Presently the "mules" began to get active. "Mules" are the guns of the French mountain artillery. As those guns are drawn by mules, the soldier in the Argonnes calls them "mules" for short. They are very light guns with a flat trajectory, and are fired from a distance of only 50-100 yards behind the French front. The shells of those guns whistled above our heads. Cutting their way through the branches they fly along with lightning rapidity to explode in or above some trench. In consequence of the rapid flight and the short distance the noise of the firing and the explosion almost unite in a single bang. Those "mules" are much feared by the German soldiers, because those guns are active day and night. Thus day by day we lived through the same misery. XIX CHRISTMAS IN THE TRENCHES Winter had arrived and it was icy cold. The trenches, all of which had underground water, had been turned into mere mud holes. The cold at night was intense, and we had to do 48 hours' work with 12 hours' sleep. Every week we had to make an attack the result of which was in no proportion to the immense losses. During the entire four months that I was in the Argonnes we had a gain of terrain some 400 yards deep. The following fact will show the high price that was paid in human life for that little piece of France. All the regiments (some of these were the infantry regiments Nos. 145, 67, 173, and the Hirschberg sharpshooting battalion No. 5) had their own cemetery. When we were relieved in the Argonnes there were more dead in our cemetery than our regiment counted men. The 67th regiment had buried more than 2000 men in its cemetery, all of whom, with the exception of a few sappers, had belonged to regiment No. 67. Not a day passed without the loss of human lives, and on a "storming day" death had an extraordinarily rich harvest. Each day had its victims, sometimes more, sometimes fewer. It must appear quite natural that under such conditions the soldiers were not in the best of moods. The men were all completely stupefied. Just as they formerly went to work regularly to feed the wife and children they now went to the trenches in just the same regular way. That business of slaughtering and working had become an every day affair. When they conversed it was always the army leaders, the Crown Prince and Lieutenant-General von Mudra, the general in command of the 16th Army Corps, that were most criticized.
