On 13 September 1918, the brigade transferred to IX Corps, which had been reconstituted in Fourth Army to take a leading role in the continuing Hundred Days Offensive. IX Corps assigned it to 1st Division for the Battle of Épehy (18 September), the attack on The Quadrilateral and Fresnoy (24 September), the Battle of St Quentin Canal (29 September–2 October) and the Battle of the Beaurevoir Line (3–5 October). It was rested for a while, then went back into the line supporting 1st and 32nd Divisions in the Battle of the Selle (16–20 October). After another short rest, it caught up with 46th (North Midland) Division in time for the Battle of the Sambre (4–8 November), when the division advanced on 7 November to seize the Avesnes road. As 138th (Lincoln &amp; Leicester) Bde advanced up the road, CCXXXI (2nd North Midland) and then CCXCVIII AFA Bdes put down concentrations of fire on the main points of resistance and the Germans began to withdraw.
