He was severely wounded in the shoulder at Messines in October 1914 and invalided home. His younger brother Captain Lord Frederick was wounded at about the same time.
After his recovery Basil went to Ireland as Private Secretary to the Lord Wimborne, Lord Lieutenant where he remained until the Easter Rising.
