At 16:15, five minutes after the 159th (Cheshire) Brigade captured the Clay Hill redoubt near Ali Muntar, the attack on Gaza from the north by the Anzac Mounted Division's 2nd Light Horse Brigade, supported by the Somerset artillery battery, had not been seriously engaged until they reached the cactus hedges. Here they were strongly resisted in close, intense fighting. The cactus hedges had forced the light horsemen to dismount, however, the assault soon developed and progress was rapid. The 2nd Light Horse Brigade was supported by the New Zealand Mounted Rifles Brigade, which moved forward with the Canterbury Mounted Rifle Regiment in advance, and the Wellington Mounted Rifle Regiment in support. However, only three troops of the Auckland Mounted Rifle Regiment were in position, the remainder being delayed in the mounted screen, by strong hostile columns of reinforcements advancing from Huj and Nejed.
