He married the following year, and was awarded the Distinguished Service Order (DSO) in July 1917.

He ended the war in 1918 as officer commanding the 1st Battalion, Somerset Light Infantry, serving in France as part of the British Expeditionary Force (BEF).

His battalion was continuously in touch with the enemy and under heavy shell and machine-gun fire, and its grit and determination reflect the spirit of its commanding officer.

[1] By now believed to be too old for field command, he relinquished command of the 55th Division to Major-General William Morgan, became GOC Northern Ireland District in 1941 and served in the War Office as President of the War Office Regular Commissions Board from 1943.
