What is it like to be in the I.R.A., to fight them, or to be at their mercy? This book explores the lives, deaths, enemies, and victims of the most powerful guerrillas of twentieth-century Ireland: those of the Cork I.R.A. between 1916 and 1923. Drawing on an unprecedented body of sources, including numerous interviews this is a uniquely intimate study of revolution, guerrilla war, and ethnic conflict.
