We had been in Turkey for less than a year when we first established code correspondence with England. All our letters were censored in Vienna as well as in Constantinople, and perhaps locally; but, so far as we know, our code was never discovered. It was suspected, at least, some means of communication was suspected, because the Turkish Government was requested, through the Dutch Embassy, to set right certain urgent wrongs, and they knew that some one of us must have reported those wrongs. Letters frequently used to arrive with the marks of a hot iron on them, showing that they had been tested for at least one form of invisible writing. There are many forms of invisible writing, but we did not use them. We used a plain, straightforward code, and our letters might have been read by anyone on earth. It was curious that none of us should have arranged a code before leaving home, but no one had, and I never yet met a prisoner who had even contemplated the idea of being captured. Since our correspondence, after passing through several hands and various different addresses in England, eventually reached the War Office, it is obviously impossible for me to describe it. But I should like, however anonymously, to pay a tribute to the clever person who received the first code letter, realized that it was code, discovered the key to it, knew what to do with it, and acted as our central post office for the two and a-half years. He (she) had no idea that a code message was coming, and had no clue beyond what his (her) brain afforded. It is a pleasure, too, to be able to claim that, though immobilized, we were not altogether useless. What exactly they would have done with us if they had brought home to us a charge of conveying information of military value, I do not know. The most probable fate would have been a dungeon until the end of the war, or for as long as one could stand it. But, though I am unable to make further reference to the system we actually used, it may not be completely without interest to give an example of what can be done in the simplest possible way. For instance, a prisoner writes the following letter:-- DEAR ELIJAH It is four months now since you wrote to me about the proposed division of Dad’s property, and I have not had a single line since. If I am passed over because I am away it will be very hard, through no fault of my own. I don’t think that Gwendoline will be greedy enough to treat me as you say. And anyhow I rely upon you to do your best to bag the old hall clock for me. Dear old Dad always meant it for me, and it seems only yesterday that he promised me it, &c. &c. That is simple enough. It would pass any censor. But it contains military information. It is not the code we used, but it was, as a matter of fact, one which was held in reserve as a possibly useful one. It was never communicated home.
