In this timely historical study, Katz details the overt and covert activities by which the governments, intelligence agencies, and business interests of other nations sought to influence the course of events of the Mexican Revolution. In unearthing the startling stories of intrigue and derring-do told here, the author has, for the first time, made full use of German, Austrian, French, Cuban, Mexican, Spanish, and British sources, as well as recently declassified material from the United States.
