 In late August, the Australian 2nd Division advanced to the Somme River, and on 29 August, as the 7th Brigade attacked around Biaches, the 28th was assigned the task of capturing the Amiens–Peronne railway bridge.The following day, they forced their way across the river around Peronne, and during the subsequent Battle of Mont St Quentin–Peronne, they joined the 7th Brigade's advance towards Aizecourt-le-Haut.They continued fighting until early October 1918 when they were withdrawn from the line, just after an attack on the Beaureviour Line, around the village of Estrees.
