were accumulating outside of the gym. The guard then called a search, and then found the escape tunnel.[49] When the guards found the shaft they called an Appell and Hauptmann Schmidt confidently stated to the prisoners, "It is impossible to escape by tunnel or any other way." This wooden horse gym escape tunnel was two years prior to the famed Sagan wooden horse escape. Tunstall stated that he would like to think some of the watchers and workers who helped on their original wooden horse escape may have mentioned it from time to time; and would like to think that their idea contributed to the success of the effort at Sagan.
