To get within the Federal lines was a still more perplexing problem. One device after another proved ineffectual, and the girl was almost in despair. She appealed at last to the general in command of the cavalry in that region,--one of those to whom Stuart had written in her behalf,--and he promptly responded: "At precisely what point have you friends in coöperation with you?" She named a little town within the Federal line where lived some of her nearest friends. "I can manage that," he said. "The point is an insignificant one ten miles within their lines. There are pretty certainly no troops there, and the picket-lines in front are not very strong, as nothing could be more improbable than the raid I shall make in that direction. You can ride, of course." "Of course." "Very well. I'll take a strong force, make a dash through the picket-lines, gallop into the town, and make a foray through the region round about. You will follow my column as closely as you can without placing yourself under fire, and when we reach the town, settle yourself with your friends there, turning your horse loose lest he attract attention. You'd better do that just before we reach the town, and walk the rest of the way. Can you wear a walking-skirt under your riding-habit, and slip off the outer--you see I'm a bachelor, Miss Ronald, and don't understand such things." "You may safely leave all that to my superior feminine sagacity. When shall we start?" "Whenever you wish. Only we'd better march in the afternoon and reach the town after nightfall. The nights are very dark now, and you will perhaps be able to escape observation in the town. Let me see," looking at his watch, "it's now half past one. We could do the thing this afternoon, if you were ready." "I can be ready in fifteen minutes," she replied. "You're very prompt," the officer said, with a suggestion of admiration in his voice. "O, I'm half-soldier, you know. General Stuart approves me." "Very well, then. We'll march in half an hour." The operation was a very simple one, in its military part, at least. The expedition was composed of a force much too strong for resistance by the handful of men available for immediate use on the enemy's part. In the guise of a foraging party it easily dispersed the picket-lines and pushed forward rapidly, taking the little town in its course, but making no halt there. It scoured the country round about, and as soon as Federal forces began to gather for its destruction, it retreated by quite a different route from that by which it had advanced. It was nine o'clock in the evening when Agatha slipped off her horse in the little Maryland town and left it in charge of a trooper. A five-minutes' walk brought her to the house of her friends, where she was safe.
