Setley went out, shivering in the cold night air. It was a starless night. The lurid flash of the guns lighted the horizon and threw vague shadows across the crater-pitted ground that a few days previously had been the No Man's Land of the contending forces. It was now three miles to the rear of the advancing British line.

A crowd of officers and men wearing steel helmets and great-coats poured across the ground, all making towards the spot where the Tanks were "parked."

"All right, sir," Setley heard one of the sentries report to the senior major. "They did fall a bit close, sir, but not near enough to do any damage."

"Thank goodness!" ejaculated Ralph, but to satisfy himself he approached the landship under his command. Not even the canvas covering was injured, although two Tanks in the vicinity had had their wrappings torn off by the blast of the exploding bomb.

"The fellow evidently knows where the Tanks are," observed Danvers. "Deucedly funny how these Huns find out things behind our lines, and yet not a single enemy airman has ventured over in daylight for the last week. Eh, what's that?"

A Tommy, hurrying past, had shouted some information to a pal. Halting, he repeated the news to the subaltern, speaking with a grim relish.

"'E dropped two bombs, sir, smack into No. 9 Advance Cage, sir. Never seen such a blessed mess in all me life. I'll allow there are a couple o' hundred prisoners snuffed out. Anyway, they've got something to be thankful for. Their carcases won't be used for pigs' food."

"That knocks your information theory on the head," observed Ralph. "The airman evidently trusted to luck and it played a shabby trick on the prisoners."

"Not at all," said Danvers stoutly. "He was trying for the Tanks. The fact that a cage was within five hundred yards of them didn't trouble him at all. Cannon fodder, you see; once these Huns are prisoners they cease to count in the estimation of the German High Command. That's why it is not advisable to commit reprisals upon prisoners. Such a step wouldn't affect the Huns in the slightest. It's a safe card to bombard their 'open' towns by way of reprisals. That makes them squeal."

"Let's be getting back," suggested Ralph, stifling a yawn.
