The author of _Ironclads in Action_, Mr. Wilson, who has made a very thorough study of the future of naval war, has pointed out with great force the most striking difficulties of war in the future as caused by the enormous concentration of forces in a particular tract of country. The result of that concentration must be great difficulties about supply, prolonged battles of an indecisive kind leading to exposure, absence of sleep, and to conditions which would form the severest strain for professional men of war, while those who will now be subject to them will be the ordinary population, not very specially warriors, except so far as patriotism may in some cases make up as regards courage and endurance for absence of military tradition. The vast number of wounded will be exposed for longer periods than was the case in many of the earlier wars; but when we remember Leipsic, and Dresden, and the retreat from Moscow, it is again easy to see that the change is rather in the direction of generalization of conditions, which were formerly exceptional, than a change to conditions wholly without precedent. I have all through this article written of Germany and France as the modern military countries to be taken as a standard in all comparisons. The French have imitated the Germans very closely since the war of 1870. But, although imitation is generally feeble, it must always be borne in mind that the French people have greater military aptitude than the German, and that unless beaten at the beginning of a war they are always in the highest degree formidable. The perfection of system is to be found in Germany, and the peculiarities of the German system are the combination of enlightened patriotism in all its individuality with iron discipline. The system is so strong that unless well managed it would crush out individual responsibility; but the system itself encourages this individual responsibility all down the gradations of the army to the humblest non-commissioned officer and even to the detached private. The universality of promotion by a certain high standard of merit and the absence of jobbery are more thoroughly obtained in Germany than in any other army, and Lord Wolseley’s criticisms on the 1898 manœuvres of our own army, criticisms renewed in 1900, in which he told us that no one had done well in the field, and that this proved that no one could have done his duty during the past year, would be impossible in Germany, and must have shocked military opinion throughout that country.
