Alfred Thayer Mahan, The Influence of Sea Power upon History… (1890)
“ Such was that bloody Battle of the Four Days, or Straits of Calais, the most memorable sea-fight of modern days; not, indeed, by its results, but by the aspect of its different phases; by the fury of the combatants; by the boldness and skill of the leaders; and by the new character which it gave to sea warfare. More than any other this fight marks dearly the passage from former methods to the tactics of the end of the seventeenth century. For the first time we can follow, as though traced upon a plan, the principal movements of the contending fleets. ”
