Harry wondered if Dick was among those moving troops, but his second thought told him it was not likely. They had learned from spies that the Winchester regiment was mounted, and in all probability it was part of the cavalry that had gone north with Sheridan. But he thought again how strange it was that the two should have been face to face at the Second Manassas, and then after a wide separation, involving so many great battles and marches, should come here into the Valley of Virginia, face to face once more. Mortimer and his assistants presently began to manipulate the flags again, and Confederate signalmen, on a far peak, replied. Harry and St. Clair watched them with all the curiosity that a mystery inspires. "Can we ask again," said Harry, when they had finished, "what you fellows were saying?" Mortimer laughed. "It was a quick dialogue," he replied, "but it was intended for the Yankees down in the valley, who, we learn, have deciphered some of our signals. I said to Strother on the other peak: 'Six thousand?' He replied: 'No, eight thousand!' I said: 'In center or on their right flank?' He replied: 'On their right flank.' I said: 'Two thousand fresh horses?' He replied: 'Nearer twenty-five hundred.' I said: 'Five hundred fresh beeves from the other side of the Blue Ridge.' He replied: 'Great news, we need 'em!' I wish it was true, but it will set our Yankee friends to thinking." "I see. Your talk was meant to fool the Yankees." "Yes, and we need to fool 'em as much as we can. It's a daring venture that we're entering upon, but it's great luck for us to have Sheridan away. It looks like a good omen to me." "And to me, too. We used to say that Old Jack was an army corps, and he was, two of them for that matter. Then Sheridan is worth at least ten thousand men to the Yankees. Good-by, we'd like to see more of your work with the flags, but down below they need Captain St. Clair, who is a terrible fighter. We can't hope to beat the Yankees with St. Clair away." Mortimer smiled, waved them farewell, and, a few minutes later, was at work once more with the flags. Meanwhile, Harry and St. Clair were descending the mountain, pausing now and then to survey the valley with their glasses, where they could yet mark the movements of the Northern troops. When they reached the cove they found that the board and the chess men were put away, and the two colonels were inspecting the Invincibles to see that the last detail was done, while Early made ready for his desperate venture.
