After the Ridge had been captured, the enemy were pursued with all the fire from rifles, machine guns and artillery that could be brought to bear. Cavalry, or even infantry pursuit across these mountains was out of the question. An outpost line was established and the troops settled down to a wet and somewhat cheerless night. The mountain sides had been so steep that it had been impossible to bring up any comforts, and even the camels bearing the reserve supply of ammunition could only be got forward with extreme difficulty. Except for shelling, we were left unmolested during the night and next morning, which gave us the opportunity of constructing sangars, making tracks for the pack transport animals, and generally making ourselves more comfortable. Patrols were sent forward, and it was ascertained that the country to our immediate front was clear of the enemy. The effect of this advance was to draw down reinforcements into this sector, and to divert into Palestine reserves of Turkish troops; these came largely from the Caucasus, where the total collapse of Russia had set many good Turkish troops at liberty. There was evidence that these troops had been intended for an offensive campaign in Mesopotamia. It is probable, therefore, that this advance, indirectly, yet substantially, contributed to the defence of Mesopotamia, for the Turkish offensive in that area never materialized. Two or three German Divisions came down to stiffen up the Turks, and from this time forward the resistance which we had to face became unmistakeably hardened. The days of campaigning _de luxe_ had gone for ever. Before our "archies" could get forward, the Hun aeroplanes had very much their own way, and, flying low, dropped bombs and machine-gunned us in a manner that was most uncomfortable. Enemy artillery shelled any movements on the forward slope, and brought a searching fire to bear, in the hope of damaging our bivouac areas behind the crest. The manner in which the front line was held in the mountains by the Turks as well as by ourselves, was as follows. Strong sangars were constituted on the forward slope of a hill or ridge. By day these were occupied only by a small and well-protected observation party, at times supplemented with a Lewis gun team; and the remainder of the garrison were withdrawn behind the crest to bivouac areas on the reverse slope. At dusk, the garrison moved forward and manned the front line, being withdrawn again during the half-light of dawn. Thus the hostile artillery could never see a target upon which to fire. Searching a steep reverse slope with guns is almost impossible while, even with howitzers, unless observation can be obtained, an enormous amount of ammunition has to be fired to secure any result.
