Wilson hesitated. If he went after the supposed enemy, they would probably hear him and he would lose the advantage of the surprise. On the other hand, that they now seemed to be going in the direction of the American lines might indicate that, after all, they were a patrol of his own comrades. But while he weighed the chances, the question was solved for him by the fact that the blur again became distinct. And this time it grew larger very rapidly, indicating that the party had at last reached a definite decision. On they came until only a few paces separated them from the Army boys. Just then a star shell rose from the German lines and sent a flare of light stabbing the darkness and clearly revealing a dozen or more Germans. As they were facing the glare they were momentarily dazzled by it, and the Americans peering beneath their black hoods on a level with the ground could have easily escaped detection had they been so inclined. But that instantaneous flash had decided the corporal. The odds were more than two to one, but such odds as that was only a challenge to Yankee fighting blood. "Fire!" he shouted, and five rifles spoke as one. Three of the enemy went down as though stricken by an axe, and another staggered and his rifle clattered to the ground. But the enemy rallied almost instantly, and at a hoarse command there was a return volley. This proved harmless, however, for the boys knew that it would come and bent beneath the edge of the craters until the iron storm had swept over them. "Now, boys, at them with your bayonets!" shouted Corporal Wilson, as soon as he had drawn the enemy's fire. With a leap the American squad was on the level ground and rushing with leveled bayonets at the foe. The Americans had the advantage of the surprise, and their headlong charge would have won instantly if the forces had been equal. But although two went down at once, the others, after yielding ground somewhat, closed in a death grip with their assailants, and there was a furious combat at close quarters. There was no more shooting. It was a matter now of clubbed rifles and bayonet thrusts. Frank found himself engaged in a bayonet duel with a massive German who towered above him in height and probably outweighed him by twenty pounds. He was well trained too in bayonet work and was a most formidable opponent. But he met his master when he crossed bayonets with Frank. The latter had made himself expert by long training under skilful French instructors, and, besides, was the most finished boxer in the regiment. At thrust and parry, feint and riposte, advance and retreat, he stood first among his comrades. Against the furious bull-like rushes of his opponent, he opposed a quickness and agility that more than counterbalanced his enemy's weight It was a contest of a bull against a panther, and the panther won.
