 Arriving there on 22 March 1916, the battalion moved to the Armentières area for familiarisation of trench warfare procedures on the Western Front, a completely different style of warfare to that encountered on Gallipoli.In July 1916, as part of the 2nd Division's relief of the 1st Division, the battalion arrived at Pozières, where it took part in the Battle of Pozières.In November 1916, following a period of respite in a quieter sector in Belgium, the 19th Battalion involved in an attack on a trench system known as "the Maze" near Flers, suffered devastating losses in winter conditions that were described as the "worst ever encountered by the AIF".
