Book excerpt: "Through colourful and lively historical illustrations as well as strategic theory, Gray shows how sea power, when integrated with land and air power, increases the combatant's opportunities and choices. With dozens of examples from the Greek and Persian wars of the fifth century B.C. through the recent war in the Gulf, Gray systematically demonstrates the ways sea power has been used, and how it might have been used, to win battles and wars. His thought-provoking commentary is certain to become essential reading for the makers of defense policy today. The Leverage of Sea Power is an important and original contribution to the science of warfare historically and in the nuclear age." --
