are not completely demoralized. One soon ceases to be surprised at anything in this species of literature, or one would gasp with amazement at the levity with which Cavalrymen throw ridicule on their own Arm. Suddenly and very tardily we come upon an indication of the alternative to that frontal pursuit which gives such meagre results and yet must be continued day and night. "Thus, when it becomes no longer possible to show a front to the pursuing Cavalry in the open, measures must be taken to block the routes upon which his _parallel_ pursuit is operating," etc. Does not the reader feel his brain going when he reads a sentence like this? What antithesis can there be between Cavalry "pursuing in the open" and Cavalry conducting a "parallel pursuit"? There is no more or less probability of open ground in a parallel than in a frontal pursuit. It is the old story. One half of the writer's brain is back in the days of Frederick the Great; the other half is in working in the medium of the present. That is the key to this chapter, from which a Cavalry leader could not gain one concrete, definite rule for his guidance in real war. On pursuit, as on many other topics, the author was more clear and instructive in his earlier work, "Cavalry in Future Wars" (Chapter IV.), where he was not hampered by having to consider Regulations with any pretence to modernity, and where he accordingly spoke with freedom on the absolute necessity of fire-action in pursuit; though he could not even then wholly grasp the corollary, the absolute necessity of fire-action in retreat. II.--THE BRITISH VIEW. Let us now, as in the case of the fight of the Independent Cavalry, contrast the directions given by our own authorities for the great battle of all Arms ("Cavalry Training," pp. 225-229). One point of difference we may dispose of at once. The divisional Cavalry (who are Mounted Infantry) and the "protective" Cavalry (to which there is no German counterpart) behave rationally. They remain with, or drop back to, their respective main bodies, and there make themselves generally useful. The rules for the Independent or Army Cavalry, on the other hand, present a curious study. On the German model, this main mass is, generally speaking, to be posted forward of one of the flanks. (There is no suggestion of a "reserve behind the front.") But we notice at once, with some surprise, that nothing is said about the corresponding hostile Cavalry mass, which, according to von Bernhardi, should be the primary objective, and whose "absolute and complete overthrow" is, according to Sir John French (p. xiv), a "primary necessity."
