The night was fortunately dark. They went slowly forward and brought the route almost up to within calling distance of the Germans. The Verey lights, shattering the darkness over No Man's Land, did not disclose them to the enemy. Suddenly, a Boche machine gun mechanically turned its attentions toward the place where they were working. With a tightening of every muscle, Talbot heard the slow whisper of the gun. As it turned to sweep the intervening space between the lines, the whisper rose to a shirring hiss. The men dropped to the ground, flattening themselves into the earth. But Talbot stood still. Now, if ever, was the time when an example would count. If they all dropped to the ground every time a machine gun rattled, the job would never be done. So, hands in his pockets, but with awful "wind up," he waited while the soft patter of the bullets came near and the patter quickened into rain. As it reached him, the rain became a fierce torrent, stinging the top of the parapet behind them as the bullets tore by viciously a few inches above his head. Then as it passed, it dropped into a patter once more and finally dropped away in a whisper. Talbot suddenly realized that his throat was aching, but that he was untouched by the storm. The men slowly got to their feet and continued their work in silence. Although the machine gun continued to spatter bullets near them all through the hours they were working, not once again did the men drop when they heard the whisper begin. The job was finally done and they filed wearily back.

The attack was timed to come off at dawn. An hour before, while it was still as black as pitch, the tanks moved again for their final starting-point. McKnutt's machine was the first to go.

"Cheero, McKnutt," we said as he clambered in. "Good luck!"

The men followed, some through the top and some through the side. The doors and portholes were closed, and in a moment the exhaust began to puff merrily. The tank crawled forward and soon disappeared into the blackness.

She had about fifteen hundred yards to go, parallel with the Hindenburg Line, and several trenches to cross before coming up with the enemy. We had planned that the tanks would take about three quarters of an hour to reach their starting-point, and that soon after they arrived there, the show would begin.

Since it was still dark and the attack had not commenced, McKnutt and his first driver opened the windows in front of them. They looked out into impenetrable gloom. It was necessary to turn their headlights on, and with this help, they crawled along a little more securely. A signal from the driver, and they got into top gear. She bumped along, over shell-holes and mine-craters at the exhilarating speed of about four miles an hour, and then arrived at the first trench to be crossed. It was about ten feet wide with high banks on each side.

"One up!" signals the driver. The gears-men get into first gear, and the tank tilts back as it goes up one side of the trench. Suddenly she starts tipping over, and the driver takes out his clutch and puts on his brake hard. McKnutt yells out, "Hold tight!" and the tank slides gently down with her nose in the bottom of the trench. The driver lets in his clutch again, the tank digs her nose into the other side and pulls herself up slowly, while her tail dips down into the bottom of the trench. Then comes the great strain as she pulls herself bodily out of the trench until she balances on the far side.

It was now no longer safe to run with lights. They were snapped off. Once more the darkness closed around them, blacker than ever. They could no longer find their route, and McKnutt jumped out, walking ahead with the tank lumbering along behind. Twice he lost his way and they were obliged to wait until he found it again. Then, to his intense relief, the moon shone out with a feeble light. It was just enough to illumine faintly the ground before them and McKnutt reëntered the tank, and started on.

Their route ran close to the sides of an old quarry and they edged along cautiously. McKnutt, with his eyes glued to the front, decided that they must have already passed the end of the quarry. That would mean that they were not far from the spot where they were to wait for the signal to go into action. The moon had again disappeared behind the clouds, but he did not consider it worth while to get out again. The journey would be over in a few minutes.

Suddenly, his heart took a great dive and he seemed to stop breathing. He felt the tank balance ever so slightly. Staring with aching eyes through the portholes, he saw that they were on the edge of the old quarry, with a forty-foot drop down its steep sides before them. The black depth seemed bottomless. The tank was slipping over. When she shot down they would all be killed from concussion alone.
