"Well, it's nothing more than we knew would happen," remarked Frank, as his frame tingled with the excitement of the coming fight which he knew would soon be upon him.

"That's so," agreed Bart. "But what gets me is that the line was broken so quickly. I thought it would be afternoon at least before the Huns got as far as this."

The lines opened up to let the newcomers through so that they could go to the rear and re-form.

"How about it?" Frank asked of a machine gunner whom he knew, as the man limped by him, supported by a comrade. "We didn't expect to see you fellows so soon."

"It was the mist," was the reply. "The Huns got within thirty yards before we tumbled to it. We did the best we could but they just swamped our position before we could get our cross-fire going. Even at that we mowed them down in heaps with our rifle fire, but they kept on coming. For every dead man there were twenty live ones to take his place. We put up a stiff fight, but there were too many of them. It seemed like millions. They're coming now like a house afire and you boys want to brace."

"We're braced already," muttered Billy through his clenched teeth, as he gripped his rifle until it seemed as though his fingers must leave their imprint on the stock.

There was a short period of waiting, more trying by far than any actual fighting.

Then the storm broke!

In front of them rank after rank of gray-clad troops came in sight, stretching back as far as the eye could see. The mist had wholly vanished now and the boys could see their enemy. It seemed as though the machine gunner had not exaggerated when he said that there were millions. They were like the waves of the sea.

But the stout hearts of the American boys never quailed. Time and again they had met these men or their fellows and driven them back at the point of the bayonet. They had outfought and outgamed them. They had sent them flying before them. They had seen their backs.
