or even reverse the effects of shock. Casualties were transported from the regimental aid post close to the firing line to an advanced dressing station in the rear by the stretcher bearers of the field ambulances attached to the light horse and mounted brigades. Evacuations back to the railway line which stretched across the Sinai, were undertaken in horse-drawn ambulances, in sand sledges or in cacolets on camels, which was described as "a form of travel exquisite in its agony for wounded men because of the nature of the animal's movement". Condition of the horses There was a progressive improvement in horsemanship during the summer and autumn of 1916 indicated by the small number of animals evacuated from the Anzac Mounted Division after the strenuous marching and fighting from August after the Battle of Romani, during the capture of El Arish and the Battle of Magdaba. This improvement was augmented by regular inspections by administrative veterinary officers when the advice offered was followed by regimental commanders. During the year the average loss of sick horses and mules from the Sinai front was approximately 640 per week. They were transported in train loads of thirty trucks, each holding eight horses. Animals which died or were destroyed while on active service were buried from the nearest camp unless this was not practicable. In this case the carcasses were transported to suitable sites away from troops, where they were disembowelled and left to disintegrate in the dry desert air and high temperatures. Animals which died or were destroyed in veterinary units at Kantara, Ismalia, Bilbeis and Quesna were dealt with in this way and after four days' drying in the sun, the carcases were stuffed with straw and burnt, after the skins were salvaged and sold to local contractors. Creation of Eastern Frontier Force In September 1916, General Murray moved his headquarters from Ismailia on the Suez Canal back to Cairo in order to deal more efficiently with the threat from the Senussi in the Western Desert. General Lawrence was transferred to France where he served as Chief of Staff to Field Marshal Haig in 1918. Field Marshal William Robertson, the Chief of the Imperial General Staff, set out his global military policy at this time in a letter to Murray of 16 October 1916, in which he stated "I am not intent on winning in any particular quarter of the globe.
