These essays explore the link between the naval strength and global power of Great Britain and the United States from 1815 to the present. The British Way of Warfare assumed that the country with control of the sea could ensure safe and rapid communications for its commerce. The American theory of naval strategy, on the other hand, assumed that one had to engage the enemy in order to assure command of the sea. These case studies illustrate once again that naval history must include cultural, economic, political, and social contexts.
