Due to the pressing need for more soldiers for the Gallipoli campaign, parts of the 2nd Division was sent to Anzac Cove in mid-August 1915, despite the fact that the division was only partially trained. There, they reinforced the 1st Division and the New Zealand and Australian Division. The rest of the division arrived by early September. The 2nd Division held a quiet stretch of the original line (as a majority of the fighting was taking place north of ANZAC Cove), and only a part of the division (the 18th Battalion) saw serious fighting during around Hill 60 on 22 August. The 2nd Division was evacuated from the peninsula in December, returning to Egypt, where it completed its training and formation while the 1st Division was split and used to raise two new divisions (the 4th and 5th) as the AIF was expanded prior to its departure to Europe to fight on the Western Front. A pioneer battalion, designated the 2nd Pioneer Battalion, was added to the division at this time.
