The division returned to the front line on 10 May in the region of Hill 60 and began preparations for the attack. These preparation were observed by the Germans on the higher ground who assaulted the line on 13 May, which was repulsed, this attracted counter raiding by the 70th Brigade on 16 and 20 May. During this time the division's easily observed artillery attracted heavy German counter battery fire with serious casualties resulting. The division was to form the left flank of the advance on a front ~2000 yards wide, with its furthest advance ~1400 yards deep. After the artillery bombardment and the detonation of 19 mines on 7 June, the 69th and 70th brigades (the 69th reinforced with the 11th Northumberland Fusiliers and 12th Durham Light Infantry) advanced over the ridge and down each side of the valley on the southern flank of the Klein-Zillebeke spur, with fresh battalions leap-frogging the others when the second phase line had been reached. The new line was held until the 24th Division relieved them on 13 June.
