The lessons to be learnt from Cromwell's campaigns have been thus epitomized by General Baden-Powell:--"There is one thing that ought not to escape the attention of students, namely the success that attended Cromwell's method of rallying his troops whenever they got dispersed. When things looked bad, as they did on one or two occasions, when some of his cavalry were defeated and the rest scattered, he never lost heart and his men never lost heart; they knew they had to rally again and attack somewhere else. Very often the enemy were deceived by that, thinking that the Roundheads were scattered and broken up, and took no further notice of him until they suddenly found him attacking from quite a new direction. That was the secret of his success on many occasions, and one that has its lesson to-day, just as it had in those days--that when all seems pretty bad and you are scattered and broken, keep up a good heart and get together again and have another go." With scarcely the change of a word these remarks will account for the prolongation of the war for two years after the occupation of the Boer capitals. The Boer leaders, like their great prototype Cromwell, owed much of their success to their novel and skilful use of mounted troops. The European conception of the functions of mounted troops had been stereotyped for some time; Cavalry screens an advancing army, prevents the enemy observing its dispositions, acts as its eyes and ears; and so forth. It is true that Great Britain had already for at least a generation employed Mounted Infantry in colonial wars; but the innovation had never been approved of on the Continent, where it was regarded as a cheap and inefficient British substitute for Cavalry. Yet the famous postscript "unmounted men preferred,"[2] which was affixed to the acceptance of the help proffered by the Australian Colonies, shows that at first the power of mounted troops acting not as the eyes and ears of an army, but as a mobile and supple "mailed fist," was not understood. In ten weeks, however, the tune changed, and it was "preference given to mounted contingents." When the grand operations were over, the enemy's chief towns occupied, and the lines of communication fairly secure, the necessity for mounted troops became still more apparent. The Boers saw that it was useless for them to campaign at large. They took to _guerilla_, and restricted themselves generally to independent horse raids against which foot troops were powerless. Gradually the proportion of horses to men in the British columns rose, until practically all the combatants were mounted, and at last the Cromwellian principle that the best military weapon is a man on a horse was fully accepted.
