On each side of the commandant's office, therefore, were the barrack rooms inhabited by the British officers, and to go from one side to the other it was necessary to pass the sentry standing at his post on the landing in between. From here a flight of steps gave on to the road through the main archway; on the other side of this again, and facing the stairs, was the door of the ground-floor barrack room used by our guard. This room was similar to those in the upper storey already described, and we found out by looking through a hole made for the purpose in the floor of the room above, and by casual visits when we wanted an escort for the bazaar, that the rifles of the occupants were kept in a row of racks on either side of the central passage-way.
By 6 A.M. on each morning of the first fifteen days of May every one was to be dressed, but those who had no specific job to do were to get back into bed again in case suspicion should be caused in the mind of any one who happened to come round. The aeroplanes, if they came, would arrive from the south. Two look-out parties of three, therefore, were to be at their posts by 6 A.M., one in the officers' mess in the S.E., and the other in the Padre's room next to the chapel in the S.W. corner of the barracks.
The staircases at these two corners of the square were to be watched by two officers told off for the purpose, one in each half of the north wing. When the look-outs in the south wing had either distinctly heard or seen an aeroplane, they were to come to their staircase and start walking down it into the square. Our look-outs in the north wing would warn the others in their rooms to get ready, and the officer who had the honour of doing verger to the Padre, and who used to ring a handbell before services, would run down the north-eastern staircase and walk diagonally across the square towards the chapel, ringing the bell for exactly thirty seconds.
The stopping of the bell was to be the signal for simultaneous action. The sentry on the landing could be easily disposed of by three officers; most of the rest were to run down certain staircases, cross the archway, dash into the barrack room and get hold of all the rifles, a small party at the same moment tackling the sentry at the main entrance.
On seeing the rush through the archway the look-out parties from the south wing would overpower the sentry in the square. The arms belonging to the three sentries and one other rifle were to be immediately taken to the corners of the barracks and the outside sentries covered. The orderlies, under an officer, would meanwhile form up in the square as a reserve.
Surprise was to be our greatest ally, and we hoped that, within a minute of the bell stopping, the barracks would be in our hands.
Having herded our Turkish guard into a big cellar and locked them in, we would then signal to the aeroplanes that the barracks were in our possession by laying out sheets in the square; while small picquets, armed with Turkish rifles and ammunition, would see to it that the aeroplanes on landing would be unmolested from the village. We are still convinced that the plan would have succeeded.
Even those in the know, however, put little faith in the probability of the aeroplane scheme being carried out, realising that the machines necessary for such an enterprise were not likely to be available from the main battle-fronts. Preparations, therefore, continued for working out our own salvation, as though this plan for outside help had not entered our heads. With the first signs of spring the tunnel scheme began to take concrete form.
As already mentioned in the description of the barracks, the ground to the west rose gently up to the Angora road. In this slope was a shallow, cup-like depression at a distance of forty yards from the building. If only a convenient point for starting a tunnel could be found in the nearest wall, the cup would form an ideal spot for breaking through to the surface. A night reconnaissance was made in the downstairs room on the western side of the barracks. As a result of this there seemed a likelihood that under the whole of the platform in this room we should find a hollow space varying from one to three feet in depth. If the surmise were correct and a tunnel could be run out from here, there would be no difficulty in getting rid of all the excavated earth into this hollow space. Unfortunately the lower room, though not in use, was kept locked.
