That is the human mechanical side of things. More horrible to the unfortunate soldiers of the German army is the devilish punishment inflicted upon them during the past ten days, culminating on that day of battle when every weapon for the slaughter of men, from the heaviest of high explosives to boiling oil and gas-shells, was let loose upon them in one wild tempest of destruction, which blew them out of the earth and off the earth, and frizzled them and blinded them, and choked them and mutilated them, and made them mad. One German boy, who looked not more than fifteen years of age--a child--was found yesterday lying in a shell-hole by the side of a dead man who had been shot through the temple, and he was a gibbering idiot through fear. Not the only one. German officers say that many of their men went raving mad under the strain of our bombardment, and tried to kill their comrades or themselves, or fell into an ague of terror, clawing their mouths, with all the symptoms of the worst shell-shock. Many of our prisoners believe they were betrayed, and were sacrificed coldly and deliberately by their higher command. Before the battle an order of the day was issued to them, telling them to hold out if surrounded and fight their way back with the bayonet, because behind them would be fresh divisions ready to support immediate counter-attacks. Those fresh divisions never appeared. We know that they had no chance of getting near our lines because of our far-reaching fire, and the work of our aircraft--and the men of Messines and Wytschaete and all the ground south of St.-Eloi were cut off and captured, if they did not die. After our first assaults, the enemy, panic-stricken, were more concerned in getting away their guns than in protecting their troops, and they were left to our mercy.
