Expedition in 1838, the first American squadron to circumnavigate the globe. He rejoined Lamb in 1840 for a brief time, before returning to the expedition. By 1841, Revere was promoted to lieutenant. In an unknown year, Revere reportedly saved the British HMS Ganges from shipwreck, for which Revere was "presented with a sword of honor by the governor-general of India." On October 4 1842, Rosanna Duncan Lamb (April 16, 1818 - July 26, 1910) married Joseph Warren Revere in Boston. They had 5 children, although the first 3 died during childhood: John Revere (1844-1849), Frances Jane Revere (1849-1859), and Thomas Duncan Revere (1853-1856). The youngest two were lawyer Paul Revere (1856-1901) and banker Augustus Lefebvre Revere (1861-1910), who both lived through adulthood. In 1846, Revere was deeply involved in the American Conquest of California, part of the Mexican-American War. In June 1846, the Californios declared their independence from America, creating the California Republic and raising Bear Flags across California. On the morning of July 9, 1846, Revere and 70 naval troops arrived at Yerba Buena, lowered the Bear Flag, and raised the American flag in its place - thereby claiming San Francisco as American territory. Later that day, Revere and troops repeated the flag replacement at Sonoma Plaza in Sonoma, California. Revere's actions assisted American forces in bringing the California Republic to an end after 25 days of independence. In 1846, Revere patented Rancho San Geronimo, 8,701 acres of land seized during the Mexican-American war. Revere created a plantation at Rancho San Geronimo, selling timber and farming potatoes. He enslaved Coast Miwok people, native to the Marin County area, to operate the plantation. However, two months later, the Army transferred Revere to San Diego, and Revere "is said to have left the property in the care of a Native-American [presumably Coast Miwok] foreman." Circa 1847, Revere continued to invade Mexican territory in the Mexican–American War. He was commended for his bravery in battle. A Tour of Duty in California In 1849, Roseanna Revere gave birth to Frances Jane Revere. The same year, Revere published his first autobiographical book, titled A Tour of Duty in California: Including a Description of the Gold Region: and an Account of the Voyage Around Cape Horn; with Notices of Lower California, the Gulf and Pacific Coasts, and the Principal Events Attending the Conquest of the Californias.
