"Even when you talk of his mass fighting being so good, perhaps you're giving him too much credit," said Billy grudgingly. "He goes into battle with his officer's revolver trained on him, and he knows that if he flinches he'll be shot. He's got a chance if he goes ahead and no chance at all if he doesn't. And you remember at the battle of the Somme how the gun crews were chained to their cannon so that they couldn't run away. You'll notice that we don't use chains or revolvers for that purpose in the American army."

"I heard Captain Baker tell the colonel the other day that what he needed was a brake instead of a spur in handling his bunch of doughboys," chuckled Tom.

"Quit your chinning," commanded Frank suddenly. "Here they come! Now will you boobs tell me that my eyesight's no good?"

"You win," agreed Bart, as a sharp word of command came down the line. "They're coming for fair!"

From the thick woods beyond, a huge force of enemy troops were coming, marching shoulder to shoulder as stiffly and precisely as though they were on parade or were passing in review before the Kaiser himself.

Their artillery, which had been keeping up a steady fire, now redoubled in volume, and a protecting barrage was laid down, in the shelter of which they steadily advanced.

But now the American guns opened up with a roar that shook the ground. The guns were served with the precision that has made American gunnery the envy of the world, and great gaps were torn in the dense masses of the enemy troops. But the lanes filled up instantly, and with hardly a moment of faltering the advance continued.

As the troops drew nearer, it could be seen that all the men were clad in brand-new uniforms as though for a festive occasion.

"Getting ready to celebrate in advance," murmured Bart. "They must feel pretty sure of themselves."

"Just Prussian bluff," growled Tom. "They think it will brace up Fritz, and that we'll think it's all over but the shouting and lighting out for home."
