Whether this letter ever reached His Excellency we shall probably never know. From our knowledge of the Turk's total lack of humour, however, we should say that it is more than probable that Tewfik Bey solemnly forwarded it on through the proper channel. That no answer was received proves nothing; for it is a matter of years to get a reply to an application like this from the authorities at Constantinople, and the letter was only written three years ago. At least it had this good effect, that the major was released from confinement forthwith.
But we must return to our real subject. Amongst the three officers from Geddos was one Tweedledum, so named from a certain rotundity of figure, which even the scanty provisions said to be obtainable there had failed to reduce. From his lips we first heard of the wonderful capabilities of the Handley-Page passenger aeroplane. Such machines, he said, could carry fifteen to sixteen passengers, and three of them had recently flown from England to Mudros, with only one intermediate landing in Italy. A pilot of one of them had been a prisoner with him at Geddos. A few evenings later Nobby had a great brain-wave; fetching a 'Pears' Annual,' he turned up the maps of Europe and Asia Minor, and, after a few hurried measurements, unfolded to his stable companions, Perce and Looney, what was afterwards known as the "aeroplane scheme." These three had, with much expense and trouble, managed to collect enough planks for a real wooden partition to their "room," and it was behind this screen that this and many another devilish plot was hatched.
Briefly, Nobby's idea was for a flight of five or six Handley-Pages to be sent from Cyprus, swoop down on Changri, and pick up the whole camp, both officers and men—and Sami too. We should, of course, have to take over the barracks from our guards, but this should be easily effected by a coup de main, and probably without having to resort to bloodshed. At first the idea appeared a trifle fantastic, for after being cut off from the outside world for two whole years it took time for us to assimilate the wonderful advance of aeronautical science which the scheme assumed; but given that Tweedledum's statement was correct, the scheme was feasible, and we soon took up the question seriously. Our representative of the R.F.C. pronounced the surrounding fields practicable landing grounds; a committee confirmed the possibility of taking over the barracks by surprise; and the whole scheme, illustrated by a small sketch of the vicinity, was soon on its way home.
We were fortunate in having a method of sending secret information without much risk of detection. The censorship of our letters, like most things in Turkey, was not very efficient. Looney's brother in England was the inventor of the secret means. The first code which he devised consisted merely of diminutive gaps between pairs of letters in an apparently ordinary communication. That there was a message contained was indicated to the addressee by the writer adding after his signature his address as "Codin House, Thislet Terrace."[6] The exact nature of the code then had to be discovered by guess-work. After two letters had been received, Nobby noticed the gaps, and the clue was discovered. By stringing together all the letters preceding the gaps, one obtained the concealed message.
The way thus opened, more effective means of communication could be developed. One of these was to send out messages written on a slip of paper, wrapped up in silver tissue and then inserted in a full tube of tooth-paste. As parcels, however, took anything from eight months to over a year to reach the camp, the value of the news contained was considerably diminished. Moreover, this method was not available for sending news from Turkey to England.
The final method was simple, yet perfectly effective for smuggling news into a country such as Turkey. It consisted of pasting together two thin post-cards, the gummed portion being confined to a border of about an inch in width round the edges. The central rectangle so left ungummed was available for the secret message, which was written very small on the two inner faces of the cards before they were stuck together. Further space for writing was obtainable by adding another slip of paper of the size of the rectangle, and including this within the cards when gumming them up. After being pressed, the final post-card was trimmed so as to leave no sign of the join. The position of the rectangle containing the message was indicated on the address side by at first two lines, and later by the smallest possible dots at the corners. Well over a score of such cards must have passed from England into Turkey, and more than half that number in the reverse direction, without discovery ever being made by our captors. In the camp, to avoid the risk of being overheard talking about "split post-cards" by one of the interpreters, these cards were known as "bananas"—an apt name, as you had to skin them to get at the real fruit inside!
This explains the method by which it was possible to suggest the aeroplane scheme to the home authorities.
Unfortunately it used to take at least four months to receive a reply to a letter. For this reason we could not afford to wait until a definite date was communicated to us, so we ourselves named the first fifteen days of May as suitable for us, and agreed, from 6 to 8 A.M. on each of these days, to remain in a state of instant readiness to seize the barracks should an aeroplane appear. For the sake of secrecy, the details of the coup de main itself were left to be worked out by a small committee, and the report spread amongst the rest of the camp that the scheme had been dropped. The true state of affairs would not be divulged until a few days before the first of May.
The committee's plan was this. There were at Changri 47 officers and 28 orderlies—a total force of 75 unarmed men with which to take over the barracks. Our guard, all told, numbered 70 men. At any one time during daylight there were seven Turkish sentries on duty: one outside each corner of the barracks, one inside the square which had an open staircase at each corner, one at the arched entrance in the centre of the north face, while the seventh stood guard over the commandant's office. This was a room in the upper storey over the archway and facing on to the square.
