The reader will ask for the key to this curious discrimination between the "spirits" of Cavalry and Infantry. It is this: The lance and sword, _when pitted against the rifle_, can, if they are used at all, only be used in offence. Men sitting on horseback, using steel weapons with a range of a couple of yards, plainly cannot defend themselves against riflemen. Even the Cavalry tacitly admit this principle, and if they accepted its logical consequence, a logical consequence completely confirmed by the facts of modern war, they would admit, too, that the sword and lance cannot be used for offence against riflemen in modern war. But they will not admit that. "Tant pis pour les faits," they say. "All modern war is abnormal. Our steel weapons dominate combat. Without them we are nothing." In these circumstances they are forced to set up this strange theory--that Cavalry is a peculiarly "offensive" Arm, a theory which the reader will find expressed in all Cavalry writings. On the face of it the theory is meaningless. It is a mere verbal juggle, because, as I said before, there are two parties to every combat, and defence is the necessary and invariable counterpart of offence. All combatant soldiers, including Cavalry, carry firearms, and if Cavalry choose to use these firearms in offence, by hypothesis they will impose fire-action on the defence, whether the defence consists of Cavalry or any other class of troops. Conversely, if they use their rifles in defence, as by hypothesis they must, they will impose fire-action on the attacking force, be it Cavalry or any other Arm. In other words, the rifle governs combat. That is why the lance and sword disappeared in South Africa. Both in offence and defence the Boer riflemen forced the Cavalry to accept combat on terms of fire. And what kind of Cavalry do our Cavalrymen count upon meeting in our next war? They count, incredible as it seems, upon meeting Cavalry not superior, but inferior, to the Boer mounted riflemen, inferior because, as I shall show from von Bernhardi, they defy science, shut their eyes to the great principle of the supremacy of fire, are prepared deliberately to abdicate their fire-power, and hope to engage, by mutual agreement, as it were, and on the understanding that suitable areas of level ground can be found, in contests of crude bodily weight.
