Myres was using sea-power in a specifically British sense for the times. The Americans had their own idea of sea power, expressed in Alfred Thayer Mahan’s great strategic work, ‘’The Influence of Sea Power upon History’’. which advocated maintaining a powerful navy and using it for strategic purposes, such as “command of the sea,” a kind of domination. The United States Naval Academy used this meaning for its motto, ‘’ex scientia tridens’’, “sea-power through knowledge.” It named one of its buildings, Mahan Hall.
