Just where I was posted, the trench was traversed; that is, from the parapet there ran at right angles, for about six feet, a barricade of sandbags, that formed the upright line of a figure T. The angle made by this traverse gave some protection from the wind that swept through the trench. Here I spread my blanket. The night was bitterly cold, and I shivered for lack of an overcoat. In coming away hurriedly from London, I did not take an overcoat with me. In Egypt, it had never occurred to me that I should need one in Gallipoli; and the chance to get one I had lost. But I was too weary to let even the cold keep me awake. In a few minutes I was as sound asleep as if I had been far from all thought of war or trenches. It seemed to me that I had just got to sleep when I was awakened by a hand shaking my shoulder roughly, and by a voice shouting, "Stand to, laddie." It was Mac. I jumped to my feet, rubbing my eyes. "What's the matter?" I asked. "Nothing's the matter," said Mac. "Every morning at daybreak ye stand to airms for an hour." I looked along the trench. Every man stood on the firing platform with his bayonet fixed. Daybreak and just about sunset are the times attacks are most likely to take place. At those times the greatest precautions are taken. Dawn was just purpling the range of hills directly in front when word came, "Day duties commence." Periscopes were served out, and placed about ten feet apart along the trench. These are plain oblong tubes of tin, three by six inches, about two feet high. They contain an arrangement of double mirrors, one at the top, and one at the bottom. The top mirror slants backward, and reflects objects in front of it. The one at the bottom slants forward, and reflects the image caught by the top mirror. In the daytime, by using a periscope, a sentry can keep his head below the top of the parapet, while he watches the ground in front. Sometimes, however, a bullet strikes one of the mirrors, and the splintered glass blinds the sentry. It is not an uncommon thing to see a man go to the hospital with his face badly lacerated by periscope glass.
