"Surely he'd hear all this firing, sir," said the man, reluctantly ceasing to wave.

"I think his engine and the wind drowns any noise down here," said the officer. "And if he hears anything, there's plenty of heavy gunfire all along the front going up to him."

"But wouldn't he see the shells falling amongst us, sir, and the bombs bursting, and so on?" said the man.

"Yes; but he is seeing thousands of shells and bombs along the line from up there," said the officer; "and I suppose he wouldn't know this wasn't just a bit of the ordinary front."

Another man crawled over the broken débris of the trench to where they stood. "Mister Waller has been hit, sir," he said; "an' he said to tell you it looks like they was musterin' for another rush over where he is."

"Badly hit?" said the officer anxiously. "All right, I'll come along."

"He sees us, sir," said the man with the flag, in sudden excitement. "Look, he's fired a light."

"Pity we haven't one to fire," said the officer. "But that might be a signal to anyone rather than to us."

He turned to crawl after the man who had brought the message, and at the same moment a rising rattle of rifle-fire and the quick following detonations of bursting bombs gave notice of a fresh attack being begun. Still worse, he heard the unmistakable tat-tat-tat of renewed machine-gun fire, and a stream of bullets began to pour in on them from a group of shell-holes to their right flank, less than a hundred yards from the broken trench they held. Under cover of this pelting fire, that forced the defenders to keep their heads down and cost them half a dozen quick casualties amongst those who tried to answer it, the German bombers crept closer in from shell-hole to shell-hole, and their grenades came over in faster and thicker showers. The little circle of ground held by the group belched spurts of smoke, hummed to the passage of bullets, crackled and snapped under their impact, quivered every now and then to the crash and burst of shells. They had been fighting since the night before; they were already running short of ammunition, would have been completely short of bombs but for the fact of the ground they had taken having held a concreted dug-out with plentiful stores of German bombs and grenades which they used to help out their own supply. The attack pressed savagely; it began to look as if it would be merely a matter of minutes before the Germans rushed the broken trenches they held, and then, as they knew, they must be overwhelmed by sheer weight of numbers. Waller, the wounded officer, had refused to be moved. "I'll stay here and see it out," he said; "I don't suppose that will be long now;" and the other, the young lieutenant who was the only officer left on his feet by this time, could say no more than a hopeful "Maybe we'll stand 'em off a bit yet," and leave him there to push along the trench to where the fire and bombing were heaviest and where the rush threatened to break in.
