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.
