On return from Gallipoli the AIF was reorganised into the & II Anzac Corps in preparation for serving with the BEF in France. The composition of these Corps varied during the war but were made up of Australian, New Zealand and British units.

In November 1917 the two Australian Corps were combined into the I Anzac Corps which was renamed The Australian Corps.
The II Anzac Corps was renamed and became a British and New Zealand unit.
The Corps Mounted Troops became the XXII Corps.
