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. 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.
