As Andy ranged up alongside he crowded Harry on the left. The stallion did not like this and turned to bite Firefly. But Andy was ready for him and struck the runaway on the nose. At once Harry sheered off as desired, and away went both horses at right angles to the course previously pursued. Again the rifles from the Union side rang out and Captain Montgomery was slightly wounded in the arm, and Andy had his plumed hat ventilated much against his desires. “I owe you one for that, Arlington,” said the captain, when both were safe for the time being. “I’ll not forget you.” “I think you had better get a more manageable horse after this, captain,” returned the youth, with a smile. “He’s too willing to go over to the enemy.” “I’ll give him another trial. If he runs away again I’ll shoot him,” replied Captain Montgomery, and having once more gotten his stallion under control, he galloped off to obtain further orders from the general in charge. “We are ordered to the breastworks below here,” said the officer, a few minutes later. “A South Carolina regiment has been holding the defense, but matters are getting too hot for them. Forward, boys, and show them what our Grays can do. Hurrah for the Stars and Bars!” and away went the troop of cavalry, flinging up the sod of the cut up field behind them. In two minutes more they were again in the thick of the fray. “The cavalry is coming!” Andy heard one of the Union soldiers ejaculate. “Never mind, Blackwell. Show ’em what sort of stuff the Goreville Volunteers are made of,” added another. “Now we have this ground, let us hold it. Hurrah for McDowell and General Scott!” “The Goreville Volunteers,” thought Andy, and the hot blood rushed to his face. It was Louis’s company! Supposing he should-- “Andy!” It was a yell from his left. He turned swiftly. Sure enough, there was Louis, battling bravely in the midst of half a dozen of the South Carolina men, one of whom was about to stick his bayonet into the Union boy’s breast. “Don’t kill him! Don’t, please!” were the words which rose to his lips, but in the din of battle no one heard him. Then he saw Louis catch hold of the bayonet and thrust it aside. In another moment the two chums found themselves face to face. “Louis! To think we should meet like this!” came from Andy’s white lips. “You must go back! You will be killed, or captured!” “I am fighting as I was told to fight, Andy,” was the determined reply. “Good-bye, and take care of yourself!” and away sped Louis, knocking headlong a Confederate soldier who sought to detain him. Andy had now all he could do to look out for his own welfare; and thus the former chums parted, not to meet again until the Army of the Potomac marched against Richmond, the Confederate capital.
