I, too, had been listening for the staccato of the machine gun, which is the most penetrating, mechanical and wicked, to my mind, of all the instruments of the terrible battle orchestra, as sinister as the clicking of a switch which you know will derail a passenger train. The men were halfway to the German trench, now. Two and a half minutes of the allotted five had passed. In my narrow sector of vision not one man had yet fallen. They might have been in a manoeuver and their goal a deserted ditch. Looking right and left my eye ran along the line of sturdy, moving backs which seemed less concerned than the spectator. Not only because you were on their side but as the reward of their steadiness, you wanted them to conquer that stretch of first-line fortifications. Any second you expected to see the first shell-burst of the answering German barrage break in the midst of them. Then came the first sharp, metallic note which there is no mistaking, audible in the midst of shell-screams and gun-crashes, off to the right, chilling your heart, quickening your observation with awful curiosity and drawing your attention away from the men in front as you looked for signs of a machine gun's gathering of a human harvest. Rat-tat-tat-tat in quick succession, then a pause before another series instead of continuous and slower cracks, and you knew that it was not a German but a British machine gun farther away than you had thought. More than ever you rejoiced in every one of the bursts of stored lightning thick as fireflies in the blanket of smoke over the German trench, for every one meant a shower of bullets to keep down enemy machine guns. The French say "_Belle!_" when they see such a barrage, and beautiful is the word for it to those men who were going across the field toward this shell-made nimbus looking too soft in the bright sunlight to have darts of death. All the shell-bursts seemed to be in a breadth of twenty or thirty yards. How could guns firing at a range of from two to five thousand yards attain such accuracy!
