The last setpiece battle for the BEF was the Battle of the Sambre on 4 November, after which it pursued the beaten German forces. 33rd Division took up the lead on its front on the morning of 5 November until it reached the River Sambre itself. 98th Brigade then took up a line between the river and the Forêt de Mormal until after dark, when 1st Middlesex and then 2nd Argylls crossed the river on a floating cork bridge. Next day, while the Royal Engineers built bridges for the artillery, the infantry cleared the villages in front. On 7 November the brigade pushed on again against weak opposition: the guns were across the river by now and their barrages were sufficient to clear rearguards from the villages and woods. 33rd Division was relieved that night. The Armistice with Germany was signed before it went back into the line.
