Blind as to our movement of troops, and mistaken by fifty miles as to where his line was to be assailed, the enemy’s plight was further accentuated by the destruction of his communications on the very evening of the bombardment. Pulling out at night from their sham camp near Amman, the Arabs rushed away up north, and cut the railway and telegraph communications between Deraa and the great Turkish base at Damascus. This left the enemy on his whole front without supplies for the fight. Other telegraph lines further west were severed at the same time, and a bomb from an Australian plane on the night before our advance destroyed his great forward telephone exchange at Nablus, which dislocated all his lateral communications. When our guns opened at dawn on 19th September, the Turks were already in a desperate plight. THE NIGHT BEFORE On the night before the bombardment there was an atmosphere of perfect confidence in our camp close behind the line. Every man was moved by the prospect of a successful adventure, which would give vast immediate results and have an incalculable influence on the world war. The tropical intensity of Jordan Valley, where the Australian Brigades, with one exception, and some of the British and Indian cavalry had spent the whole summer, had left its mark. We had suffered much from malaria and other fevers, which, it was feared, might recur when we moved into the cooler north. The horses were, if not in poor condition, certainly on the light side; but these things were forgotten as the critical day approached. The Australian Mounted Division, commanded by Major-General Hodgson, and now made up entirely of Light Horse, except for one dashing, picturesque regiment of French Colonial regulars, had recently been armed with swords. The period of training in the new arm was very brief—for many Regiments only a few hours; but the men taking very keenly to it, soon reached a high standard of efficiency. Every trooper was excited at the thought of a true cavalry charge. The Anzac Mounted Division was still in the line in Jordan Valley.
