The Germans would push on "as fast as he could drive" them from 30 June 1942 on wards

As was almost always the case, Rommel's only play in his book was to use infiltration tactics to try and upset the enemy morale. Rommel's men were in bad shape and were short on supplies. They also did not know when they might receive any more. Rommel issued orders to the German Africa Corps and the 90th Light Division to push into British territory before daylight in the area "between the El Alamein position and Deir el Abyad." Rommel ordered the 90th Light Division to turn towards the sea and cut off the El Alamein Box. The German Africa Corps would turn to the south would hit the rear areas of XIII Corps. The Italian Trento Division would attack El Alamein from the west side. The Italian Brescia Division would move forward behind the German Africa Corps. They also had the Italian XX Corps with the Ariete Armored Division and the Triested Motorized Division. They were ordered to attack the Qattara Box. The attack would be on new territory and would be in the dark, so that there would be no real chance to do any reconnaissance prior to attacking.
The British, following Auchinleck's latest ideas and trying to imitate Rommel's battle groups. The South Africans formed up two columns, leaving only one brigade in the box they had occupied. That meant that there were no units facing east from the box. The 50th Division formed three columns, each with eight field guns. The 10th Indian Division and the 5th Indian Division also created columns.
looking back at 30 June 1942, the British rearguard drove through the El Alamein Box. They were closely followed by the 90th Light Division. The Germans stopped short of the box and opened fire with artillery. German aircraft also started bombing the box. The 90th Light Division needed to prepare for the "big attack" planned for the next morning. Being in such a hurry had left the German staff with a mistaken idea of where the British units were deployed. The XXX Corps was actually in the north, but the Germans expected to see the X Corps there. The facts were that both sides were confused and not prepared. Auchinleck at the army headquarters was out of touch with what the situation was on the ground, so was Rommel. This is based on the account in Vol.III of the Australian Official History.
