However well the Navy and all associated with it worked, only a very small proportion of the Army's supplies was water borne. The great bulk had to be carried by rail. Enormously long trains, most of them hauled by London and South-Western locomotives, bore munitions, food for men and animals, water, equipment, medical comforts, guns, wagons, caterpillar tractors, motor cars, and other paraphernalia required for the largest army which had ever operated about the town of Gaza in the thousands of years of its history. The main line had thrown out from it great tentacles embracing in their iron clasp vital centres for the supply of our front, and over these spur lines the trains ran with the regularity of British main-line expresses. Besides 96,000 actual fighting men, there was a vast army of men behind the line, and there were over 100,000 animals to be fed. There were 46,000 horses, 40,000 camels, 15,000 mules, and 3500 donkeys on Army work east of the Canal, and not a man or beast went short of rations. We used to think Kitchener's advance on Khartoum the perfection of military organisation. Beside the Palestine expedition that Soudan campaign fades into insignificance. In fighting men and labour corps, in animals and the machinery of war, this Army was vastly larger and more important, and the method by which it was brought to Palestine and was supplied, and the low sick rate, constitute a tribute to the master minds of the organisers. The Army had fresh meat, bread, and vegetables in a country which under the lash of war yielded nothing, but which under our rule in peace will furnish three times the produce of the best of past years of plenty. A not inconsiderable portion of the front line was supplied with Nile water taken from a canal nearly two hundred miles away. But the Army once at the front depended less upon the waters of that Father of Rivers than it had to do in the long trek across the desert. Then all drinking water came from the Nile. It flowed down the sweet-water canal (if one may be pardoned for calling 'sweet' a volume of water so charged with vegetable matter and bacteria that it was harmful for white men even to wash in it), was filtered and siphoned under the Suez Canal at Kantara, where it was chlorinated, and passed through a big pipe line and pumped through in stages into Palestine. The engineers set about improving all local resources over a wide stretch of country which used to be regarded as waterless in summer. Many water levels were tapped, and there was a fair yield. The engineers' greatest task in moving with the Army during the advance was always the provision of a water supply, and in developing it they conferred on the natives a boon which should make them be remembered with gratitude for many generations.
