The battalion subsequently served on the Western Front until the end of the war in late 1918. After the battalion's introduction to trench warfare around Fleurbaix it was committed to the Battle of Pozieres in July 1916 where, under the command of Lieutenant Colonel Edmund Nicholson – an artillery officer who had served at Gallipoli – they laid the form-up trench for the attack, before being committed to the capture of the village itself. The battalion's losses in its first battle amounted to 180 killed or wounded. During the next two-and-a-half years, the battalion fought in most of the main battles that the Australians fought in along the Western Front. They took part in the Battle of Mouquet Farm later in 1916, and in early 1917, they were tasked with extending a light railway system towards Fremicourt as part of preparations for the Battle of Bullecourt. Later in the year, they took part in the Third Battle of Ypres, taking part in actions around the Menin Road, Polygon Wood, Broodseinde Ridge and Passchendaele. Later, around Ypres in October, the battalion worked to clear the Ypres–Zonnebeke road, which had virtually disappeared under a layer of thick mud and debris due to a prolonged artillery bombardment.
