On the night of March 25 we got word that the long-expected attack would take place next morning. We had the cars ready to move out by three. Since midnight shadowy files had been passing on their way forward to get into position. One of our batteries went with the infantry to advance against the main fortified position at Khan Baghdadi. The rest of us went with the cavalry around the flank to cut the Turks off if they tried to retreat up-stream. We were well on our way at daybreak. The country was so broken up with ravines and dry river-beds that we knew we had a long, hard march ahead of us. Our maps were poor. A German officer that we captured had in some manner got hold of our latest map, and noting that we had omitted entirely a very large ravine, became convinced that any enveloping movement we attempted would prove a failure. As it happened, we came close to making the blunder he had anticipated, for we started to advance down to the river along the bank of a nullah which would have taken us to Khan Baghdadi instead of eight or ten miles above it, as we wished. I think it was our aeroplanes that set us straight. I was in charge of the tenders with supplies and spares, and spent most of the time in the leading Napier lorry. Occasionally I slipped into an armored car to go off somewhere on a separate mission. The Turks had doubtless anticipated a flanking movement and kept shelling us to a certain extent, but we could hear that they were occupying themselves chiefly with the straight attacking force. By afternoon we had turned in toward the river and our cavalry was soon engaged. The country was too broken for the cars to get in any really effective work. By nightfall we hoped we were approximately where we should be, and after making our dispositions as well as the circumstances would permit, we lay down beside the cars and were soon sound asleep. At midnight we were awakened by the bullets chipping the rocks and stones among which we were sleeping. A night attack was evidently under way, and it is always an eerie sensation. We correctly surmised that the Turks were in retreat from Khan Baghdadi and had run into our outposts. In a few minutes we were replying in volume, and the rat-tat-tats of the machine-guns on either side were continuous. The enemy must have greatly overestimated our numbers, for in a short time small groups started surrendering, and before things had quieted we had twelve hundred prisoners. The cavalry formed a rough prison-camp and we turned in again to wait for daylight.
