This review of causes and motives may be supplemented by a brief statement of what is meant by the Triple Alliance and Triple Entente, terms which come into common prominence in discussing European politics. They indicate the division of Europe, so far as its greater Powers are concerned, into two fully or partially allied bodies, the former consisting of Germany, Austria and Italy, the latter of Great Britain, France and Russia. These organizations are of comparatively recent date. The Alliance began in 1879 in a compact between Germany and Austria, a Dual Alliance, which was converted into a Triple one in 1883, Italy then, through the influence of Bismarck, joining the alliance. In this compact Austria and Germany pledged themselves to mutual assistance if attacked by Russia; Italy and Germany to the same if attacked by France. The Triple Entente—or Understanding—arose from a Dual Alliance between France and Russia, formed in 1887, an informal understanding between Britain and France in 1904 and a similar understanding between Britain and Russia in 1907. Its purpose, as formed by Edward VII, was to balance the Triple Alliance and thus convert Europe into two great military camps. When organized there seemed little probability of its being called into activity for many years. Chapter III. STRENGTH AND RESOURCES OF THE WARRING POWERS Old and New Methods in War—Costs of Modern Warfare—Nature of National Resources—British and American Military Systems—Naval Strength—Resources of Austria-Hungary—Resources of Germany—Resources of Russia—Resources of France—Resources of Great Britain—Servia and Belgium Within the whole history of mankind the nations of the earth had never been so thoroughly equipped for the art of warfare as they were in 1914. While the arts of construction have enormously developed, those of destruction have fully kept pace with them; and the horrors of war have enormously increased side by side with the benignities of peace. It is interesting to trace the history of warfare from this point of view. Beginning with the club and hammer of the stone age, advancing through the bow and arrow and the sling-shot of later times, this art, even in the great days of ancient civilization, the eras of Greece and Rome, had advanced little beyond the sword and spear, crude weapons of destruction as regarded in our times. They have in great part been set aside as symbols of military dignity, emblems of the “pomp and circumstance of glorious war.”
