Where did the Mexico war happen?

Answer 1

It started on the Mexico-Texas border as part of clashes between Texan and Mexican troops on a no-man's-land, but quickly escalated after the US declared war on Mexico on May 13, 1846. Most battles were fought in northern Mexico and its territories, such as California, New Mexico and Nuevo Leon. It wasn't going well for Americans, until General Winfield Scott opened a new war front on eastern Mexico, by landing on the port of Veracruz, on the Gulf of Mexico in March 9, 1847. He advanced into central Mexico by fighting several battles on cities like Tuxpan, Perote, and Puebla; then finally entering Mexico City and defeating its forces in September 15, 1847. There was an important guerrilla fighting on cities such as San Jose del Cabo and chihuahua until February 2, 1848 when the Guadalupe-Hidalgo Treaty was signed, thus ending the war.
