Then Dennis sprang down, regardless of the fumes. At the bottom of the steps he was conscious of treading on something soft, but did not stay to examine it, for a ray of light filtering in from a fissure in the roof showed him dark forms scurrying away in the distance along the boarded passage.

The hand-grenade had got a move on the enemy, and, followed by a dozen men of the platoon, he led the way, gripping his rifle, and loosing a couple of rounds from the hip as he ran.

One of the bullets evidently found its mark, for a man lay writhing on the ground where another passage turned off at right angles. The man tried to seize his legs, but instantly let go his hold with a hoarse cry as Tiddler's bayonet settled all disputes, and Dennis darted round the angle.

The passage ended in a strange place; a large dug-out which had been partially unroofed by one of our shells earlier in the morning, and knee deep amid the loose earth which had poured in, half filling it, twenty Germans turned at bay, under the command of a very tall officer.

There were only eight men with Dennis, for the other four were still groping their way somewhere behind in the darkness of the passage, and the young lieutenant realised in a flash of time that he was seriously outnumbered and must act promptly.

A big sergeant jumped at him with a shout, but before the lunging bayonet had crossed his own, Dennis fired and shot the man dead.

"Put your hands up and surrender!" he said sternly in German to the rest; and the first to obey was the tall officer, who came scrambling over the loose earth with both arms outstretched.

"We are your prisoners, sir," he said, holding his revolver as though he were presenting the butt to Dennis. And the men of the British platoon lowered their bayonets with disappointment in their faces.

It meant some of their number escorting the prisoners to the rear, they knew, and that was not the hope they had had in their hearts.

But their disappointment was short-lived, for, as the tall officer came within a stride of the young lieutenant, he suddenly shouted: "Now you have them, men! Down with these infernal English!" And, reversing his own weapon, he fired three shots at Dennis Dashwood in rapid succession.
