was not achieved because of the depth of the Axis minefields. At 22:00, the four infantry divisions of XXX Corps began to move. The objective was to establish a bridgehead before dawn at the imaginary line in the desert where the strongest enemy defences were situated, on the far side of the second mine belt. Once the infantry reached the first minefields, the mine sweepers, including Reconnaissance Corps troops and sappers, moved in to create a passage for the armoured divisions of X Corps. Progress was slower than planned but at 02:00, the first of the 500 tanks crawled forward. By 04:00, the lead tanks were in the minefields, where they stirred up so much dust that there was no visibility at all, traffic jams developed and tanks bogged down. Only about half of the infantry attained their objectives and none of the tanks broke through. The 1st South African Division, on the left flank of XXX Corps, attacked on a two-brigade front to secure the southern end of Miteirya Ridge, with the 2nd South African Infantry Brigade on the right and the 3rd South African Infantry Brigade on the left. The 1st South African Infantry Brigade was deployed further south to create an anti-tank screen for the protection of the left flank of the attack. By 08:00 on 24 October, Miteirya Ridge was secured after a night of heavy fighting and a high number of casualties. The 7th Armoured Division (with a Free French Brigade under command) from XIII Corps (Lieutenant-General Brian Horrocks) made a secondary attack to the south. The main attack aimed to achieve a breakthrough, engage and pin down the 21st Panzer Division and the "Ariete" Division around Jebel Kalakh, while the Free French on the far left were to secure Qaret el Himeimat and the el Taqa plateau. The right flank of the attack was to be protected by 44th Infantry Division with the 131st Infantry Brigade. The attack met determined resistance, mainly from the 185th Infantry Division "Folgore", part of the Ramcke Parachute Brigade and . The minefields were deeper than anticipated and clearing paths through them was impeded by Axis defensive fire. By dawn on 24 October, paths still had not been cleared through the second minefield to release the 22nd and 4th Light Armoured Brigades into the open to make their planned turn north into the rear of enemy positions west of
