A Brief Guide to Maritime Strategy is a deliberately compact introductory work aimed at junior seafarers, those who make decisions affecting the sea services, and those who educate seafarers and decision-makers. It introduces readers to the main theoretical ideas that shape how statesmen and commanders make and execute maritime strategy in times of peace and war. Following in the spirit of Bernard Brodie's Layman's Guide to Naval Strategy, a World War II-era book whose title makes its purpose plain, it will be a companion volume to such works as Geoffrey Till's Seapower and Wayne Hughes's Fleet Tactics and Coastal Combat, the classic treatise that explains how to handle navies in fleet actions. It takes the mystery out of maritime strategy, which should not be an arcane art for practitioners or policy-makers, and will help the next generation think about strategy.
