In the XVIIth century the Boers of the Netherlands, made a voluntary settlement in South Africa, and there under the Southern Cross they were joined by French Puritans, who had fought under Condé and who left their country after the revocation of the Edict of Nantes, and also by some persecuted sectaries from Piedmont. The two stocks, although one was of Teutonic and the other of Celtic origin, easily came together, and under the pressure of common interests and common dangers were consolidated and vulcanized: and if in the previous generation the English Pilgrim Fathers of the _Mayflower_ had directed their course to the south instead of to the west, and had cast anchor off the shore of that distant region of Good Hope, it is probable that a mighty nation would have been founded in South Africa. Cromwell as the military leader of the Commonwealth Boers is, at least in England where the military art has not been scientifically studied, one of the suppressed characters of history. His political achievements, as is perhaps natural in a community which courts the voter and despises the soldier, have put out of sight the means by which he mainly won them; namely his genius as a cavalry and partisan commander. An ungainly, narrow-minded, bigoted, bucolic squireen of Huntingdon, lacking in every quality which we are accustomed to associate with a cavalry officer, inaugurated an era in the history of Mounted Troops. His methods are studied on the Continent, and the German Staff has recently discovered that he was the first leader to use cavalry as a screen to hide the movements of the main body. Yet there is no evidence that he ever studied the military art, and he did not become a soldier until he had reached his fourth decade. In the Royalist Army opposed to him were soldiers by profession and experience; officers and men who had been under Gustavus Adolphus in the Thirty Years' War; for in the XVIIth century the services of aliens were in request on the Continent, and at one time no less than eighty-seven senior officers of British nationality were serving in the Swedish Army, then the most renowned in Europe. Yet Cromwell with his "Eastern Association," his Ironsides, his yeomen and raw levies, beat the Royalist Army, officered from the same class which is still believed to possess the monopoly of the aptitude for leading men in war, by exercising the homely qualities of energy, self-control, endurance, and practical common sense applied instantly to the occasion of the moment.
