is the first work of research and analysis to explore in detail the Irish work inside Britain to establish arms centers and to conduct arms operations and trafficking. It also examines the full extent of the overseas or foreign arms trade and the arms operations of the War of Independence, including the continuance into the truce and treaty eras and up to the outbreak of the Civil War (1922–1923)—all of which reveals how the rebel leaders ran complex, maturing, and capable smuggling and manufacturing enterprises worldwide under the noses of the police, customs, intelligence, and the military for years without getting caught. Quite apart from the battlefield these groups and their activities led to political consequences, playing no small part in producing what were real concessions from Lloyd George’s government. In the last chapter Kautt offers observations and conclusions about overall successes and failures that establishes as a landmark study of insurgent or revolutionary arms acquisition in both Irish and military history.
