In every war there are men who are not citizens of the country with whose army they are fighting, and the "soldier-of-fortune" is as much a recognised adjunct of modern armies as he was in the days of knight-errantry. In the American revolutionary war both the colonial and British forces were assisted by many foreigners, and in every great and small war since then the contending armies have had foreigners in their service. In the Franco-Prussian war there was a great number of foreigners, among them having been one of the British generals who took a leading part in the Natal campaign. The brief Graeco-Turkish war gave many foreign officers an opportunity of securing experience, while the Spaniards in the Hispano-American war had the assistance of a small number of European officers. Even the Filipinos have had the aid of a corps of foreigners, the leader of whom, however, deserted Aguinaldo and joined the Boer forces. There is a fascination in civilised warfare which attracts men of certain descriptions, and to them a well-fought battle is the highest form of exciting amusement. All the world is interested in warfare among human beings, and there are men who delight in fighting battles in order that their own and public interest may be gratified. It may suggest a morbid or bloodthirsty spirit, this love of warfare, but no spectacle is finer, more magnificent, than a hard-fought game in which human lives are staked against a strip of ground--a position. It is not hard to understand why many men should become fascinated with warfare and travel to the ends of the earth in order to take part in it, but a soldier of fortune needs to make no apologies. The Boer army was augmented by many of these men who delighted in war for fighting's sake, but a larger number joined the forces because they believed the Republics were fighting in a just cause.
