Only at 1:30pm did 30th Corps HQ realize that the 18th Indian Infantry Brigade was in extreme danger. They were informed by the 1st South African Division of the situation. The armoured cars, however, made an erroneous report that made the brigade position was quiet. This report was made at 2:30pm. Finally, at the last moment, 30th Corps ordered the 22nd Armoured Brigade towards Deir el Shein, where the 18th Indian Infantry Brigade was near collapse. The 22nd Armoured Brigade ran into German armour and had fight. The Germans were from the 15th Panzer Division and were driven back.
Over the same period, the 90th Light Division had gotten in trouble. They had finally been able to disengage from the El Alamein position by 1:30pm. They came under fire from the entire 1st South African Division (all three brigades). They lost their composure and when they had regained it, they had "gone to ground". This is based on the account in Vol.III of the Official History.
