The country around Samarra is not unlike in character the southern part of Arizona and northern Sonora. There are the same barren hills and the same glaring heat. The soil is not sand, but a fine dust which permeates everything, even the steel uniform-cases which I had always regarded as proof against all conditions. The parching effect was so great that it was not only necessary to keep all leather objects thoroughly oiled but the covers of my books cracked and curled up until I hit upon the plan of greasing them well also. In the alluvial lowlands trench-digging was a simple affair, but along the hills we found a pebbly conglomerate that gave much trouble. Opinion was divided as to whether the Turk would attempt to advance down the Tigris. Things had gone badly with our forces in Palestine at the first battle of Gaza; but here we had an exceedingly strong position, and the consensus of opinion seemed to be that the enemy would think twice before he stormed it. Their base was at Tekrit, almost thirty miles away. However, about ten miles distant stood a small village called Daur, which the Turks held in considerable force. Between Daur and Samarra there was nothing but desert, with gazelles and jackals the only permanent inhabitants. Into this no man's land both sides sent patrols, who met in occasional skirmishes. For reconnaissance work we used light-armored motor-cars, known throughout the army as Lam cars, a name formed by the initial letters of their titles. These cars were Rolls-Royces, and with their armor-plate weighed between three and three-quarters and four tons. They were proof against the ordinary bullet but not against the armor-piercing. When I came out to Mesopotamia I intended to lay my plans for a transfer to the cavalry, but after I had seen the cars at work I changed about and asked to be seconded to that branch of the service. A short while after my arrival our aeroplanes brought in word that the Turks were massing at Daur, and General Cobbe decided that when they launched forth he would go and meet them. Accordingly, we all moved out one night, expecting to give "Abdul," as the Tommies called him, a surprise. Whether it was that we started too early and their aeroplanes saw us, or whether they were only making a feint, we never found out; but at all events the enemy fell back, and save for some advance-guard skirmishing and a few prisoners, we drew a blank. We were not prepared to attack the Daur position, and so returned to Samarra to await developments.
