"Hardly as near as that, Major," replied the aide-de-camp. "A quarter of a mile would make no difference with my plan." "Ah, then you have a plan?" replied the captain with a smile. "I am not an engineer, as I believe you are; but I have been looking over those earthworks. I see a place where I believe I could ride my squadron over them; and I presume there is not a large force there, for it has the river on one side. We have something less than six hundred men, all mounted, and I fancy we could ride over the artillerymen it contains." "I don't believe you could get into the works, in the first place," returned the captain with a laugh. "If you did get in, you would find yourself outnumbered two to one." "I should be willing to feel of them, at any rate," added the major. "Do you suppose a general with ability enough to command an army of five or six thousand men would be so stupid as to march from his intrenchments, and, going away ten miles to attack another army, would leave his base of retreat insufficiently manned?" "I supposed they would have been sending up re-enforcements to the battle-field all day; and they could not have done that without reducing greatly the number in the works. However, I am not a very experienced soldier, Captain Woodbine, and I am willing to admit that I should not have undertaken the enterprise on my own responsibility," replied the major. "Of course it may be possible that the garrison within the fort has been reduced to a number equal, or even less, than your force; but I should say it would be foolhardy in the extreme to make such a venture without a certain knowledge of the extent of the force behind the breastworks. But the riflemen have opened on the regiment nearest to them," added the captain, as the crack of a rifle was heard on the other hill, not more than a quarter of a mile distant. Other shots followed in rapid succession; but they were fired one at a time, in accordance with Captain Ripley's tactics. CHAPTER XX THE FLOWING TIDE OF THE ENEMY'S RETREAT Both of the officers on the hill brought their field-glasses to their eyes, and directed them to the regiment in the meadow, which was having more difficulty in advancing than before; for near the higher ground the cattle had cut up the sod much more than farther off. The men scattered about more in their efforts to avoid the soft places. "Those men fire with remarkable precision," said Captain Woodbine. "A soldier drops at every shot they fire, and they discharge their rifles at the rate of at least ten shots a minute." "They can't stand that long," added the major.
