Canal and the passage of shipping. Granted that a new line must be found, the question arises where such new line should be drawn. A line across the actual desert may be all very well in war time, though none too easy to hold, for the reasons that we have already discussed. But to keep a garrison on such a line for ever would be well-nigh intolerable. Thus, by a process of elimination, we find that the most suitable line for the permanent defence of the Suez Canal is the fertile country beyond the eastern desert--in other words, Palestine.
Fourthly, it had been brought home to us that the worst form of defence is a passive defence. As, therefore, the Turk would not leave well alone, but insisted on attacking us in Egypt, so it became necessary for us to meet him on his own ground, to push a vigorous offensive, and eventually to carry the war into Palestine.
CHAPTER II
THE DESERT OF SINAI
In accordance with the policy of defending the Suez Canal upon a line further east, the construction of a new defensive line was put in hand during the early months of 1916. No longer were the Turks to be allowed to annoy us by actually reaching the Canal. A line of trenches, protected by barbed wire entanglements, was constructed out in the desert, a few miles to the east of the Canal. As may be imagined, this was no easy task. A large amount of excavation was necessary for a small amount of trench; walls had to be built up with sandbags; and other steps had to be taken to prevent the sides from foundering, and to construct a work that would withstand shell fire.
Meanwhile, other preparations were put in hand for carrying the defensive line further to the east. The construction was commenced of a broad gauge of railway from Kantara eastwards across the desert. This railway eventually became the trunk line between Egypt and Palestine. In the days of trench warfare before Gaza, it transported freight trains heavily laden with rations and ammunitions, troop trains conveying officers and men in open trucks, hospital trains evacuating sick and wounded, and an all-sleeping-car express running nightly in each direction. In 1918, a swing-bridge was improvised across the Suez Canal, and Jerusalem and Cairo were then connected by rail without change of carriage being necessary. The future prospects of this railway seem unbounded. It will undoubtedly be continued through to Damascus and Aleppo, where it will connect with railways to Constantinople and to Baghdad and the Persian Gulf. Thus it will form part of a grand trunk railway system along the old caravan routes connecting the three continents of Europe, Asia, and Africa. In its conception, it was just a military railway, laid, with but little preparation, across the sands of the desert. To this railway, however, was largely due the success of the campaign that we are about to consider.
We have already seen that the Sinaitic Desert is almost waterless. Although it has often been crossed by invading armies in both directions, the provision of water has always presented the greatest difficulty. The carriage of water in tanks upon the backs of camels, a method used by us for locally supplying troops between water dumps and the headquarters of units, proved successful here thousands of years ago. The plan adopted by the Turks of dragging water-holding pontoons across the desert was not to be despised. Further progress was made when supplies of water were transported in tank-trucks along the railway. But a bolder adaptation of modern science to desert fighting was reached, when it was decided to lay on a piped supply of water from the Nile.
We have seen that the western bank of the Suez Canal was already provided with a plentiful supply of fresh water by the Sweet Water Canal. Plant was now installed for making this water available for the troops. Purity had to be considered as well as adequacy of supply. A peculiar danger had to be guarded against. There is a disease prevalent in Egypt, of a particularly unpleasant character and persistent type, called by the medical profession Bilhaziosis, but better known to our men as "Bill Harris." This disease is conveyed by a parasitic worm found in the waters of the Nile, and affects not only those who drink the water, but also those who bathe in it or merely wash. Consequently, orders were stringent against even touching Nile water which had not previously been treated. This necessitated the troops east of the Canal being put upon a very restricted supply, and they were accordingly rationed at the rate of a gallon of water per head per day for all purposes, including washing, cooking and drinking. At the Kantara waterworks water was drawn
