Two labourers who were building a small shed in the camp I steadily plied with cigarettes till they got quite talkative. They, too, had noticed the aeroplanes which flew daily over the camp. In the hope of getting detailed information from them, I tried a bluff which completely took them in. I asked them what had happened to the pilot who had passed over the camp two days before and had then crashed at X. At the same time I pointed in a direction in which I knew there was certainly no aerodrome. The story of the crash was, of course, an invention of my own. As I had expected, they shook their heads incredulously and declared emphatically that no pilot had crashed yet. Besides, they added, there was no flying ground in that direction; the two nearest aerodromes were at L. and U. In confirmation of their statements they described exactly the direction and distance. When I contradicted them—went so far as to suggest laughingly that they did not know the geography of their own country—they offered to prove their statements by means of a map. And next day they actually brought a beautiful big cycling map. After acknowledging my mistake I quietly dropped the map in my pocket during the course of the conversation which ensued. The trick had worked splendidly. I presented them with a number of cigars and then disappeared with my map.
The camp was now too small to accommodate the ever-increasing number of prisoners. A number of huts were therefore built on what had hitherto been the recreation-ground. It therefore became necessary to enlarge the recreation ground. The work had been begun during the winter and was finished in the early spring. The new ground, which adjoined the old one, was also surrounded by a wire entanglement and several sentry-boxes. It was to be opened only during the day time and to be closed at sunset. At the far end we were allowed to make two tennis-courts. The tools had to be handed in every evening.
In order to keep up the rôle of the 'sick man,' I took no part in any sort of sport or physical exercises. But I followed with the keenest interest the progress of the work on the tennis-courts. My plan was now fixed. I asked my friends who were looking after the tennis-courts to make a gully, on the side farthest from the camp, for the rain-water to drain off. This gully was to be gradually and unobtrusively widened and deepened so that two men could lie in it. The construction of this drain was, after some hesitation, sanctioned by the commandant, and was supervised by him and his officers. In this way the sentries got the impression that there was no objection on the commandant's part to the drain, and they suspected nothing when the prisoners worked at it again a few weeks later. This time, of course, without the colonel's sanction. As no spades or shovels were available preserve-tins cut and flattened out were used instead. Progress with these tools was, of course, very slow.
Fate decreed that at this time a young flying-man, Flight-Lieutenant Winkelmann, was brought to the camp. He had been shot down a short time before on the Western front, and had all sorts of interesting news to tell us. So many new officers were arriving now at the camp, some of them during the night, that it was often weeks after their arrival that one got to know them. This happened here. One day W. spoke to me. We introduced ourselves, and W. asked me without any circumlocution if it was true that I was thinking of bolting. When he noticed my surprise he added in explanation that he was a pilot and was extremely anxious to join me. As a trained fighting pilot, but with no knowledge of English to help him in a journey by road, he regarded my plan of escaping by aeroplane as the only one possible for him.
He knew all the modern machines, he said, and had often flown captured English aeroplanes behind the lines. I, on the other hand, knew the country and the people, and could speak the language. In this way we should be mutually complementary!
No sooner said than done. With more enthusiasm than ever I now worked in conjunction with W. in making all the necessary preparations.
I knew that several other groups of officers were also planning to escape. But I considered my scheme the most hopeful and was therefore anxious to anticipate the others, so that they should not wreck my chances.
In order the better to lull the suspicions of the English, I founded a theatre and undertook the duties of director.
As manager of this fine company I was in daily contact with the camp authorities, for I had to obtain their approval for every trifling arrangement. But the English appeared to be still suspicious, for one evening, after the orderly officer with his escort had passed through the hut and counted all the inmates, I heard him expressly ask the sentry on the door, 'Is Lieutenant Spindler there also?'
This business made me anxious, especially as it was repeated for a few nights. In about four weeks' time the drain ought to be big enough to conceal us. Luckily the big opening was somewhat hidden by tall grass which grew along the edge.
