The concentration was worked to a time-table. Not only were brigades allotted certain marches each night, but they were given specified times to cover certain distances, and these were arranged according to the condition of the ground. In parts it was very broken and covered with loose stones, and the pace of infantry by night was very slightly more than one mile per hour. The routes for guns were not chosen until the whole country had been reconnoitred, and it was a highly creditable performance for artillery to get their field guns and heavy howitzer batteries through to the time-table. But the clockwork precision of the movements reflected even more highly on the staff working out the details than on the infantry and artillery, and it may be said with perfect truth that the staff made no miscalculation or mistake. The XXth Corps staff maps and plans, and the details accompanying them, were masterpieces of clearness and completeness. The men who fought out the plans to a triumphant finish were glad to recognise this perfection of staff work.[1] [Footnote 1: See Appendix VI.] CHAPTER VII THE BEERSHEBA VICTORY The XXth Corps began its movement on the night of 20-21st October. The whole Corps was not on the march, but a sufficient force was sent forward to form supply dumps and to store water at Esani for troops covering Desert Mounted Corps engineers engaged on the development of water at Khalasa and Asluj. Some of the Australian and New Zealand troops engaged on this work had previously been at these places. In the early summer it was thought desirable to destroy the Turkish railway which ran from Beersheba to Asluj and on to Kossaima, in order to prevent an enemy raid on our communications between El Arish and Rafa, and the mounted troops with the Imperial Camel Corps had had a most successful day in destroying many miles of line and several bridges. The Turks were badly in need of rails for the line they were then constructing down to Deir Sineid, and they had lifted some of the rails between Asluj and Kossaima, but during our raid we broke every rail over some fifteen miles of track. Khalasa and Asluj being water centres became the points of concentration for two mounted divisions, and the splendid Colonials in the engineer sections worked at the wells as if the success of the whole enterprise depended upon their efforts, as, indeed, to a very large extent it did. Theirs was not an eight hours day. They worked under many difficulties, often thigh deep in water and mud, cleaning out and deepening wells and installing power pumps, putting up large canvas tanks for storage, and making water troughs. The results exceeded anticipations, and the Commander-in-Chief, on a day when the calls on his time were many and urgent, made a long journey to thank the officers and men for the work they had done and to express his high appreciation of their skill and energy.
