One way or the other it meant the "Seventy-fives"--the "Admirable Seventy-five"--the seventy-five millimetre field pieces that stopped the Germans' Paris drive at the Marne--the same that gave Little Willie a headache at Verdun,--the inimitable, rapid firing, target hugging, hell raising, shell spitting engine of destruction whose secret of recoil remained a secret after almost twenty years and whose dependability was a French proverb. At Valdahon where American artillery became acquainted with the Seventy-five, the khaki-clad gun crews called her "some cannon." At seven o'clock every morning, the glass windows in my room at the post would rattle with her opening barks, and from that minute on until noon the Seventy-fives, battery upon battery of them, would snap and bark away until their seemingly ceaseless fire becomes a volley of sharp cracks which sent the echoes chasing one another through the dark recesses of the forests that conceal them. The targets, of course, were unseen. Range elevation, deflection, all came to the battery over the signal wires that connected the firing position with some observation point also unseen but located in a position commanding the terrain under fire. A signalman sat cross-legged on the ground back of each battery. He received the firing directions from the transmitter clamped to his ears and conveyed them to the firing executive who stood beside him. They were then megaphoned to the sergeants chief of sections. The corporal gunner, with eye on the sighting instruments at the side of each gun, "laid the piece" for range and deflection. Number one man of the crew opened the block to receive the shell, which was inserted by number two. Number three adjusted the fuse-setter, and cut the fuses. Numbers four and five screwed the fuses in the shells and kept the fuse-setter loaded. The section chiefs, watch in hand, gave the firing command to the gun crews, and number one of each piece jerked the firing lanyard at ten second intervals or whatever interval the command might call for. The four guns would discharge their projectiles. They whined over the damp wooded ridge to distant imaginary lines of trenches, theoretical cross-roads, or designated sections where the enemy was supposed to be massing for attack. Round after round would follow, while telephoned corrections perfected the range, and burst. The course of each shell was closely observed as well as its bursting effect, but no stupendous records were kept of the individual shots. That was "peace time stuff."
