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 towards Bohemia, they changed their course and pushed on to the river Neiss, at this season partly covered with ice. Trenck swam over slowly with this 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 recognised 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 neighbouring town of Wunschelburg a hundred soldiers were quartered, with orders to capture all deserters from the fortress. This time, however, fortune favoured 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.
