went for Anson Jones. Armed conflicts The Comanche Indians, whose territory included northwest Texas, furnished the main tribal opposition to the Republic, manifested in multiple raids on Mexican, indigenous, and European settlements. In the late 1830s, Sam Houston negotiated peace between Texas and the Comanches. When Lamar ascended to presidency in 1838 he reversed the Houston administration's policy towards the Native Americans. War soon resumed with the Comanches and Lamar ordered an invasion of Comancheria itself. In retaliation, the Comanches attacked Texas in a series of raids. After peace talks in 1840 ended with the massacre of 34 Comanche leaders in San Antonio, the Comanches launched a major attack deep into Texas, known as the Great Raid of 1840. Under command of Potsanaquahip (Buffalo Hump), 500 to 700 Comanche cavalry warriors swept down the Guadalupe River valley, killing and plundering all the way to the shore of the Gulf of Mexico, where they sacked the towns of Victoria and Linnville. The Comanches retreated after being pursued by 186 rangers and were caught at the Battle of Plum Creek, in which they lost the plunder they had taken. Houston became president again in 1841 and, with both Texians and Comanches exhausted by war, a new peace was established. Although Texas achieved self-government, Mexico refused to recognize its independence. On March 5, 1842, a Mexican force of over 500 men, led by Ráfael Vásquez, invaded Texas for the first time since the revolution. They soon headed back to the Rio Grande after briefly occupying San Antonio. About 1,400 Mexican troops, led by the French mercenary general Adrián Woll, launched a second attack and captured San Antonio on September 11, 1842. A Texas militia retaliated at the Battle of Salado Creek while simultaneously, a mile and a half away, Mexican soldiers massacred a militia of fifty-three Texas volunteers who had surrendered after a skirmish. That night, upon their defeat, the Mexican Army retreated from San Antonio and back to Mexico, while being pursued by Texas soldiers. The Texas Army took the city of Laredo, at which point they were given official orders from Sam Houston to return to San Antonio. Several soldiers ignored this order, and launched a failed battle to retake Ciudad Mier. The Naval Battle of Campeche took place on April 30, 1843, and May 16, 1843. The battle featured the most advanced warships of its day, including the Mexican steamer
