15, 1846, after the city's occupation by the U.S. Navy's Pacific Squadron on July 7, 1846. Late in 1775, Colonel Juan Bautista de Anza led an overland expedition over the Gila River trail he had discovered in 1774 to bring colonists from Sonora New Spain (Mexico) to California to settle two missions, one presidio, and one pueblo (town). Anza led 240 friars, soldiers and colonists with their families. They started out with 695 horses and mules and 385 Texas Longhorn bulls and cows—starting the cattle and horse industry in California. About 600 horses and mules and 300 cattle survived the trip. In 1776 about 200 leather-jacketed soldiers, Friars, and colonists with their families moved to what was called Yerba Buena (now San Francisco) to start building a mission and a presidio there. The leather jackets the soldiers wore consisted of several layers of hardened leather and were strong enough body armor to usually stop an Indian arrow. In California the cattle and horses had few enemies and plentiful grass in all but drought years and essentially grew and multiplied as feral animals—doubling roughly every two years. They partially displaced the Tule Elk and pronghorn antelope who had lived there in large herds previously. Anza selected the sites of the Presidio of San Francisco and Mission San Francisco de Asís in what is now San Francisco; on his way back to Monterey, he sited Mission Santa Clara de Asís and the pueblo San Jose in the Santa Clara Valley but did not initially leave settlers to settle them. Mission San Francisco de Asís (or Mission Dolores), the sixth Spanish mission, was founded on June 29, 1776, by Lieutenant José Joaquin Moraga and Father Francisco Palóu (a companion of Junípero Serra). On November 29, 1777, El Pueblo de San José de Guadalupe (The Town of Saint Joseph of Guadalupe now called simply San Jose) was founded by José Joaquín Moraga on the first pueblo-town not associated with a mission or a military post (presidio) in Alta California. The original San Jose settlers were part of the original group of 200 settlers and soldiers that had originally settled in Yerba Buena (San Francisco). Mission Santa Clara, founded in 1777, was the eighth mission founded and closest mission to San Jose. Mission Santa Clara was from the original San Jose pueblo site in neighboring Santa Clara. Mission San José was not founded until 1797,
