“Will you two come with Wallace and me?” I asked our new friends one day. “I should like to have your help in getting out of camp,” I explained. “Later on I can probably be as useful to you.” And I referred to my record as an escaper, to my equipment, and to my _maps_. They assented. They knew from previous discussions that I was not entirely in sympathy with their proposed route; or, rather, I had explained to them what I thought to be the advantages of a route I had in mind, which were confirmed by their own information. As it appeared desirable that each member of the proposed expedition should be fully equipped as far as essentials were concerned, we set to work feverishly making tracings of parts of our maps. We had to finish this work while still in prison, because it would not be possible to secure sufficient privacy in Ruhleben for this kind of thing. Fortunately I had anticipated something like this months before, and possessed some colored inks and drawing-pens. Tracing-paper I manufactured from thin, strong white paper, which I treated with olive-oil and benzene. We finished three copies before we left prison, the original making the fourth. On the 23rd of August, 1917, a strong guard of policemen escorted a highly elated batch of British civilian prisoners through a part of Berlin, then by rail to Spandau, and again, _per pedes apostolorum_, to Ruhleben camp. We were nineteen in all. Four Britishers stayed behind voluntarily; five more were in “solitary,” having recently tried to escape and failed. Among the latter was our old friend L. CHAPTER XX RUHLEBEN AGAIN We arrived in Ruhleben shortly before noon, and were kept waiting for a long time just inside the gates, for the good of our souls. But then, the under dogs are always kept waiting somewhere for the good of their souls. So that was all right. When our names had been called a number of times, and some supposedly witty remarks had been made by a sergeant, whose reputation in camp was no better than it should be, we were marched off to our barracks (No. 14), a wooden one, and the last one toward the eastern end of the camp, next to the “Tea House.” Part of it was divided off by a solid partition and enclosed by a separate wire fence. This was the punishment place of the camp, called “the Bird Cage.” The other and larger part was empty; had, in fact, been cleared that morning for our reception, much to the disgust of the former inhabitants, who had been very comfortable in their home-made cubicles and corners. Now the place was absolutely bare, except for the litter of broken shelves and partitions on the floor.
