Pancho Villa and Black Jack Pershing : the Punitive Expedition in Mexico by James W Hurst

"In 1916-17, the US Army dispatched an expedition under the command of "Black Jack" Pershing over the Mexican border in pursuit of the forces of Francisco "Pancho" Villa, in what has often been described as a bumbling fiasco. Hurst (emeritus, Joliet Junior College) presents a far different picture, however, arguing that Pershing's forces were experienced in counter-guerilla warfare and that they succeeded in their goal of breaking up and neutralizing the forces that Villa was using to launch raids into Texas." - bBNET
