The main attack, from the north and east, was to be made by the New Zealand Mounted Rifles Brigade, commanded by Brigadier General Edward Chaytor, which moved in line of troop columns. The New Zealanders were supported by a machine gun squadron armed with Vickers and Lewis guns, and the 3rd Light Horse Brigade all under the command of Chaytor. This attack began near the village of Magdhaba and the Wadi El Arish, on the virtually featureless battleground, when the British Empire artillery opened fire at the same time as Chaytor's group moved towards the Ottoman garrison's right and rear.
