David Jablonsky has compiled the best writings of four of the most influential theorists of naval and air power in the past century. Alfred Thayer Mahans Influence of Sea Power Upon History, Julian Corbetts Some Principles of Maritime Strategy, Guilio Douhets Command of the Air, and William Billy Mitchells Winged Defense continue to have relevance for students and practitioners of naval and air strategy. They illustrate the continuity of strategic thought, even through current times of great and widespread change.
