In the year 1830 a French official unearthed, in the valley of the Somme, strange I implements of flint now recognized as weapons with which the men of the old I Stone Age made war. With these modest tools of death, it seems, Neanderthal men , from what is now Germany, and Cro-Magnon men from what is now France, fought fifty thousand years ago for the mastery of the continent, and, after a day of lusty battle, left perhaps a score of dead on the field. Twenty years ago modern Germans and modern Frenchmen fought again, in that same valley, for that same prize, with magnificent tools of death that killed ten thousand men in a day. One art alone has made indisputable progress in history and that is the art of war.
