Imperial Mounted Division on 27 June 1917, joining the new division at el Maraqeb. On 20 June, the Imperial Mounted Division was redesignated
Australian Mounted Division as the majority of its units were now Australian. • the
8th Mounted Brigade arrived back in Egypt from Salonika on 8 June 1917. The Machine Gun Squadron was formed in Egypt on 14 June. The brigade moved forward and joined the new division on 21 July 1917 at el Fuqari. • the
22nd Mounted Brigade was transferred complete from the
ANZAC Mounted Division on 6 July 1917, joining the new division at el Fuqari. • the CCLXIII (V Lowland)
