All the horrors of all the ages were brought together, and not only armies but whole populations were thrust into the midst of them. The mighty educated States involved conceived-not without reason-that their very existence was at stake. Neither peoples nor rulers drew the line at any deed which they thought could help them win. Germany, having let Hell loose, kept well in the van of terror; but she was followed step by step by the desperate and ultimately avenging nations she had assailed. Every outrage against humanity or international law was repaid by reprisals-often of a greater scale and of longer duration. No truce or parley mitigated the strife of the armies. The wounded died between the lines: the dead mouldered into the soil. Merchant ships and neutral ships and hospital ships were sunk on the seas and all on board left to their fate, or killed as they swam. Every effort was made to starve whole nations into submission without regard to age or sex. Cities and monuments were smashed by artillery. Bombs from the air were cast down indiscriminately. Poison gas in many forms stifled or seared the soldiers. Liquid fire was projected upon their bodies. Men fell from the air in flames, or were smothered often slowly in the dark recesses of the sea. The fighting strength of armies was limited only by the manhood of their countries. Europe and large parts of Asia and Africa became one vast battlefield on which after years of struggle not armies but nations broke and ran. When all was over, Torture and Cannibalism were the only expedients that the civilized, scientific, Christian States had been able to deny themselves: and they were of doubtful utility.
