Part of the acclaimed "Special Campaign" series of works intended for serious professional students of military history each volume is interspersed with strategical and tactical comments and illustrated by numerous sketches. Marlborough's leadership of the Allied armies from 1701 to 1710 during The War of the Spanish Succession consolidated Britain's emergence as a front-rank power, while his ability to maintain unity demonstrated his diplomatic skills. He is often remembered by military historians as much for his organisational and logistic skills as tactical abilities. However, he was also instrumental in moving from the siege warfare that dominated the Nine Years' War, arguing one battle was worth ten sieges.
