In 1917, Chaytor took over the Australian and New Zealand Mounted Division, and was promoted to temporary major general in April.[4] When taking part in the assault on Rafa he ignored Chetwode's order to withdraw from the attack and took the town's main defensive position. In 1918 Chaytor's Force captured Amman in Jordan and thousands of prisoners.
He married Louisa Jane Collins, daughter of Charles Sweeney Collins, on 17 October 1898. Together they had three children. Son Edward John Clervaux Chaytor (1903–1976) was a Brigadier in the Royal Artillery; daughter Katherine, married Sir Robert Gooch, 11th Baronet.
