On the 8th Division front, the two attacking brigades started well, advancing behind an "admirable" barrage and reached the Hanebeek, where hand bridges were used to cross and continue the advance up Anzac Spur, to the green line objectives on the ridge beyond. Difficulties began on the left flank, where troops from 16th (Irish) Division had not kept up with the 8th Division. After reaching the vicinity of Potsdam Redoubt a little later, the 16th (Irish) Division was held up for the rest of the day. The check to the Irish left German machine-gunners north of the railway free to enfilade the area of 8th Division to the south. On the right flank, the same thing happened to the 56th (1/1st London) Division, which was stopped by fire from German strongpoints and pillboxes in their area and from German artillery concentrated to the south-east. After a long fight, the 8th Division captured Iron Cross, Anzac and Zonnebeke redoubts on the rise beyond the Hanebeek, then sent parties over the ridge.
