Eleven o'clock came at length, when, just after the sentry's cry of "All's well," Frank arose to his feet, and cautiously approaching the window, pushed open the shutter and looked out. The sentry was seated on the ground at the corner of the cabin, holding his musket across his knees, now and then stretching his arms, and yawning. Jack remained seated on the bed, while Frank debated long and earnestly with himself as to what course it was best to pursue. Should they spring out and overpower the sentry where he sat? This could not be accomplished without a fight, for the sentry was a large, powerful-looking man, and, without doubt, possessed of great strength; besides, if a struggle did ensue, the noise would attract the attention of the guard at the other side of the cabin, who would lend prompt assistance, and, with these two men opposed to them, escape would be impossible. Still, there seemed to be no other course for them to pursue, and Frank had already proposed the plan to the mate, and was about to push open the shutter and make the attempt, when he noticed that the sentinel had leaned his head against the cabin, and was sleeping soundly.
"Jack," he whispered, "get out of this window quickly, and make the best of your way into those bushes," pointing to a thicket that stood about twenty feet from the cabin. "As soon as I see you safe, I will follow. Don't make any noise now."
The mate touched his cap, lingered for an instant to press Frank's hand, then mounted lightly into the window, reached the ground without arousing the rebel, and, in a moment more, disappeared in the bushes. Frank was about to follow when the sentry suddenly awakened, rubbed his eyes, gazed vacantly about him, and then sank back to his former position. As soon as Frank felt certain that he was asleep, he again opened the shutter, descended noiselessly to the ground, and, after carefully closing the window, sprang into the bushes.
"Shiver my timbers, sir," whispered Jack, seizing his officer's hand, "that was well done. Won't the Johnnies be surprised when they call all hands in the morning, and find us missin'?"
But the fugitives were by no means safe, neither had their escape been accomplished. They were still inside of the lines, and might, at any moment, stumble upon a picket. But it was necessary that they should get as far away from the camp as possible before their escape became discovered, and Frank, without waiting to receive the congratulations of the mate, who now looked upon their escape as a certain thing, threw himself on his hands and knees, and moved slowly across a field that extended a mile back of the cabin, and which must be crossed before they could reach the woods. Their progress was slow and laborious, and it was two hours before they reached a road which ran in the direction in which they supposed the river to lie. Not having seen any pickets, and now feeling quite certain that they were outside of the lines, they arose to their feet, and commenced running at the top of their speed. The road ran through a thick woods, but they had no difficulty in following it, as the moon was shining brightly. Just before daylight, they arrived at the Mississippi. It was a pleasant sight to their eyes, and both uttered a shout of joy when they found themselves standing on its banks. But their spirits fell again, when, on glancing up and down the river as far as their eyes could reach, they could not see a vessel of any kind in sight. They were not yet at their journey's end. There might be a gun-boat close by, hid behind one of the numerous points that stretched out into the river, or there might not be one within a hundred miles. They must not linger, however, for they were not free from pursuit until they were safe on board some vessel.
Sorrowfully they bent their steps down the river, listening for sounds of pursuit, and eagerly watching for signs of an approaching steamer; but the day wore away, and the fugitives, who began to feel the effects of hunger, halted, and were debating upon the means to be used in procuring food, when, to their joy, they discovered smoke around a bend, and, in half an hour, a transport, loaded with soldiers, appeared in sight. They at once commenced waving their hats, to attract the attention of those on board, who evidently saw them, but being suspicious that it was a plan of the rebels to decoy them into shore, turned off toward the opposite bank.
"I should think they ought to see us," said Frank, and he commenced shouting at the top of his lungs. A moment afterward a puff of smoke arose from the forecastle, and a twelve-pounder shot plowed through the water, and lodged in the bank at their very feet. It was then evident to them that they had been taken for rebels. After watching the boat until it disappeared, they again turned their faces down the river. Night overtaking them without bringing any relief, the fugitives, hungry and foot-sore, lay down in the woods and slept.
