By 10:00, Chaytor ordered the 1st Light Horse Brigade to reinforce the attack on Tel el Saba from the south and cooperate in the attack. The brigade sent the 3rd Light Horse Regiment (1st Light Horse Brigade), with one subsection of a machine-gun squadron, to cover the New Zealanders' left flank. At 10:15 they made a "dashing advance" across the plain against artillery and machine-gun fire. Shortly afterwards two of the squadrons took up an exposed position on the bank of the wadi, covering the attackers' left flank. Heavy machine gun, Hotchkiss and rifle fire targeted the Ottoman position, providing covering fire for the Auckland Mounted Rifles Regiment attack.
