 By about midday on 4 August, the Turkish and German force had pushed the two Australian brigades back to a point where the 52nd (Lowland) Infantry Division, in their trenches, were able to attack the Turkish right flank, and the New Zealand Mounted Rifles Brigade and British 5th Mounted Brigade arrived from their deployment protecting the Suez Canal, to extend the Australians' line on the left flank.The Turkish and German advance was stopped by the fire brought to bear on them by the combined British infantry and Australian, British and New Zealand mounted forces and the deep sand, the midday summer heat, and thirst.In these extremely tough conditions, the British infantry were unable to move effectively against the retreating German and Turkish force in the following days.
