Suddenly, in the darkness, they came upon another clump of trees, and as they stumbled into their shelter another volley rang out. One man groaned and stumbled. A comrade lent a supporting hand and dragged him into the woods. "We'll stop here a moment and pick off a few of 'em," said Hal grimly. The Germans were now advancing across the open space. Lying upon the ground, the nine opened fire. They aimed carefully and not a shot was wasted, and so rapid was their fire that the Germans halted. "They don't know how many of us there are," said Hal, "and they are afraid to take a chance. One more volley, men, and then up and run for it again." A final volley was delivered with telling effect, and the English sprang to their feet and darted through the woods. The Germans gave them a parting shot, but there was no pursuit. "That was pretty close," said Chester. "It was, indeed," replied Hal, "and there is one more of our men gone. Was anyone wounded?" he asked, turning to the others. "Shot in the shoulder, sir," replied a man named Brown. "They got me in the arm," said another. "Anyone else?" questioned Hal. There was no reply, and Hal asked: "Are you two men able to go on without assistance?" "Yes," was the reply. "Good! Then come on." All night long the little party continued on their march, and it was not until the first gray streak of dawn showed them, in the distance, the first British line that the boys felt entirely safe. Their report made, they were returning, later in the day, to their quarters to seek a much needed rest, when a well known voice exclaimed: "Well, boys, how are you?" The lads turned quickly about; then each gave a cry of delight and grabbed the man who had accosted them by the hand. "Captain Derevaux!" they exclaimed in a single voice. "No," replied the gallant Frenchman, with a smile. "Major Derevaux, if you please!" CHAPTER IV. THE GERMAN RETREAT BEGUN. Hal and Chester stood for some minutes grasping their friend by the hand. "Major, eh," ejaculated Hal. "I'm glad to hear that!" "So am I," declared Chester. "I am sure no one deserved promotion more than you." "Thanks," laughed the major. "Tell us," said Hal, "what are you doing here? I thought you were with the Southern army." "I am; but I carried dispatches to General French, and if I mistake not, they are important ones. I believe that plans have been brought to a head and that we shall take the offensive soon." "Good!" cried Chester. "We have been retreating long enough." "But," Hal protested, "we can hardly advance in the face of such odds; we must have reinforcements." "Well," said Major Derevaux, "strong reinforcements already are arriving, and I believe that the advance will be general along our whole line." "That will mean severe fighting," said Chester.
