The Mexican Punitive Expedition began in March of 1916, when General John J. Pershing led several thousand U.S. troops across the border into Mexico, following attacks on American citizens and property by the followers of Francisco (Pancho) Villa. Pershing’s orders from the War Department were to pursue and disperse Villa and his band or bands.
