"Our people still hold it," he said. "I can see their gray uniforms and I have no doubt the besiegers are still in the forest. Yes, there's their signal!" The heavy report of a cannon shot rolled up the valley and Harry saw a shell burst over the fort. Carrington was still at work, playing upon the nerves of the defenders. "While we have ridden through the forest," said Stuart, "a cavalry charge here is not possible. We must dismount, leaving one man in every ten to hold the horses, signal to Colonel Talbot that help has come, and then attack on foot." A bugler advanced on horseback at Stuart's command, blew a long and thrilling call, and then another man beside him broke out an immense Confederate flag. "They see us in the fort and recognize us," said Stuart. "Hark to the cheer!" The faint sound of many voices in unison came up from the valley, and Harry knew it to be the Invincibles expressing joy that help had come. The fort then opened with its own guns, and Stuart's dismounted horsemen, who were armed with carbines, advanced through the forest, using the trees for shelter, and attacking the Northern force on the flank. They and the Invincibles together were not strong enough to drive off the enemy, but the heavy skirmishing lasted until the middle of the afternoon, when a whole brigade of infantry came up from the main army. Then the Northern troops retreated slowly and defiantly, carrying with them all their wounded and every gun. "I've got to take my hat off to the mill hands and mechanics," said St. Clair. "I think, Harry, that if it hadn't been for your skill and luck in getting through we would soon have been living our lives according to their will." Colonel Talbot congratulated Harry, but his words were few. "Lad," he said, "you have done well." Then he and Stuart consulted. Harry, meanwhile, found Langdon, who had been driven back, as St Clair had suspected. He had also sustained a slight wound in the arm, but he was rejoicing over their final success. "Everything happens for the best," he said. "You might have been driven back, Harry, as I was. You might not have met Stuart. This little wound in my arm might have been a big one in my heart. But none of those things happened. Here I am almost unhurt, and here we are victorious." "Victorious, perhaps, but without spoils," said St. Clair. "We've got this fort, but we know it will take a big force to keep it. I don't like the way these mill hands and mechanics fight. They hang on too long. After we drove them out of the fort they ought to have retreated up the valley and left us in peace. If they act this way when they're raw, what'll they do when they are seasoned?"
