took part in the Anzac landing on 25 April 1915, as part of the second wave. Ten days after the landing, the 2nd Brigade was transferred from Anzac to Cape Helles to help in the attack on the village of Krithia. The attack captured little ground but cost the brigade almost a third of its strength. The Victorian battalions returned to Anzac to help defend the beachhead, and in August the 2nd Brigade fought at the battle of Lone Pine.
