The role he played in WWI.

John J. "Blackjack" Pershing (1860-1948) was promoted to General of the Armies during World War I, the highest rank ever held in the United States Army. After unsuccessfully pursuing Pancho Villa through northern Mexico during the Punitive Expedition in 1915 and 1916, Pershing was given command of the American Expeditionary Force in Europe during World War I. In his later career, he was instrumental in formulating the plan that would later form the basis for the Interstate Highway System.
