my cocked Webley in my hand I called out. It proved to be an Arab who took to his heels and vanished like a wraith. He had probably been salvaging. I reached my dug-out very tired an hour later and found all the battery asleep. An order required me to stand by from four to six, so I slept with my boots on. At four I went around the battery and had the men standing to, which means awake and dressed ready for action but resting. Nothing happened. At dawn I was told to get my kit and report for duty at the Fort as Observation Officer to the Tenth Field Artillery Brigade, the other officer having been wounded the preceding day. Slinging a few things together to be brought along by my servant, I walked the two miles of trenches to the Fort, which I entered for the first time. It proved to be a mud-walled enclosure of about seven acres with a few bastions extending beyond. The garrison of the Fort were all underground and dug in. In fact, the place was a network of communication trenches, dug-outs, or store-pits. It was an easy target for the Turkish artillery, and shells of all sizes kept leisurely arriving from all sides, and at this close range we hadn't any warning report of the Turks' guns, besides which, grenades and bombs were slung or fired over the wall indiscriminately into any part of the Fort. In the centre an observation mound of bags of _atta_ (flour), some fifteen feet high, commanded quite an extensive view over the walls on to the plain beyond. One could see three-fourths of the horizon and a very good view of Turkish activities upstream. This observation post was frequently a mark for the Turkish machine-guns, and one had to run the gauntlet in getting up to it by making a sudden bolt, and frequently a r-r-r-rip of bullets into the flour-bags followed. Sometimes, generally during the firing of a series, the Turk ranged several machine-guns and small pounders on to the post. Besides myself there was an observer for the heavy guns. When registering we seized the most favourable hour of the day for the minimum of mirage, usually just after sunrise or before sunset. As the artillery duel became general, one had to range on several targets in succession and sometimes two simultaneously. When one was too preoccupied the services of the machine-gun officer were utilized. Although not trained for artillery observation, and talking of "degrees over" or "short," which frequently puzzled the gunners, he nevertheless had a good eye for a bursting shell. He was a big-game shot endowed with a large imagination and a bad memory, as he constantly varied the same story, but what one lost in veracity one derived in entertainment. I liked especially to get into the "stack," as we called it, at dawn, and watch the shadows lifting over the plain and the wild duck and fowl flying away to their feeding-grounds.
