“To reduce my labour as much as possible, I was constrained to make the passage so small that my body only had space to pass, and I had not room to draw my arm back to my head. The work, too, had all to be done naked, otherwise the dirtiness of my shirt would have been remarked; and the sand was wet, water being found at the depth of four feet, where the stratum of the gravel began. At length the expedient of sand bags occurred to me, by which it might be removed out and in more expeditiously. I obtained linen from the officers, but not in sufficient quantities. Suspicions would have been excited had too much linen been brought into the prison. At last I took my sheets, and the ticking that inclosed my straw, and cut them up for sand bags, taking care to lie down on my bed as if ill, when Bruckhausen paid his visit.
“The labour, towards the conclusion, became so intolerable as to excite despondency. I frequently sat contemplating the heaps of sand, during a momentary respite from work; and thinking it impossible I could have strength or time again to replace all things as they were, have resolved patiently to wait the consequences, and leave everything in its present disorder. Yes, I can assure the reader that to effect concealment, I have scarcely had time in twenty-four hours to sit down and eat a morsel of bread. Recollecting, however, the efforts and all the progress I had made, hope would again revive in me, and exhausted strength return, and again would I begin my labours; yet it has frequently happened that my visitors have entered a few minutes after I had reinstated everything in its place.
“When my work was within six or seven feet of being accomplished, a new misfortune happened, that at once frustrated all further attempts. I worked, as I have said, under the foundation of the rampart, near where the sentinels stood. I could disencumber myself of my fetters, except my neck collar and its pendant chain. This, as I worked, though it was fastened, got loose, and the clanking was heard by one of the sentinels, about fifteen feet from my dungeon. The officer was called, they laid their ears to the ground and heard me as I went backward and forward to bring my earth bags. This was reported the next day, and the major, who was my best friend, with the town major, and a smith and mason, entered my prison. I was terrified. The lieutenant, by a sign, gave me to understand I was discovered. An examination was begun; but the officers would not see, and the smith and mason found all, as they thought, safe. Had they examined my bed they would have seen the ticking and sheets were gone. The town major, who was a dull man, was persuaded the thing was impossible, and said to the sentinel, ‘Blockhead, you have heard some mole underground, and not Trenck. How indeed could it be, that he should work underground at such a distance from his dungeon?’ Here the scrutiny ended.
