Despite these problems, 76 men crawled through to freedom, until at 4:55 a.m. on 25 March, the 77th man was spotted emerging by one of the guards. Those already in the trees began running, while a New Zealand Squadron Leader Leonard Henry Trent VC who had just reached the tree line stood up and surrendered. The guards had no idea where the tunnel entrance was, so they began searching the huts, giving men time to burn their fake papers. Hut 104 was one of the last to be searched, and despite using dogs the guards were unable to find the entrance. Finally, German guard Charlie Pilz crawled back through the tunnel but found himself trapped at the camp end; he began calling for help and the prisoners opened the entrance to let him out, finally revealing its location.
