consolidate and allow the 32nd Division to pass through them to a distant objective. As will be seen the programme allotted was, so far as the 46th Division was concerned, carried through according to plan. To the storming Infantry was allotted a few sections of Engineers for purposes as already outlined when describing Engineer preparations, while the remainder of the Divisional Engineers and the Pioneer Battalion followed close in the rear of the assaulting columns, bringing up bridging and road-making material.
