Germany did not turn her eyes seriously toward the navy until the Emperor William II read Mahan's book, "The Influence of Sea Power upon History." Previous to that epochal event, Germany had relied on her army to protect her interests and enforce her rights, being led thereto by the facts of her history and the shortness of her coast-line. But the strategically trained mind of William grasped at once the situation laid bare by Mahan; and his military training led him to quick decision and prompt action. The necessary machinery was soon set in motion, with the amazing result that in twenty years the German navy became the second in power and perhaps the first in efficiency in the world. Was this feat accomplished by prodigal expenditures in building vessels and other material of all kinds, and enlisting and commissioning a large number of officers and men? No, the expense was less than that of building our navy, even if a liberal allowance be made for the relative cheapness of things in Germany; and the mere enlisting and commissioning of officers and men was the simplest part of the undertaking. How was it accomplished? In the simplest way imaginable: by following Moltke's plan of solving hypothetical war problems, and adapting the military war game (_Kriegspiel_) to naval forces; playing numberless war games, and deciding from those games the naval strategy best adapted to Germany's needs--not only in matters of general principle, not only as to tactics, training, education, co-operation with the army, and the size of fleet required to carry out the policy of the nation--but also as to the composition of the fleet, relative proportions of vessels of the various types, and the characteristics of each type. Nothing was left to chance; nothing was decided by guessing; no one man's dictum was accepted. The whole problem was attacked in its entirety, and a general solution found; and after this, the various divisions and subdivisions of the problem were attacked and solved, in obedience to the same principles, in accordance with the results obtained at _Kriegspiel_.
