During the afternoon, A and C Squadrons set out towards Daba but halted when night fell. A Squadron approached Mungar Wahla on 5 July but withdrew to Qaret el Yidma after heavy artillery fire. A and B Squadrons patrolled the 4th New Zealand Infantry Brigade front on 6 July. The next day, the division again attempted to drive toward the coast, after an all-clear report. B Squadron screened the 4th and 5th New Zealand Infantry Brigades before being halted by Axis fire and A and C Squadrons were ordered into the line to reconnoitre. Axis tanks attacking C Squadron during the afternoon were repulsed by the 4th New Zealand Infantry Brigade anti-tank guns. Div Cav, the rearguard for the 4th and 5th New Zealand Infantry Brigade retreat, reached Deir el Munassib on the morning of 8 July and received 15 Stuarts. A Squadron patrolled the front of the 22nd Battalion during the afternoon, returning to Deir el Munassib at night. The regiment screened the front on 9–10 July, covering the 5th New Zealand Infantry Brigade night retreat. A and C Squadrons supported a costly, abortive 15 July attack on Ruweisat Ridge and the regiment retreated as the division dug in at the boxes. Two troops were dispatched to join the 18th Battalion on 22 July, encountering an Axis pocket and losing a troop commander. The regiment was incorporated into the New Zealand Divisional box; A and C Squadrons dug in, and B Squadron patrolled south. On 17 and 18 August, A and C Squadrons were relieved by the Buffs and Royal West Kents and moved out. The regiment fought in the Battle of Alam el Halfa, during an attempted German thrust towards the Nile Delta. On 31 August, the regiment was alerted to the coming attack. B Squadron blocked a German advance through the box minefield, retreating after it was flanked, and two troops from A Squadron drove off eight Italian Fiat M13/40 tanks. Later in the morning ten Axis tanks with two 88 mm guns attacked from the Deir el Muhafid and were repulsed by the 26th Battery artillery. The regiment patrolled the northern flank on 3 September and became the mobile reserve during the New Zealand Division attack on the retreating Axis line. It was to follow the 132nd Infantry Brigade and advance to Deir Alinda, to destroy Axis motorized transport, but the brigade was stopped and the regiment withdrew to the box.
