1. The Mexican-American War 1846 - 1848

2. Manifest Destiny The belief that the U.S. was meant to spread west from Ocean to Ocean to spread Democracy and Justice to North America. With the Annexation of Texas in 1845, the U.S. spread over 2/3rds of the land. Annexing Texas greatly upset Mexico who still thought the territory belonged to them.

3. The Offer In 1846 the United States offered Mexico 30 million dollars for their Northern territory. Not only did Mexico say ‘No’ but they were highly offended by the offer.

6. President Polk Declares War! “... American Blood has been shed on American Soil!” Polk used the altercation as a reason to declare war on Mexico on May 13, 1846. Not all of Congress agreed with the aggressiveness of the U.S. military. Two men who voted no for the war were Representatives -one a young man from Illinois named Abraham Lincoln. The other a former President-John Quincy Adams.

15. Zachary Taylor vs. Santa Anna The Battle of Buena Vista – Feb. 22 1847: The Mexicans had close to 16,000 troops compared to 4,500 for the U.S. However, Taylor and a young commander named Jefferson Davis won a stunning victory killing over 500 Mexicans and wounding another 1000.

22. Scott marches to Mexico City April 1847 - On the way to Mexico City, Santa Anna with 9,000 – 10,000 troops was encamped along the main road. Robert E. Lee found a way to attack the Mexicans from the back. Santa Anna never saw the Americans go around him. The battle turned into a bloody route with 1,000 Mexicans killed, another 3,000 captured, and over 5,000 weapons lost.

23. Santa Anna and his fake leg Santa Anna had lost his leg in a previous war and had been fitted for an artificial leg. The Battle of Cerro Gordo turned into a rout so quickly that he lost his fake leg. The artificial leg was later found by a group of soldiers from Illinois. To this day, 150+ years later, the leg is on display in an Illinois War Museum

24. Scott continues his march To continue towards Mexico City, Scott would have to take Chapultepec Castle. The Castle sits 200 feet high...and would be a major task to defeat.

About 13,000 U.S. troops died, but only 1,700 in combat. 11,300 died from the deadly yellow fever disease. Of all the new states only California is a free state.

33. What happened to......Stephen Kearny: The hero who freed California is made governor of Veracruz and later Mexico City. Unfortunately, while in Mexico he catches Malaria and dies in 1848. Many cities, schools, and streets in Kansas, New Mexico, Arizona, and California are named for him.

34. What happened to......Winfield Scott: “Old Fuss and Feathers” served over 50 years in the military a span of 14 U.S. Presidents. He served during the War of 1812, the Indian Wars, the Mexican-American War, and the U.S. Civil War. Ran for President in 1852 but lost because he was against slavery.
