Robert E. Lee - Mexican-American War

Mexican-American War

Lee distinguished himself in the Mexican–American War (1846–48). He was one of Winfield Scott's chief aides in the march from Veracruz to Mexico City. He was instrumental in several American victories through his personal reconnaissance as a staff officer; he found routes of attack that the Mexicans had not defended because they thought the terrain was impassable.

He was promoted to brevet major after the Battle of Cerro Gordo on April 18, 1847. He also fought at Contreras, Churubusco, and Chapultepec and was wounded at the last. By the end of the war, he had received additional brevet promotions to Lieutenant Colonel and Colonel, but his permanent rank was still Captain of Engineers and he would remain a Captain until his transfer to the cavalry in 1855.

For the first time, Robert E. Lee and Ulysses S. Grant met and worked with each other during the Mexican-American War. Both Lee and Grant participated in Scott's march from the coastal town of Vera Cruz to Mexico City. Grant gained wartime experience as a quartermaster, Lee as an engineer who positioned troops and artillery. Both did their share of actual fighting. At Vera Cruz, Lee earned a commendation for "greatly distinguished" service. Grant was among the leaders at the bloody assault at Molino del Rey, and both soldiers were among the forces that entered Mexico City. Close observations of their commanders constituted a learning process for both Lee and Grant. The Mexican-American War concluded on February 2, 1848.

After the Mexican War, Lee spent three years at Fort Carroll in Baltimore harbor. During this time, his service was interrupted by other duties, among them surveying and updating maps in Florida. Lee declined an offer from Narciso López's Cuban rebels to lead their fight against Spain.
