After six weeks training in the Campagne region, the 22nd Battalion along with the infantry of I Anzac Corps began to move forward in preparation for their entry into the Third Ypres offensive, with the AIF 2nd Division (photograph right) to Reninghelst and the 1st Division the following day to Ouderdom. During the moonlit nights and during the day the German air force harassed the troops in their camps or on the move by bombing or machine-gun attacks. At no time within the experience of the Australian infantry were the German airmen so active behind the lines. At night searchlights would pick out their prey before the anti-aircraft batteries would try and shower them with shrapnel.
