During the Allied Hundred Days Offensive, 4th Division fought as part of the Canadian Corps in the Battle of the Scarpe and the Battle of the Drocourt-Quéant Line. It then reverted to the British XXII Corps for the rest of the war. For the Battle of the Canal du Nord, the Division constructed dummy figures made of painted canvas on wooden frames to represent an advance in No Man's Land. While its neighbouring division put in a genuine assault on 27 September, 4th Division fired a barrage and pulled up these figures. Then, that night, the divisional engineers constructed a bridge across the Trinquis and 4th Division established posts across the river. The Battle of the Selle involved another major assault bridging operation, and the pursuit of the defeated Germans entailed much bridging of destroyed culverts and cratered roads left by the enemy.
