The men fled helter-skelter in the wildest panic that had come upon them since the outbreak of the war. In vain their officers shouted and cursed at them. The iron bonds of discipline snapped like threads. Soldiers rushed hither and thither like ants whose hill had been demolished by a ruthless foot.
Many fled back toward their second line, pursued by a withering blast of rifle fire that reaped a terrible harvest of wounds and death. Others rushed back into their trenches, crowding and treading upon one another. But even here they were not safe from the great tanks, which lumbered down into the trenches and up on the other side, leaving devastation in their wake, spitting out flame from the guns they carried, while they themselves in their iron armor went on uninjured.
Not only were they frightful engines of offense, but they served as well for defense of the troops that followed after them.
For the first few minutes the slaughter was awful, and it looked as though the whole German line would be forced to give way without putting up any resistance worthy of the name. Prisoners were rounded up by the hundreds. There was no time then to send them to the rear. So they were gathered together in the open spaces, their suspenders were cut so that their trousers would slip down and entangle their legs if they tried to escape in the confusion, a small guard was put over them, and the tanks and the troops went thundering on toward the second line.
But here the resistance began to stiffen. The first paralysis of surprise was past. The heavy guns of the enemy opened up, and from scores of machine gun nests and pill boxes came a storm of bullets. The German officers had got their troops under some semblance of control, and heavy reinforcements were rushed up from the rear. From now on the Allies had an awakened and powerful foe to reckon with.
But despite the sterner opposition, the tanks were not to be denied. On they went, as resistless as fate. Their sides were reddened now, and the wake they left behind them was fearful to look upon.
Through the second line entanglements they crashed as easily as through the first, although this time they met with losses. Some had overturned and others had been struck by heavy shells and put out of action. But even though disabled, the guns on one side or the other were still able to pour out their messengers of death and take savage toll of the enemy.
Jumbo was leading, and close behind followed the boys of the old Thirty-seventh, with Frank and his chums in the van. They were fighting like young Vikings, their rifles empty but their bayonets and hand grenades doing deadly work. Their arms were tired by their terrific efforts, but their hearts were on fire. They felt as though they were treading on air, and the blood ran through their veins like quicksilver. Bunker Hill and Gettysburg spoke through them. The traditions of a hundred glorious battlefields on which Americans had fought was theirs. Now again Americans were fighting, fighting to avenge the murdered women and babies of the Lusitania, fighting to crush the most barbarous tyranny the modern world has known, fighting the battle of freedom and civilization.
So they fought on like demons, smashing a pill box here, routing out a machine gun nest there, until the second line was carried. Then the conquerors paused for breath.
On the whole German front in that region two lines deep the line had been smashed. That crowded hour of stark fighting had cracked the boasted invincible line of Hindenburg and sent the foe flying in confusion toward their third and most formidable line. Thousands of prisoners and scores of guns were among the spoils of victory.
