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.
