Here 66th Bde re-assembled and was re-equipped; it was ready for action again on 19 April under VI Corps and spent the next three months exchanging fire with hostile batteries and engaging in HF tasks for VI Corps and 2nd Canadian Division. In late August, with the Allied Hundred Days Offensive under way, 66th Bde was transferred to XVII Corps and moved up to Arras to support Third Army's attacks at the Battles of the Scarpe (26–30 August) and the Drocourt-Quéant Switch Line (2-3 September). On the morning of the D-Q attack, the heavy artillery switched from CB work to a 75-minute concentration on a narrow triangle between the D-Q and Hindenburg Lines, allowing 2/4th South Lancashire Regiment and 1st Royal Munster Fusiliers to advance, each on a single-company front, along the length of both defence lines.
