It was nearly midnight when Dallas commanding 53rd (Welsh) Division, discovered the 54th (East Anglian) Division was moving towards the north of Mansura – had he known of this move at the time, he would not have abandoned all of the captured positions. At 05:00 on 27 March, when Chetwode learned that the 53rd (Welsh) Division had abandoned its entire position, and he ordered them back to Ali Muntar. Dallas ordered the 160th (Welsh Border) Brigade (53rd Division) and 161st (Essex) Brigades (54th Division) to push forward with strong patrols to the positions they had held on the previous evening. Both Green Hill and Ali Muntar were found to be unoccupied and one company of the 1/7th Battalion Essex Regiment, (161st Brigade) reoccupied Ali Muntar, while two companies of the same battalion reoccupied Green Hill. After the 2nd Battalion of the 10th Middlesex Regiment (160th Brigade) had pushed forward patrols beyond Sheluf, the 2nd Battalion of the 4th Royal West Surrey or 4th Royal West Kent Regiment (160th Brigade) was ordered to advance and "gain touch" with the 161st Brigade. However, as the battalion advanced in artillery formation, they could see the 161st Brigade to the northeast "falling back." Meanwhile the 1/1st Battalion, Herefordshire Regiment (158th Brigade, 53rd Division) had also been ordered to reoccupy their brigade's position and was advancing, when they too saw the 161st Brigade withdrawing.
