Across the ribbon of the Dardanelles, on the green plain of Troy, the most famous war of the ancient world had been fought. The European shores had now become a no less classic ground of arms. If the banks of Scamander had seen men strive desperately with fate, so had the heights of Achi Baba and the loud beaches of Helles. Had the fashion continued of linking the gods with the strife of mankind, what strange myth might not have sprung from this rescue of the British troops in the teeth of winter gales and uncertain seas I It would have been rumoured, as of old at Troy, that Poseidon had done battle for his children. *CHAPTER XIX.* *THE CAPTURE OF JERUSALEM.* At the outset of the war the conquest of Egypt was an important aim of the Turkish Government and their German masters. But early in 1915 the Turkish invasion was scattered on the banks of the Suez Canal, and hopes of an easy victory were shattered. Nevertheless, the defence of Egypt remained an anxious problem for Britain. That country was the base both for Gallipoli and for Mesopotamia, and moreover, as Moltke pointed out long before, was the key of Britain’s Eastern possessions. It was soon realized that Egypt could not be properly defended on the Canal, but only on the Palestine frontier, beyond the Sinai Desert. During 1915 and 1916 Turkey and Germany projected many schemes for an Egyptian invasion, and the British generals in Egypt were no less busy. If the war was to be carried into Palestine railways and water pipes must be laid across the desert. Slowly the British front crept eastward. The Turks were defeated in various desert battles, and in the spring of 1917 the British army crossed the frontier of Palestine. The British purpose had somewhat changed. The offensive had been substituted for the defensive. So far as possible it was desired to do in Palestine what Sir Stanley Maude was doing in Mesopotamia—to pin down large Turkish forces, and so alarm Turkey about the safety of certain key points in her territory that she would demand aid from Germany and thus confuse the plans of the German General Staff.
