The transport was now some miles on its way and the mule-drivers were doing their utmost. Then the Staff mounted and I was sent to see the whereabouts of the ammunition barge, as the guns, especially S Battery, were running short. Luckily, I discovered where it had got stuck. In feverish haste we replenished the carts ourselves, General Smith, the Staff Captain and I, our telephonists and horseholders, all loading the first few carts at the run. In less than five minutes the cute little Jaipur ponies and mules had galloped to their guns. The batteries remained in action as long as possible without jeopardizing their safety, and each covered the retirement of the other. This went on for hours. We, the Staff, walked our horses half a mile, dismounted and waited. Our pace was the pace of the slowest fighting unit, i.e. a walk. Gradually we out-distanced the enemy, the Cavalry Brigade keeping him back. Once they caught us up and sent shells wildly over our heads. The Turks don't know enough of the science of gunnery. If their fuses had been more correct our casualties could not have failed to be very heavy. As it was they were extraordinarily small considering the huge losses we inflicted on them.

It was a most wonderful engagement, and General Townshend watched its every phase with great satisfaction. An exclamation of delight broke from him as he directed our attention to a charge of the 14th Hussars. Over the brown of the desert a mass of glittering and swiftly-moving steel bore down upon the line of Turks, which broke and bolted. Then the 14th came back.

My next job was to gather spare men and protect the General's flank from Arab snipers. Once or twice a bullet hit the ground at my feet. These Arabs use a tremendous thing, almost as big as an elephant bullet.

At four o'clock I was ordered to ride ahead of the column to find a watering place, which I did; but the Turks still pressed in our rear, and we had to shove on without watering. I managed to water Don Juan, however, and gave him three of my six biscuits. The General had one and Garnett and I had half each. We pushed on, the horses showing signs of fatigue. At 6 p.m. it was dreadfully cold, and dark as Tophet. The order of the column had now been changed, the Field Artillery leading. The B.G.R.A. (General Smith), the Staff Captain, and I, rode at the head of the Division. The orders were seventy paces to the minute with compass directing. We took this in turns of half-hours. The strain was very severe. We had had no food except a sandwich for breakfast for twenty-four hours—violent exercise under exhausting conditions. The ten hours in the saddle had made me stiff, which was to be expected after the slack life of a month on board. We lost our way again and again as we got deeper into the dense black night. Road there was none, only a few hoof marks on the maidan. Tracks that went comfortably for a mile suddenly proved false, and then we had to hunt for the road. We all grew more irritable as we grew more tired, and I got an awful wigging about every two minutes. It's no joke leading an army on a pitch black night and endeavouring to keep to a road that doesn't exist, especially when thousands of Turks are in hot pursuit a mile or two behind the tail of the column.

"Is this the road?" asks one.

"I don't believe it is."

"I think he's wrong. He's taking that fire for the star."

"He must be wrong. That fire has been directly ahead for hours and now it's to the left."

This was the eternal conversation behind as one tried to count the seventy and answer inquiries as to the magnetic bearing at the same time. With such preoccupations one could not very well suggest that the nearer one got to the fire, the more to a flank it must appear unless we were to walk on the top of it.

Then arguments would follow as to whether such a mark were really a hoof-mark or wheel track. The Staff Captain lost his way several times running, and I confess my heart rejoiced thereat. But we soon passed from levity that was born of nervous exhaustion, to silence, grim and impenetrable. I shall never forget that night. The want of sleep was maddening. Since then I have gone without sleep for days together, except for an hour or so once or twice. Then it came on one unprepared. We stumbled on. I thought of the army behind us, men as tired and hungry as I was, the army that had conquered Mesopotamia, all bravely staggering onwards in the darkness; heroes of Ctesiphon, full of painful memories of lost pals somewhere behind, marching, marching, marching to the pace we set, and following the indication of my prismatic compass.
