During this time he enlisted the compassion of some of the other sentinels, who not only described to him the lay of the country which he would have to traverse if he ever succeeded in getting out of prison, but interested in his behalf a Jewess named Esther Heymann, whose own father had been for two years a prisoner in Magdeburg. In this manner Trenck became the possessor of a file, a knife, and some writing paper, as the friendly Jewess had agreed to convey letters to some influential people, both at Vienna and Berlin, and also to his sister. But this step led to the ruin, not only of Trenck, but of several persons concerned, for they were betrayed by an imperial secretary of embassy called Weingarten, who was tempted by a bill for 20,000 florins. Many of those guilty of abetting Trenck in this fresh effort to escape were put to death, while his sister was ordered to build a new prison for him in the Fort de l'Etoile, and he himself was destined to pass nine more years in chains.
In spite of his fetters, Trenck was able in some miraculous way to get on with his hole, but his long labor was rendered useless by the circumstance that his new prison was finished sooner than he expected, and he was removed into it hastily, being only able to conceal his knife. He was now chained even more heavily than before, his two feet being attached to a heavy ring fixed in the wall, another ring being fastened round his body. From this ring was suspended a chain with a thick iron bar, two feet long at the bottom, and to this his hands were fastened. An iron collar was afterward added to his instruments of torture.
Besides torments of body, nothing was wanting which could work on his mind. His prison was built between the trenches of the principal rampart, and was of course very dark. It was likewise very damp, and, to crown all, the name of "Trenck" had been printed in red bricks on the wall, above a tomb whose place was indicated by a death's-head.
Here again, he tells us, he excited the pity of his guards, who gave him a bed and coverlet, and as much bread as he chose to eat; and, wonderful as it may seem, his health did not suffer from all these horrors. As soon as he got a little accustomed to his cramped position, he began to use the knife he had left, and to cut through his chains. He next burst the iron band, and after a long time severed his leg fetters, but in such a way that he could put them on again and no one be any the wiser. Nothing is more common in the history of prisoners than this exploit, and nothing is more astonishing, yet we meet with the fact again and again in their memoirs and biographies. Trenck at any rate appears to have accomplished the feat without much difficulty, though he found it very hard, to get his hand back into his handcuffs. After he had disposed of his bonds, he began to saw at the doors leading to the gallery. These were four in number, and all of wood, but when he arrived at the fourth, his knife broke in two, and the courage that had upheld him for so many years gave away. He opened his veins and lay down to die, when in his despair he heard the voice of Gefhardt, the friendly sentinel from the other prison. Hearing of Trenck's sad plight, he scaled the palisade, and, we are told expressly, bound up his wounds, though we are not told how he managed to enter the cell. Be that as it may, the next day, when the guards came to open the door, they found Trenck ready to meet them, armed with a brick in one hand, and a knife, doubtless obtained from Gefhardt, in the other. The first man that approached him, he stretched wounded at his feet, and thinking it dangerous to irritate further a desperate man, they made a compromise with him. The governor took off his chains for a time, and gave him strong soup and fresh linen. Then, after a while, new doors were put to his cell, the inner door being lined with plates of iron, and he himself was fastened with stronger chains than those he had burst through.
For all this the watch must have been very lax, as Gefhardt soon contrived to open communication with him again, and letters were passed through the window (to which the prisoner had made a false and movable frame) and forwarded to Trenck's rich friends. His appeal was always answered promptly and amply. More valuable than money were two files, also procured from Gefhardt, and by their means the new chains were speedily cut through, though, as before, without any apparent break. Having freed his limbs, he began to saw through the floor of his cell, which was of wood. Underneath, instead of hard rock, there was sand, which Trenck scooped out with his hands. This earth was passed through the window to Gefhardt, who removed it when he was on guard, and gave his friend pistols, a bayonet, and knives to assist him when he had finally made his escape.
All seemed going smoothly. The foundations of the prison were only four feet deep, and Trenck's tunnel had reached a considerable distance when everything was again spoiled. A letter written by Trenck to Vienna fell into the hands of the governor, owing to some stupidity on the part of Gefhardt's wife, who had been intrusted to deliver it. The letter does not seem to have contained any special disclosure of his plan of escape, as the governor, who was still Duke Ferdinand of Brunswick, could find nothing wrong in Trenck's cell except the false window-frame. The cut chains, though examined, somehow escaped detection, from which we gather either that the officials were very careless, or the carpenter very stupid. Perhaps both may have been the case, for as the Seven Years' War (against Austria) was at this time raging, sentinels and officers were frequently changed, and prison discipline insensibly relaxed. Had this not been so, Trenck could never have been able to labor unseen, but as it was, he was merely deprived of his bed, as a punishment for tampering with the window.
As soon as he had recovered from his fright and an illness which followed, he returned to his digging.
It was necessary for him to bore under the subterranean gallery of the principal rampart, which was a distance of thirty-seven feet, and to get outside the foundation of the rampart. Beyond that was a door leading to the second rampart. Trenck was forced to work almost naked, for fear of raising the suspicions of the officials by his dirty clothes, but in spite of all his precautions and the wilful blindness of his guards, who as usual were on his side, all was at length discovered. His hole was filled up, and a year's work lost.
The next torture invented for him was worse than any that had gone before. He was visited and awakened every quarter of an hour, in order that he might not set to work in the night. This lasted for four years, during part of which time Trenck employed himself in writing verses and making drawings on his tin cups, after the manner of all prisoners, and in writing books with his blood, as ink was forbidden. We are again left in ignorance as to how he got paper. He also began to scoop out another hole, but was discovered afresh, though nothing particular seems to have been done to him, partly owing to the kindness of the new governor, who soon afterward died.
It had been arranged by his friends that for the space of one year horses should be ready for him at a certain place on the first and fifteenth of every month. Inspired by this thought, he turned to his burrowing with renewed vigor, and worked away at every moment when he thought he could do so unseen. One day, however, when he had reached some distance, he dislodged a large stone which blocked up the opening toward his cell. His terror was frightful. Not only was the air suffocating, and the darkness dreadful, but he knew that if any of the guards were unexpectedly to come into his cell, the opening must be discovered, and all his toil again lost. For eight hours he stayed in the tunnel paralyzed by fear. Then he roused himself, and by dint of superhuman struggles managed to open a passage on one side of the stone, and to reach his cell, which for once appeared to him as a haven of rest.
