The two worked together to fight that war....................and later in SW Va..........one surrendered to the other in 1865......................the Mexican American war took place in the 1840s..............



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.^[44] The Mexican–American War concluded on February 2, 1848.
