For some time poor Trenck was in a sad condition. In his struggle with the sentinel he had been wounded, while his right foot had got crushed in the palisades. Besides this, he was watched far more strictly than before, for an officer and two men remained always in his cell, and two sentinels were stationed outside. The reason of these precautions, of course, was to prevent his gaining over his guards singly, either by pity or bribery. His courage sank to its lowest ebb, as he was told on all sides that his imprisonment was for life, whereas long after he discovered the real truth, that the king's intention had been to keep him under arrest for a year only, and if he had had a little more patience, three weeks would have found him free. His repeated attempts to escape naturally angered Frederic, while on the other hand the king knew nothing of the fact which excused Trenck's impatience—namely, the belief carefully instilled in him by all around him that he was doomed to perpetual confinement.
It is impossible to describe in detail all the plans made by Trenck to regain his freedom; first because they were endless, and secondly because several were nipped in the bud. Still, the unfortunate man felt that as long as his money was not taken from him his case was not hopeless, for the officers in command were generally poor and in debt, and were always sent to garrison work as a punishment. After one wild effort to liberate all the prisoners in the fortress, which was naturally discovered and frustrated, Trenck made friends with an officer named Schell, lately arrived at Glatz, who promised not only his aid but his company in the new enterprise. As more money would be needed than Trenck had in his possession, he contrived to apply to his rich relations outside the prison, and by some means—what we are not told—they managed to convey a large sum to him. Suspicion, however, got about that Trenck was on too familiar a footing with the officers, and orders were given that his door should always be kept locked. This occasioned further delay, as false keys had secretly to be made before anything else could be done.
Their flight was unexpectedly hastened by Schell accidentally learning that he was in danger of arrest. One night they crept unobserved through the arsenal and over the inner palisade, but on reaching the rampart they came face to face with two of the officers, and again a leap into the fosse was the only way of escape. Luckily, the wall at this point was not high, and Trenck arrived at the bottom without injury; but Schell was not so happy, and hurt his foot so badly that he called on his friend to kill him, and to make the best of his way alone. Trenck, however, declined to abandon him, and having dragged him over the outer palisade, took him on his back, and made for the frontier. Before they had gone five hundred yards, they heard the boom of the alarm guns from the fortress, while clearer still were the sounds of pursuit. As they knew that they would naturally be sought on the side toward Bohemia, they changed their course and pushed on to the river Neiss, at this season partly covered with ice. Trenck swam over slowly with his friend on his back, and found a boat on the other side. By means of this boat they evaded their enemies, and reached the mountains after some hours, very hungry, and almost frozen to death.
Here a new terror awaited them. Some peasants with whom they took refuge recognized Schell, and for a moment the fugitives gave themselves up for lost. But the peasants took pity on the two wretched objects, fed them and gave them shelter, till they could make up their minds what was best to be done. To their unspeakable dismay, they found that they were, after all, only seven miles from Glatz, and that in the neighboring town of Wunschelburg a hundred soldiers were quartered, with orders to capture all deserters from the fortress. This time, however, fortune favored the luckless Trenck, and though he and Schell were both in uniform, they rode unobserved through the village while the rest of the people were at church, and, skirting Wunschelburg, crossed the Bohemian frontier in the course of the day.
Then follows a period of comparative calm in Trenck's history. He travelled freely about Poland, Austria, Russia, Sweden, Denmark and Holland, and even ventured occasionally across the border into Prussia. Twelve years seem to have passed by in this manner, till, in 1758, his mother died, and Trenck asked leave of the council of war to go up to Dantzic to see his family and to arrange his affairs. Curiously enough, it appears never to have occurred to him that he was a deserter, and as such liable to be arrested at any moment. And this was what actually happened. By order of the king, Trenck was taken first to Berlin, where he was deprived of his money and some valuable rings, and then removed to Magdeburg, of which place Duke Ferdinand of Brunswick was the governor.
Here his quarters were worse than he had ever known them. His cell was only six feet by ten, and the window was high, with bars without as well as within. The wall was seven feet thick, and beyond it was a palisade, which rendered it impossible for the sentinels to approach the window. On the other side the prisoner was shut in by three doors, and his food (which was not only bad, but very scanty) was passed to him through an opening.
One thing only was in his favor. His cell was only entered once a week, so he could pursue any work to further his escape without much danger of being discovered. Notwithstanding the high window, the thick wall, and the palisade—notwithstanding, too, his want of money—he soon managed to open negotiations with the sentinels, and found, to his great joy, that the next cell was empty. If he could only contrive to burrow his way into that, he would be able to watch his opportunity to steal through the open door; once free, he could either swim the Elbe and cross into Saxony, which lay about six miles distant, or else float down the river in a boat till he was out of danger.
Small as the cell was, it contained a sort of cupboard, fixed into the floor by irons, and on these Trenck began to work. After frightful labor, he at last extracted the heavy nails which fastened the staples to the floor, and breaking off the heads (which he put back to avoid detection), he kept the rest to fashion for his own purposes. By this means he made instruments to raise the bricks.
On this side also the wall was seven feet thick, and formed of bricks and stones. Trenck numbered them as he went on with the greatest care, so that the cell might present its usual appearance before the Wednesday visit of his guards. To hide the joins, he scraped off some of the mortar, which he smeared over the place.
As may be supposed, all this took a very long time. He had nothing to work with but the tools he himself had made, which, of course, were very rough. But one day a friendly sentinel gave him a little iron rod and a small knife with a wooden handle. These were treasures indeed! And with their help he worked away for six months at his hole, as in some places the mortar had become so hard that it had to be pounded like a stone.
