The EEF was reinforced by the arrival in June and July of the 7th and 8th Mounted Brigades and the 60th (London) Division, transferred from Salonika; the 75th Division was formed in Egypt from Territorial and Indian battalions. The arrival of the two mounted brigades, made it possible to expand and reorganise the Desert Column into three divisions (with the establishment of the Yeomanry Mounted Division). However, 5,150 infantry and 400 yeomanry reinforcements were still needed in July to bring the infantry and mounted divisions that had taken part in the first two battles for Gaza, back up to strength. The last reinforcements to arrive before the battle, the 10th (Irish) Division, were marching north from Rafa on 29 October.
