Australian Nos. 1 and 111 Squadrons, which attacked the Tul Keram aerodrome with aerial bombing. This attack was repeated the following morning and evening after German planes bombed the Julis aerodrome and hit No. 113 Squadron's orderly room. The Yeomanry Mounted Division was relieved by the 74th (Yeomanry) Division; two brigades of infantry were substituted for four brigades of cavalry resulting in a sixfold increase in the number of rifles.
