The ANZAC Mounted Division was formed in Egypt in March 1916 with four cavalry brigades. Four British Territorial Force horse artillery batteries were assigned to the division to provide artillery support (one per brigade). These were controlled by two Royal Horse Artillery brigade headquarters: III Brigade, RHA (T.F.) and IV Brigade, RHA (T.F.). The ANZAC Mounted Division served with the Desert Column in the Sinai and Palestine Campaign from the Battle of Magdhaba (23 December 1916) through to the Second Battle of Gaza (1719 April 1917).
