The division then reverted to British command for the Allied Hundred Days Offensive, beginning with the Second Battle of Bapaume, when it effectively exploited a pre-dawn attack by 2nd Division on 25 August. 5th Battalion KOYLI was prominent in driving the Germans out of Mory, taking many prisoners. The division then attacked again in the afternoon of 29 August behind a creeping barrage. It continued with the Battle of the Drocourt-Quéant Line (2 September) and then advanced to the Hindenburg Line to participate in the Battle of Havrincourt on 12 September. 187 Brigade attacked on the right of the division, supported by heavy artillery, and within an hour of zero was sending back batches of prisoners. Four officers and 80 men had been captured at a strongpoint by Sergeant Laurence Calvert, MM, of 5th KOYLI, who had rushed the enemy machine gun teams single-handed, bayonetting three and shooting four. Calvert was also awarded the VC.
