In England it was decided to form mounted infantry charged with the additional duty of augmenting the fire of a cavalry division, and of furnishing the commander-in-chief with a reserve possessing the requisite mobility to permit its being thrown to any threatened point of the long battle lines of today. But of what importance is the fire of a single battalion in the large armies of the present day? The principal drawback to the employment of mounted infantry is, however, that, when mounted, it is defenseless against cavalry, and that, while in motion, it really needs a supporting force. In the Boer war the mounted infantry grew finally to a strength of 50,000 men. As it was not confronted by cavalry, it made good during the execution of wide turning movements, which Lord Roberts employed with success for the purpose of striking the flank of the Boers, who always rapidly extended their lines. In spite of these good services, it could not be denied that mounted infantry had many faults. The men knew nothing of the care of their mounts, as is evidenced by the large percentage of horses which became unserviceable. As mounted infantry units were improvised bodies, they lacked the requisite training in marching and tactical employment. After the war had lasted for some time, the mounted infantrymen, however, had completely forgotten their infantry character and deported themselves like cavalrymen, even if only as poor ones. Thus, we find toward the close of the campaign numerous attacks made by mounted infantry on the British side, as, strange to relate, also on that of the Boers. In this experiment of creating mounted infantry, all those drawbacks which had been learned for centuries were exemplified. As an improvisation, mounted infantry disturbs the cohesion of organizations; if permanently organized, it must become cavalry, just as the dragoons became cavalry: for mounted infantry is neither flesh, fish, nor fowl and cannot endure. The British Drill Regulations (1904) for mounted infantry lay down the following principles for its employment: In the practical employment of mounted infantry, sight must not be lost of the fact that this arm is drilled and trained as infantry. On account of its greater mobility, it should be able to cover greater distances, and, in addition, be capable of executing wider turning movements than infantry. As a rule, mounted infantry is to be used in the following cases:
