In preparation for the attack, against Jerusalem, the ANZAC Mounted Division and the 54th (East Anglian) Division, would form a defensive line on the coastal plain, while the XXI Corps moved into the Judaean Mountains. Instead of a direct assault on Jerusalem, Allenby planned to first cut off the city from their supply routes in the north. The plan was for two infantry division, the 75th Division on the left, the 52nd (Lowland) Division in the centre, with the horsemen from the Yeomanry Mounted Division on the right, to move on Jerusalem with the 75th using the main Jaffa-Jerusalem road. The two outer division's would circle around Jerusalem meeting at Bireh to the north of the city.
