During the night of 5/6 August, infantry in the 155th (South Scottish) Brigade and 157th (Highland Light Infantry) Brigade were at Abu Hamra, the 127th (Manchester) Brigade (42nd Division) at Hod el Enna, the 125th (Lancashire Fusiliers) Brigade (42nd Division) on its left in touch with the 156th (Scottish Rifles) Brigade, (52nd Division) which had its left on Redoubt No. 21. The next morning, infantry in the 42nd Division was ordered to advance eastwards at 04:00 and occupy a line from Bir el Mamluk to Bir Katia, while the 52nd (Lowland) Division was to advance from Abu Hamra and prolong the infantry line of the 42nd Division to the north-east. Although they carried out their orders during their two-day march from Pelusium Station to Katia, infantry in the 127th (Manchester) Brigade lost 800 men, victims to thirst and the sun; other infantry brigades suffered similarly. It became clear that the infantry could not go on, and they ceased to be employed in the advance. Indeed, it was necessary for the Bikanir Camel Corps and Yeomanry detachments, as well as the medical services, to search the desert for those who had been left behind.
