For the civilians herded into the ranks the sounds of shell and bullet were strange and unexpected as well as frightening and called out for description. At close quarters an artillery barrage sounded ‘as though the earth were cracking up like an egg of super-gigantic proportions tapped by a gargantuan spoon’: it created, according to the same witness, ‘A veritable crescendo of sounds, so continuous as to merge and blend into a single annihilating roar, the roar of a train in a tunnel magnified a millionfold: only the rattle of the machine-gun barrage, like clocks gone mad, ticking out the end of time in a final breathless reckoning, rises above it’. At a greater distance it was ‘like someone kicking footballs — a soft bumping, miles away’, or a noise, felt rather than heard ‘like the beating of one’s heart after running’. A German infantry officer recalled, ‘If you put your hands over your ears and then drum your fingers vigorously on the back of your head, then you get some idea of what the drumfire sounded like to us’.
