James Polk with secret messages to U.S. Consul Larkin in
Monterey, California, Commodore
John D. Sloat commanding the
Pacific Squadron and
John C. Frémont. Gillespie, after traveling in secret across Mexico and catching a ship to California, arrived early in June 1846 with the verbal messages from Polk. What was in the messages are unknown but the Bear Flag revolt came as a surprise to Larkin. On July 7, 1846, Commodore John D. Sloat entered Monterey Bay with three ships. His marines and "blue-jackets" (enlisted sailors) raised the American flag over the Customs House. Commodore (Rear Admiral)
Robert Field Stockton replaced
Sloat a week later as commander of the Pacific Squadron. Stockton appointed Fremont commander of the volunteer militia formed around his 60-man
Corps of Topographical Engineers and the Bear Flag Republicans as the
California Battalion. He dispatched 160 of the forces on the
USS Cyane to occupy San Diego and Los Angeles. Larkin joined the force sailing for southern California which by August 13, had peacefully occupied San Diego, California and
Los Angeles. General
José Castro and Governor
Pío Pico fled south. Commodore Stockton, the senior military officer in California, appointed Larkin as Naval agent, and Larkin returned to Monterey. The apparently peaceful conquest of California soon began to fray at the edges in southern California. Revolts broke out in Los Angeles, and the occupation forces under
Archibald Gillespie and his 30-40 men were driven out. José Castro returned, and Larkin moved his family to Yerba Buena (San Francisco) as the
Californios throughout the province were attempting to repel the thinly spread out California Battalion garrison troops and Navy forces. Larkin was captured outside of the city when, against advice, he tried to go to his deathly ill daughter, still in Monterey. Larkin was forced to ride to
Santa Barbara. En route, he witnessed the inconclusive
Battle of Natividad (near
Salinas) from General Castro's side. He was later imprisoned in Los Angeles and was not reunited with his family until after the signing of the
Treaty of Cahuenga which ended four months of skirmishes. His daughter Sophia Adeline died while he was a captive.
California statehood Now free to own land in his own name, Larkin turned his attention to his new opportunities. In partnership with
Robert Semple, he established the city at the Carquinez Straits that became
Benicia, but Larkin's business interests were in San Francisco and he sold out his share after a few years. As he took control of his own affairs, his relationship with Leidesdorff fell apart. By the time
gold was discovered, Larkin had permanently settled in the San Francisco and was in the next few years able to reap a fortune from the economic boom that followed. It was as a representative from San Francisco that he served at the 1849
Constitutional Convention, held in Monterey. ,
Colma, California Early in 1850, he built the first brick building in San Francisco at 1116 Stockton Street. ==Move to New York==
