"My comrades and I," he said, indicating his four Brothers, "wish to denounce that man as a German spy!" He spoke quietly, and pointed an accusing finger at Captain Dickerson. "What's that?" cried the major, in great surprise. Jimmy repeated his statement, and as he did so he kept his eyes on the face of the accused. The latter smiled faintly, but did not seem at all alarmed. "Have you any evidence to support this amazing statement?" asked the major. "Plenty," answered Jimmy, and then, briefly, he told what he and his chums had seen. During the dramatic recital, which was corroborated at several points by Roger and Bob, as well as Franz and Iggy, the captain never said a word. He continued calmly smoking a cigarette he had lighted. "Can this be possible?" exclaimed a lieutenant, and he seemed to shrink away from Captain Dickerson. "Have you anything to say regarding the accusation of these lads, Captain Dickerson?" asked the major, at length. The accused flicked away the end of his cigarette. He looked at the boys, smiling cynically, and then answered calmly: "No, I have nothing to say!" "It is my duty--my painful duty--to order you under arrest then," said the major. "And it breaks my heart to do it. You were once my lieutenant and--" Emotion overcame him, but he signaled to a captain, who summoned two orderlies, and in charge of these Captain Dickerson was led away under arrest. "This matter will be taken up later, Sergeant Blaise," said the major. "It will have to wait until after the battle. He might better have been killed in action a dozen times than have this happen," he added rather ambiguously. "This is terrible!" "It was hard to do this, after he had saved our lives," said Jimmy, "but it had to be." "Yes," assented the major brokenly, "it had to be. And now let's forget it in giving battle to the Huns! It's up to us to redeem whatever wrong he may have done," and he nodded in the direction of the captain, who had been led away under arrest. "He took it calmly enough," remarked Bob, as the five Brothers marched away. "Never turned a hair," added Roger. "But you've got to have nerve to be a spy." "I suppose they'll shoot him," observed Franz. "They don't have time for hanging any more. He'll face a firing squad all right." "It's too bad!" declared Jimmy. "But it had to be. I'll say this for him--he's a brave man to venture back here, when he might be sure he'd be exposed--if not by us by some one else. Yes, he's a brave man!" It was with no very light hearts, at first, that Jimmy and his chums marched on toward the front lines where they had been ordered to take their places for the general advance. The scene of the last half-hour preyed on their minds. But they were satisfied that they had done their duty. "What's the program, sir!" asked Jimmy, as he reported to his second lieutenant.
