continued and 30,000 Anglos with 3,000 slaves were settled in Texas by 1835. In 1836, the Texas Revolution erupted. Following losses at the Alamo and Goliad, the Texians won the decisive Battle of San Jacinto to secure independence. At San Jacinto, Sam Houston, commander-in-chief of the Texian Army and future President of the Republic of Texas famously shouted "Remember the Alamo! Remember Goliad". The U.S. Congress declined to annex Texas, stalemated by contentious arguments over slavery and regional power. Thus, the Republic of Texas remained an independent power for nearly a decade before it was annexed as the 28th state in 1845. The government of Mexico, however, viewed Texas as a runaway province and asserted its ownership. The Mexican–American War Mexico refused to recognize the independence of Texas in 1836, but the U.S. and European powers did so. Mexico threatened war if Texas joined the U.S., which it did in 1845. American negotiators were turned away by a Mexican government in turmoil. When the Mexican army killed 16 American soldiers in disputed territory war was at hand. Whigs, such as Congressman Abraham Lincoln denounced the war, but it was quite popular outside New England. The Mexican strategy was defensive; the American strategy was a three-pronged offensive, using large numbers of volunteer soldiers. Overland forces seized New Mexico with little resistance and headed to California, which quickly fell to the American land and naval forces. From the main American base at New Orleans, General Zachary Taylor led forces into northern Mexico, winning a series of battles that ensued. The U.S. Navy transported General Winfield Scott to Veracruz. He then marched his 12,000-man force west to Mexico City, winning the final battle at Chapultepec. Talk of acquiring all of Mexico fell away when the army discovered the Mexican political and cultural values were so alien to America's. As the Cincinnati Herald asked, what would the U.S. do with eight million Mexicans "with their idol worship, heathen superstition, and degraded mongrel races?" The Treaty of Guadalupe Hidalgo of 1848 ceded the territories of California and New Mexico to the United States for $18.5 million (which included the assumption of claims against Mexico by settlers). The Gadsden Purchase in 1853 added southern Arizona, which was needed for a railroad route to California. In all Mexico ceded half a million square miles (1.3 million km2) and included the states-to-be of California, Utah, Arizona, Nevada, New
