From all these various points of view the Italian campaign of 1859 marked a further important stage in the early development of that new factor which the employment of railways for the purposes of warfare represented; though far greater results in the same direction were to be brought about, shortly afterwards, by the American Civil War of 1861-65. Not only does the real development of rail-power as a new arm in war date therefrom, but the War of Secession was to establish in a pre-eminent degree (1) the possibility, through the use of railways, of carrying on operations at a considerable distance from the base of supplies; (2) the need of a special organisation to deal alike with restoration of railway lines destroyed by the enemy and with the interruption, in turn, of the enemy's own communications; and (3) the difficulties that may arise as between the military element and the technical (railway) element in regard to the control and operation of railways during war. To each of these subjects it is proposed to devote a separate chapter.

[1] In 1847 one of the leading military writers in Germany published a pamphlet in which he sought to prove that the best-organised railway could not carry 10,000 Infantry a distance equal to sixty English miles in twenty-four hours. As for the conveyance of Cavalry and Artillery by train, he declared that this would be a sheer impossibility.
