The Great Elector began in 1640 a course of laborious and scientific preparation which committed all Prussia, as well as the army, to acquiring what now we call "efficiency." As this plan developed, especially under the Elector's grandson King Frederick William, the next King found himself, as Alexander had done, the chief of an army more highly prepared for war than any other. By means of that army he made himself Frederick the Great, and raised Prussia from a minor position to the first rank of European Powers. Pursuing Frederick William's system of progressive preparation, Prussia continued her prosperous course till William I defeated Austria, then France, and founded the German Empire. This does not mean that the only result of developing national efficiency to its highest point is to secure success in war—in fact, we know that it is not. But it does mean that the same quality—efficiency—which tends to prosperity in peace tends also to victory in war.
Preparing for war was a simple thing in the olden days compared with preparing now, for the reason that the implements of war are much more numerous and complicated than they used to be, especially in navies. A navy is not ready unless all preparations and plans have been made, tested, and kept up to date, to insure that all of the vessels of every kind and all the shore stations will be in material condition, fully equipped and manned by a sufficient and efficient personnel of officers and crews, in time to meet the enemy on advantageous terms, and unless the central authority has already decided what it will do, when any probable emergency shall arise. This was the condition of the German army in 1870. This was also the condition of the British navy, when war broke out in August, 1914; the British navy was ready; and therefore it was able to assume command of the sea at once, drive its enemy's commerce from the ocean, and imprison its fleets in sheltered ports.
In all countries the peace establishment of the army and navy is smaller than the war establishment, for reasons of economy, upon the assumption that there will be enough time after war is declared to get on a war basis before the enemy can strike. But since 1870, all the military nations have realized that the vital struggle of a war takes place before a shot is fired; that the factors that decide which nation shall be the victor and which the vanquished are determined before the war begins; that they are simply "functions" of preparedness. Germany was ready not only for war but for victory, because her troops were so much better trained, organized, and equipped than those of France, and her war plans so much more complete, that she was able to lay France prostrate, before the enormous resources of that country in men and material could rally in her defense.
The relative conditions in which two opposing forces will enter a war, and their relative performances afterward, will depend upon the relative excellence of the war plans made for them, and the thoroughness with which the plans are tested before war breaks. So it is not difficult to see why all the great armies have patterned after Germany, and organized special bodies of officers for the preparation and execution of War plans; and why it is that they endeavor to secure for that peculiar duty the most thorough and industrious of their officers. Owing to the nature of war itself, the principles of warfare apply in their essentials to navies as well as to armies; and so the navies have patterned after the armies and made plans whereby they can get ready to fight in fleet organization on the ocean with the greatest possible effectiveness in the shortest possible time.
During peace times every navy is maintained on a "peace basis"; only such ships and other material being kept in full commission, and only such a number of officers and enlisted men being actively employed, as the appropriations allotted by the government permit. Those ships and other material that are not actually in commission are maintained in reserve, a condition of partial readiness, of which several degrees are recognized, in which a reduced number of officers and men are kept on board, and the various structures and apparatus are kept in as high a degree of readiness as circumstances will permit. In order to man in time of war these vessels in reserve, and insure a sufficient personnel in the active fleet, a "naval reserve" is organized in each country, composed of officers and men who have had experience in the regular navy. They are compelled to undergo a specific amount of training each year, to keep themselves in readiness at all times to answer the call for active service on short notice, and to maintain such communication with the government as will make it easy to locate any man at any moment.
The act of getting ready, the passing from a state of peace to a state of readiness for fighting, is called "mobilization." Mobilization plans are an important element in war plans, but the details of any mobilization plan are of such a confidential nature that it would not be proper to discuss them in public print. There can be no impropriety, however, in making the general statement that in all navies the endeavor is made to keep the mobilization plans continually up to date, and to have them prepared in such detail that every officer and enlisted man in active service, the retired list, the naval reserve, and the naval militia, will become instantly available for a predetermined duty, and that every shore station and every necessary vessel will be ready to take part. The plans prescribe methods in very great detail whereby the ships and other vessels in reserve can be quickly put into commission with full crews of officers and men, all their various equipments, fuel, and ammunition put on board, and the vessels themselves sent out to sea to join the fleet. In addition, plans are made whereby certain auxiliaries can be fitted out at once and put into commission—such as supply ships, ammunition ships, transports, colliers, mine ships, hospital ships, etc. The mass of detailed plans, orders, and instructions is stupendous and bewildering. Years of study, trial, and rectification are required to get them into such condition that the plans can be put into immediate and effective use when war breaks out. The work must be done, however, and with the utmost thoroughness, before war breaks out; otherwise it will never be done, if an active enemy is about, because he will strike at once—and then it will be too late.
In most of the great naval countries the work of mobilizing the fleet is comparatively easy, for the reason that the coast-line is short and is not far from any part of the interior, enabling reserves to live in fairly close touch with the coast and with naval affairs, and so near the coast that they can get quickly to any port. But the conditions in the United States are more difficult than those in any other country, because of the enormous stretch of our coast, the great average distance from any place in our country to the coast, the difficulty of getting a naval reserve that could be of practical use (owing to the ease with which young men can make a comfortable living on land), and the perilous slowness of the nation as a whole to realize the necessity for preparedness.
As an offset to this, we have the 3,000 miles of ocean between us and Europe, and the 5,000 miles between us and Asia; and on account of this we may to a certain extent discount the danger of attack and the preparedness required to meet it. But our discount should be reasonable and reasoned out, and certainly not excessive. Fortunately the problem of how much time we should allow for mobilizing and joining the fleet is easy, as a moment's thought will show us that it must be simply the two weeks needed for a fleet to come from Europe to America; for we must realize that the report of the sailing of the hostile fleet would be the first news we should get of any hostile preparation or intent.
The general situation in which every isolated naval nation stands regarding other nations is not complicated, but very plain. Each nation has, as possible opponents in its policy, certain countries. The naval forces of those countries and the time in which they can be made ready are known with sufficient accuracy for practical purposes. If any isolated naval nation wishes to carry out a policy which any of those countries will forcibly oppose she must either build a navy equal to that of the other country, or else be prepared to abandon any attempt to force her policies. Stating the question in another way, she can carry out only such policies as do not require for their enforcement a navy stronger than she has.
It is true that diplomacy and the jealousies of foreign powers unite to make possible the averting of war during long periods of time. Diplomacy averted war with Germany for forty-three years, but it could not continue to avert war eternally. War finally broke out with a violence unparalleled in history, and possessing a magnitude proportional to the duration of the preceding peace. "Long coming long last, short notice soon past" is a sailor's maxim about storms; and it seems not inapplicable to wars. Certain it is that the frequent wars of savage tribes are far less terrible than the infrequent wars of enlightened powers.
