Shamrock and Sword

Book excerpt: Shamrock and Sword's setting is the U.S.-Mexican War, remembered by Americans as an illustration of Manifest Destiny, the inevitable extension of the American frontier. It is remembered differently by Mexicans, who lost a substantial portion of their territory to an invading army. Perceptions on both sides of the border will be reshaped by Robert Ryal Miller's account of American soldiers who deserted to fight in the Mexican army. Miller uncovers the reasons for these desertions, presenting the soldiers' stories as they are revealed in records of the time. Many of these deserters were immigrant Irishmen.
