Where we were going to nobody save those in command knew; most of us were too weary to care. Our deadened senses were hardly capable of realising that the relieving Turks had somewhere broken through the cordon; we had to clear out and, in spite of what the firing had told us at sundown, we had failed to take Gaza. That much was now obvious; victorious troops do not as a rule retreat, especially at our present pace.

Hence we had no option but to keep moving as fast as we could until we were ordered to stop.

A mile or two out of the nullah we encountered the rest of the brigade, and gradually a troop from one unit or a squadron from another joined the column. By now it was pitch dark, but as far as one could judge we were taking a different route from that by which we had come. Our present direction was due west, and had we persisted in following it this route would have led us straight into the Turkish lines at Gaza.

The reason, which I give with some reserve, was learnt later. A German officer speaking perfect English and dressed in the uniform of a British staff-officer, rode up to the head of the column and announced that he had been sent by Headquarters as a guide. Thereupon the column followed this audacious gentleman's leadership for some miles, until a pukka British officer, who had providentially spent some years surveying this very country, asked his commander whether he knew that we were making a bee-line for the Turkish defences. A startled ejaculation burst from the general, who turned to the guide to ask him if he was quite sure of the way.

But he asked in vain, for the man had disappeared!

Whether this explanation be true or no, there are in connection therewith two somewhat significant points: one was that some days later a German, masquerading as a British staff-officer, was undoubtedly captured, and paid the customary penalty; the other was that after we had trekked for perhaps a couple of hours in a westerly direction, we turned sharply to the left and continued almost due south, at right angles to our previous route.

We had not proceeded far this way when we came across the remainder of the mounted divisions, and fell in beside them, a heterogeneous mass. Troopers of the Light Horse were riding with gunners from the artillery; cacolet camels, whose native drivers had their heads shrouded in blankets, trudged beside ambulance carts; here and there a man who had lost his horse stumbled wearily along, first in one column then in another; guns and ammunition-limbers were mingled with cable-waggons; and all followed blindly man or waggon in front of them. The army slept as it marched. Men slid gradually down into the saddle, with bowed heads, until the tired horses stumbled and jerked them again into a hazy consciousness for a few yards. Then the heads drooped once more, the nerveless hands loosed the reins, and bodies swayed unevenly back and forth. Here and there a man, utterly overcome by sleep, lurched from his saddle, pitched headlong and lay where he had fallen until one more wakeful picked him up and set him on his waiting horse again or in an ambulance. Some tied themselves on gun-limbers and slept there, while their riderless horses gregariously followed the column.

A slumbering, ghostly army, moving like automata. What sounds there were seemed to come from a great distance: the soft pad-pad of the camels, the creaking of the cacolets swaying high and low and the moans of the tortured men in them, the uneven beat of hoofs, and mingled with every sound was the monotonous crunching of waggon-wheels on the rough ground.

It was terribly difficult work for the drivers in the engineers and artillery, for the country now was broken by great boulders, dust rose in clouds obscuring the vision, and no semblance of a road was to be found. The lead-drivers had to keep a sharp look-out lest they ran down somnolent stragglers wandering across their path, and if the column halted suddenly they had to throw off quickly to one side to avoid running into the waggon immediately in front and telescoping the whole team. This was a particularly onerous task, for the dust made it impossible to see more than a yard or two ahead. The wheel-drivers were in no better case and in addition they had the waggon-pole to look after, and the centre-drivers were betwixt the devil and the deep sea.

Besides the rough country there were deep, narrow nullahs to be crossed, some of them with sides as steep as the roof of a house. Then the wheel-drivers reined in till the pole-bars almost lifted the weary horses from the ground, and those in front picked a perilous way step by step over the rocky surface of the incline.
