Half a minute passed in absolute silence as far as the vicinity of the dug-out was concerned, although three or four hundred yards away the desultory firing still continued. Three quarters of a minute: there was a shuffling sound from the subterranean retreat and the guttural voice of several Huns engaged in excited debate.

"Fifty seconds!" announced Wilmshurst. "Ten seconds more."

"Do not t'row der pomb; we surrender make!" implored a voice.

"Out you come, then; one at a time," ordered Dudley.

With his revolver ready for instant action should the Huns display any signs of treachery the subaltern awaited the appearance of his captives, while the Haussas stood by to back up their young officer should necessity arise.

The first to appear was the junior lieutenant, looking very scared. Finding that nothing occurred to cause him physical hurt he held his arms high above his head, at the same time saying something to his unseen companions.

Then came Hauptmann von Argerlich, pale-faced under his sun-burnt complexion. He had good cause to feel afraid, for he was by no means uncertain that the British possessed a record of his deeds—deeds that might be worthy of the German arms, but certainly would not be regarded with any degree of favour by nations with any respectable code of honour. Poisoning wells, for example, was quite a favourite and pleasant Hun trick when the perpetrators of the outrage were all able to place a safe distance between them and their foes; it was quite another matter when the officer responsible for the dastardly deeds was a prisoner of war.

Three more Germans followed, and then came a full-faced, double-chinned Prussian, wearing an order on his cotton drill uniform. In his hand he held a sheathed sword, the scabbard of which had already been unfastened from the slings.

"I am Commandant Hendrich von Lindenfelt," he announced as captor and captive exchanged salutes. "I make surrender and claim der treatment due to der brisoners of war."

"That'll be all right," rejoined Wilmshurst. "Please keep your sword until the colonel decides—I mean, until you are taken to Colonel Quarrier of the Nth Waffs. Are all the German officers here?"
