In early March of 1915 news broke in El Paso that Leonard Worcester Jr., a leading mining executive in the border region, was being held in a Chihuahua jail without trial or release on bond. Officials loyal to Francisco "Pancho" Villa had accused Worcester of defrauding a Mexican company related to a shipment of zinc, a charge without merit. While struggling to convince Mexican officials of his innocence, Worcester found himself in the middle of a maelstrom of economic interests, foreign diplomacy, and revolution that engulfed the U.S.-Mexico border region after 1910. Worcester's 1939 memoir of his "aimless" life describes an important period in U.S. and Mexican history from the perspective of an American miner, musician, and entrepreneur--running counter to the bombast of boosters promoting Manifest Destiny. Introduced, edited, and annotated by Andrew Offenburger, Worcester's first-person account details the expansion of the American West, mining and labor in Colorado, the formation of reservations in Indian Territory, the Great Depression, and the everyday nature of the Mexican Revolution in Chihuahua. Worcester's memoir, one of the few written by an American living in the Mexican borderlands during this important historical era, provides a snapshot of the capitalist development of the American West and borderlands regions in the second half of the nineteenth century and the early twentieth century.
