This is the first complete detailed study of the military aspects of the first half of this important conflict (1618-1635). Each chapter deals with a particular battle, but Guthrie also examines wider questions of strategy, leadership, armaments, organization, logistics, and war finances. The main emphasis is on the unique character and aspects of the Thirty Years War, with attention to the evolution of warfare and weapons, the impact of this evolution on actual operations, and the replacement of the previously dominant "tericio" style of warfare by the nascent linear system.
