Types of Naval Officers, Drawn from the History of the British Navy

Classic work of history. According to Wikipedia: “Alfred Thayer Mahan (September 27, 1840 — December 1, 1914) was a United States Navy officer, geostrategist, and educator. His ideas on the importance of sea power influenced navies around the world, and helped prompt naval buildups before World War I. Several ships were named USS Mahan, including the lead vessel of a class of destroyers. His research into naval History led to his most important work, The Influence of Seapower Upon History,1660–1783, published in 1890.”
