Poison gas shells added to the horror of the desperate struggle. Aerial torpedoes, missiles from trench mortars, and the deadly shells from the Stokes' guns, rained upon the enemy position. It was a wonder that the Huns stood it as they did; yet, with their back to the wall and unable to retreat or even to take shelter in their deep dug-outs, they fought with a courage that could only be described as fanatical. Ploughing her way through the mazes of barbed wire Setley's Tank came astride a deep trench that flanked one side of the redoubt to where the glacis terminated in what was a few hours before an elaborately constructed covered way bristling with loopholes, each one of which showed the muzzle of a machine-gun. Now there was little left but a crumbling mound of earth and disrupted sand-bags, in which half-buried Germans still maintained a furious but erratic rifle-fire. Almost before he was aware of it Ralph found himself within the once considered impregnable redoubt. There was practically nothing to mark its position. It was only when he found himself confronted by a landship strongly resembling his own that he realized that he had gained his objective, for the oncoming Tank was not, as he at first imagined, one of German workmanship, but a British machine that had entered the redoubt on the opposite side. Narrower and narrower grew the encircling ring of khaki. With bomb and bayonet the British infantry swept the flattened earthwork, until the surviving Huns, finding further resistance useless, threw down their arms and raised shouts of "Kamerad." Greatly to their surprise they found that, contrary to the statements of their officers, the British Tommy is a generous victor. As if by magic the heat of combat gave place to a light-hearted, almost considerate, treatment of the remnant of the garrison of the redoubt, and it was by no means an uncommon sight to see a British soldier bind up the wounds he had inflicted on a German only a few minutes previously. The paucity of prisoners testified to the stubbornness of the enemy resistance. Quickly the captives were formed up and marched to the advance cages--a task not without great peril, since the German gunners, according to their customary indifference to their ill-fated comrades, were putting up a barrage behind the captured position.
