When a country goes to war the first test of its military efficiency is the mobilization of its army. This is a stage in the history of wars which the public is apt to overlook, because the arrangements are necessarily secret and complex, and are carried out in that first hush which precedes _communiqués_ and great conflicts in the field. It is nevertheless true that every war starts in the Department of the Quartermaster General, and that by the nature of this start the issue of a war may be decided. We started well. From August 5, when mobilization began,--in spite of bank holidays and Territorials _en route_ for summer camps,--the whole scheme of concentration and despatch was carried out almost exactly to schedule, and without a hitch. It is calculated that, during the busiest period, the railway companies, now under Government control and brilliantly directed by an executive committee of general managers, were able to run as many as eighteen hundred special trains in five days, an average of three hundred and sixty trains a day, and all up to time. The concentration of the Home Forces and of the Expeditionary Force proceeded concurrently. On August 9 the first elements of the Force embarked, and nine days later the greater part of it had been landed in France, and was moving by way of Amiens to its unknown fortunes. The smoothness, rapidity, above all the secrecy with which the transportation was carried out, made a great impression at the time, and will always be admired. The question of how it was done excited, characteristically enough, less interest. We are a people accustomed to happy improvisations, and it was generally assumed that this national talent had once more come to our rescue; the truth being that in these matters improvisation can seldom be happy, and that for instant and complete success the only method is long and careful preparation in time of peace. For several years the military, naval, and civilian authorities concerned had been engaged upon such a scheme of preparation, and had, indeed, concluded their labours not many months before war broke out. When the day came all railway and naval transport officers were at their posts, and the Railway Executive Committee, in its offices in Parliament Street, was calmly carrying out a time-table with every detail of which it had long been familiar. Such perfect preparedness is rare in our history, and worthy of note. Amidst the vast unreadiness of the nation for war the despatch of the Expeditionary Force, and the magnificent readiness of the fleet which made it possible, stand out in grand relief, not to be lost sight of or forgotten.
