When he had sufficiently recovered from the shock the trooper described what he had seen to the sentry, who urged him to go to bed and he would probably be better in the morning. However, the trooper persisted in his tale, and finally the sentry promised to keep a sharp look-out on the place and to warn his relief to do the same. The next day the trooper, his conviction still unshaken, collected a few friends and together they dug round the mysterious spot. They found an underground chamber with telephone apparatus complete, which was found to be connected with the Turkish defences at Gaza! The trap-door leading down to it was hidden under sods of earth indistinguishable from the surrounding soil and the place was ingeniously ventilated by a pipe through the stump of a tree close by. The two occupants had rations enough for a siege; only they knew how long they had been installed and how much information they had gathered. The sublime effrontery of the thing! It might have gone on for ever had not one of the prisoners crawled out for a breather at the precise moment when the convivial trooper was returning to home and friends. After this episode there was a long and rigorous hunt for spies and several more were captured, most of them carrying on very innocent-looking pursuits. What made the risk of detection less for these people was the British policy, in the main a sound one, of non-interference up to a certain point with the natives of the country in which we were fighting; any old Bedouin, therefore, was a potential spy. By the middle of April the preparations for a second attempt on Gaza were complete. This time there was no intention of confining the issue to a one- or even two-day battle. There might be another fog.... On the 16th we packed six days' rations and forage on to the limbers and moved to the outskirts of Belah, there to cover the infantry and wait till they had carried out their part of the programme, which was to capture the outer defences of Gaza. The Lowlanders and East Anglians did this in great style the next morning, and spent the rest of that and the following day consolidating the gains and preparing for the big "show" on the 19th. At dark on the 18th we moved forward and crossed the wadi once again: the journey this time was made comparatively easy by the fine work of the engineers during the past fortnight.
