I returned in triumph to my ward, and Robin and I laid our heads together. With the drugs we now possessed it would be possible to send our sentries to sleep when we were moved from hospital, if the person who was making plans for us to be taken on board a Black Sea steamer failed to communicate in time. But the question now arose as to how much of these drugs was suitable for the Turkish constitution. The object was to administer a sleeping draught, not a fatal dose. If we were transferred from Haidar Pasha we knew we should be sent for a time to the garrison camp of Psamattia (a suburb of Constantinople on the European side) and our intention was to inveigle our attendants into having lunch during our journey there, and ply them with Pilsener beer, suitably prepared, until they were somnolent and unsuspicious enough to make it feasible to bolt. Neither the bromide nor the trional could be tasted in cocoa or coffee, we discovered, so one evening, I regret to say, I carried out an experiment on a wounded patient, who was otherwise quite fit, although rather sleepless, by giving him a cachet of bromide and a tablet of trional in a cup of cocoa. In about half an hour his eyelids began to flicker, and he was soon sleeping like a lamb. Next morning he complained of a slight headache. Should he chance to read these lines I hope he will accept my apologies. _A la guerre comme a la guerre._ So now we had the beginning of a second plan, in case the box business _via_ the Black Sea failed. But, in the event of escaping during our journey to Psamattia, we had no very clear idea of where to hide. That there were Greek and Jewish quarters in Galata and in Pera we knew, and also in the northern part of Stamboul, but the chances of detection in any of these localities were great, especially as we had no disguises at the time. There remained a possibility of hiding in the ruins of recent fires, but it was difficult to see how we were to live there. On the whole the Black Sea trip seemed to offer the most favourable opportunities of success. But to carry it out, we had to wait, and wait, and still to wait, until we heard from our agent again. And eventually the time came when we could wait no longer. . . .
