By noon, Chetwode was concerned that the strength of the opposition to the infantry attack, could make it impossible to capture Gaza before dark. As a consequence, he ordered Chauvel and Hodgson to reconnoitre towards Gaza, warning them to be prepared to supply one brigade each to reinforce the infantry attack. At 13:00 Chetwode put Chauvel in command of both mounted divisions, and by 14:00 Chauvel was ordering the whole of the Anzac Mounted Division to attack Gaza from the north, while the Imperial Mounted Division and Imperial Camel Brigade, supported by Nos 11 and 12 Light Armoured Motor Batteries and No. 7 Light Car Patrol, were to hold the outpost line and all observation posts. As the Anzac Mounted Division moved north, it was replaced in the mounted screen by the Imperial Mounted Division, which in turn was replaced by the Imperial Camel Brigade.
