The leader of the Army of the Potomac was watching from the other side of the Rappahannock with a terrible eagerness. The man who had not wished the command of the splendid Union army, who had deemed himself unequal to the task, was now proving the correctness of his own intuitions. He had taken up his headquarters in a fine colonial residence on one of the highest points of the bank. He was surrounded there by numerous artillery, and the officers of his staff crowded the porches, many of them already sad of heart, although they would not let their faces show it. But Burnside, now that his men had forced the river in such daring fashion, began to glow with hope. Such magnificent troops as he had, having crossed the deep, tidal Rappahannock in the face of an able and daring foe, were bound to win. He swept every point of the field with his glasses, and from his elevated position he and his officers could see what the troops in the plain below could not see, the long lines of the Confederates waiting in the trenches or in the woods, their cannon posted at frequent intervals. But Burnside hoped. Who would not have hoped with such troops as his? Never did an army, and with full knowledge of it, too, advance more boldly to a superhuman task. He saw the gallant advance of the Pennsylvanians and he saw them drive off Pelham. Hope swelled into confidence. With an anxiety beyond describing he watched the further advance of Meade and his Pennsylvanians. Stonewall Jackson also was watching from his convenient hill, and his small staff, mostly of very young men, clustered close behind him. Jackson no longer used his glasses, as Burnside was doing. Meade and his Pennsylvanians were coming close to him now. The great Union batteries on Stafford Heights must soon cease firing or their shells and shot would be crashing into the blue ranks. "It cannot be much longer," said Harry. "No, not much longer," said Dalton. "We'll unmask mighty soon. How far away would you say they are now, Harry?" "About a thousand yards." "Over a half mile. Then I'll say that when they come within a half mile Old Jack will give the word to the artillery to loosen up." Harry and George, in their intense absorption, had forgotten about the other parts of the line. In their minds, for the present at least, Jackson was fighting the battle alone. Longstreet was forgotten, and even Lee, for a space, remained unremembered. They were staring at the brigades which were coming on so gallantly, when the jaws of death were already opened so wide to receive them. "They're at the half mile," said Dalton, who had a wonderful eye for distance, "and still Old Jack does not give the word."
