Early in May the battalions of the 2nd Brigade moved from the beachhead at Anzac Cove to the British and French lodgement at Cape Helles where on 8 May they were involved in the Second Battle of Krithia, carrying out the first brigade-level attack by Australian infantry against an entrenched enemy force and during which they suffered losses equal to roughly a third of its strength in what was a largely unsuccessful attack. After this the 2nd Brigade returned to Anzac Cove on 16 May. During the August Offensive they took part in the Battle of Lone Pine during the August Offensive. Following this the brigade was involved in largely defensive duties until they were withdrawn as part of the general evacuation of Allied troops from the peninsula in December 1915.
