28th HAG resumed CB fire and bombarding strongpoints. The final capture of Guillemont came on 3 September after 95th Siege Bty and other heavy artillery had spent the preceding days shelling the southern end of the village and trenches nearby. The troublesome Falfemont Farm strongpoint was taken early on 5 September. The batteries immediately began preparation for the next planned operation, the Battle of Flers–Courcelette on 15 September, even though no suitable positions could be found to move the guns forward and shorten the range. XIV Corps attacked at 06.20 with Guards and 56th (1/1st London) Divisions after the heavy artillery had maintained a continuous bombardment throughout the night of 14/15 September. Despite heavy casualties, the Guards reached their first and second objectives, but could not get on to the third. The 56th, tasked with forming a defensive flank, was mostly successful, but the Quadrilateral strongpoint held out against them.
