Though in general the infantry bullets cannot do much damage while one is in the trench it happens daily that men are killed by ricochet bullets. The thousands of bullets that cut through the air every minute all pass above our heads. But some strike a tree or branch and glance off. If in that case they hit a man in the trench they cause terrible injuries, because they do not strike with their heads but lengthwise. Whenever we heard of dum-dum bullets we thought of those ricochet bullets, though we did not doubt that there were dum-dum bullets in existence. I doubt, however, if dum-dum bullets are manufactured in factories, for the following reasons:--first, because a dum-dum bullet can easily damage the barrel of a rifle and make it useless; secondly, because the average soldier would refuse to carry such ammunition, for if a man is captured and such bullets are found on him, the enemy in whose power he is would punish him by the laws of war as pitilessly as such an inhuman practice deserves to be punished. Generally, of course, a soldier only executes his orders. However, there exist dum-dum bullets, as I mentioned before. They are manufactured by the soldiers themselves. If the point is filed or cut off a German infantry bullet, so that the nickel case is cut through and the lead core is laid bare, the bullet explodes when striking or penetrating an object. Should a man be hit in the upper arm by such a projectile the latter, by its explosive force, can mangle the arm to such an extent that it only hangs by a piece of skin. Christmas came along, and we still found ourselves at the same place without any hope of a change. We received all kinds of gifts from our relations at home and other people. We were at last able to change our underwear which we had worn for months. Christmas in the trenches! It was bitterly cold. We had procured a pine tree, for there were no fir trees to be had. We had decorated the tree with candles and cookies, and had imitated the snow with wadding. Christmas trees were burning everywhere in the trenches, and at midnight all the trees were lifted on to the parapet with their burning candles, and along the whole line German soldiers began to sing Christmas songs in chorus. "O, thou blissful, O, thou joyous, mercy bringing Christmas time!" Hundreds of men were singing the song in that fearful wood. Not a shot was fired; the French had ceased firing along the whole line. That night I was with a company that was only five paces away from the enemy. The Christmas candles were burning brightly, and were renewed again and again. For the first time we heard no shots. From everywhere, throughout the forest, one could hear powerful carols come floating over--"Peace on earth--"
