“If only we could capture that battery!” This was the thought in the mind of many a Union commander and private. A desperate attempt was made, a whole regiment advancing upon it in one solid mass. Twice the battery belched forth, tearing great holes in the Union ranks, but these were closed up and soon the boys in blue stood at the very muzzles of the cannons. But now came a ringing shout from the Confederate rear. A troop of cavalry was coming up, and in the fore were the gallant Montgomery Grays, with Andy in the saddle, looking as brave and wildly daring as any of them. Ever since the defeat at Williamsburg they had been spoiling for a fight, and now they rode in and surrounded the battery. “Charge!” came the cry from Captain Montgomery, and the Grays charged as never before, riding fairly on top of the bayonets of the gallant Union men. Down went many a poor foot-soldier on his back, while half a dozen saddles were emptied of owners who would never ride again. The shock was fearful, and it was instantly followed by a hand-to-hand conflict upon every side. For ten minutes this continued, and during that time Captain Montgomery received a severe bayonet thrust through his left arm. He might have been killed had not one of his men seen the act and shot dead the Union soldier who did the deed. Then an additional force of Confederate cavalry dashed up, and the Union regiment was compelled to retreat, leaving two hundred dead and wounded upon the field. “Arlington!” It was a call from Captain Montgomery, who still sat upon his horse, although pale and weak from loss of blood. “Yes, captain,” and Andy touched his plumed hat. “Ride down into yonder woods and ask General Parkhurst, if you can find him, if we can cross the new road at that point. I imagine the enemy is trying to plant a battery up there somewhere.” “I will, sir. But, captain, hadn’t you better go to the rear and have your wound dressed?” “I’ll go later on. Hurry now, for every moment is precious.” Saluting, Andy dashed away upon his mission. The woods mentioned were low and thick, and the Confederates had cut two roads through them to transport supplies from one part of the vast battlefield to another. Never dreaming of danger in that territory, Andy dashed along among the trees until a turn in the path was gained. Suddenly a shout went up. “A Johnny Reb, boys, and on horseback! Capture him!” Instantly Andy halted. But it was too late. From the woods upon either side of the path appeared at least a dozen Union skirmishers, and the young Confederate was instantly surrounded, while several rifle barrels were pointed directly at his head.
