The vanguard certainly met with no very formidable resistance as it advanced over the rolling country. The sound of firing was continuous, but it came from small squads here and there, and after firing a few volleys the men in gray invariably withdrew. Yet the Northern advance was slow. Colonel Winchester became intensely impatient again. “Why don't we hurry!” he exclaimed. “Of all things in the world the one that we need most is haste. With Jackson tied up before Harper's Ferry, Lee's defeat is sure, unless he retreats across the Potomac, and that would be equivalent to a defeat. Good Heavens, why don't we push on?” He had not yet heard of the fall of Harper's Ferry, and that Jackson with picked brigades was already on the way to join Lee. Had he known these two vital facts his anger would have burned to a white heat. Surely no day lost was ever lost at a greater cost than the one McClellan lost after the finding of Orders No. 191. “Do you know anything about the Antietam, colonel?” asked Dick. “It's a narrow stream, but deep, and crossed by several stone bridges. It will be hard to force a crossing here, but further up it can be done with ease since we outnumber Lee so much that we can overlap him by far. I have my information from Shepard, and he makes no mistakes. There is a church, too, on the upper part of the peninsula, a little church belonging to an order called the Dunkards.” “Ah,” murmured Dick, “the little church of Shiloh!” “What do you mean by that?” “There was a little church at Shiloh, too. The battle raged all around it more than once. We lost it at first, but in the end we won. It's another good omen. We're bound to achieve a great victory, colonel.” “I hope and believe so. We've the materials with which to do it. But we've got to push and push hard.” The colonel raised his glasses and took a long look in front. Dick also had a pair and he, too, examined the country before them. It was a fine, rolling region and all the forest was gone, except clumps of trees here and there. The whole country would have been heavy with forest had it not been for the tramp of war. It was now nearly noon and the sunlight was brilliant and intense. The glasses carried far. Dick saw a line of trees which he surmised marked the course of the Antietam, and he saw small detachments of cavalry which he knew were watching the advance of the Army of the Potomac. Their purpose convinced him that Lee had not retreated across the Potomac, but that he would fight and surely lose. Dick now believed that so many good omens could not fail. A horseman galloped toward them. It was Shepard again, dustier than ever, his face pale from weariness. “What is it, Mr. Shepard?” asked Colonel Winchester. “I've just reported to General McClellan that our whole command at Harper's Ferry, thirteen thousand strong, surrendered early this morning and that Jackson with picked men has already started to join Lee!”
