At the beginning of July 33 Division moved south to take part in the Somme Offensive. After detraining near Amiens the division marched up through Fricourt and Montauban. It was assigned a role in the Battle of Bazentin Ridge on 15 July, when 100th Bde attacked into High Wood and 98th Bde with a machine gun company was concentrated on the edge of Bazentin le Petit. The attack was a costly failure, and 98th Bde was drawn into the bitter fighting that continued until 20 July.
