On the night of the 25/26th May the setting out of the work was safely accomplished by the Royal Engineers under cover of a screen of scouts, and the following night a working party of 3000 men got to work on the digging, a line of outposts being established for their protection within 200 yards of the German line. The Battalion responsible for W--the right or southern--sector of the new line was the 1/4th Londons, the work being under the control of Major Duncan-Teape, while the L.R.B. undertook the work in Y sector. The night luckily passed quietly, and all ranks working with a will the new trench, shown on map as W 47, W 48, W 49 and W 50, was opened and sunk to a depth sufficient to provide cover. When the Battalion, therefore, took over W sector on the night of the 28th May, the new front line was becoming fit to occupy and had, moreover, reached the anticipated stage in which, the Bosche being alive to what had been done, it was becoming a favourite target for his shells and trench mortar bombs of all calibres. From this time onwards, in fact until the battle, the Divisional sector and in particular the new trenches were daily harassed by the enemy's fire, and constant repair work on the part of our trench garrisons was called for in addition to the continuance of new construction. The front line of W sector was taken up by A Company (A. R. Moore) on the right with B Company (S. Elliott) on the left, supports to both front line companies being found by D Company (Giles), while C Company (Long) was in reserve at Hébuterne. Battalion Headquarters occupied dugouts beneath a roller flour mill in Hébuterne. The move forward from Bayencourt for this relief being made in daylight was carried out across country along tracks, platoons moving separately at 300 yards distance.
