After his service ended, he began farming and also was active in the Legion of Frontiersmen, eventually becoming its New Zealand commandant.

Francis Morphet Twisleton, known as Frank, was born on 17 February 1873 in Settle, Yorkshire, England to a farmer and his wife.

In 1911 he became involved with the Legion of Frontiersmen, an organisation which found favour with many veterans of the Boer War like Twisleton.

Twisleton was involved in organising and training of a squadron of horsemen for the Legion's Poverty Bay branch.

A lieutenant, he continued his letter writing habits of the Boer War, regularly describing life in the trenches in correspondence home.

[1] After recovering his health, Twisleton was posted to the New Zealand Pioneer Battalion, which was a mainly Māori unit but with a company drawn from the Otago Mounted Rifles.

In October 1917 he was transferred to the Auckland Mounted Rifles Regiment, which was serving in the Palestine Theatre of Operations and shortly afterwards was promoted to major and given command of a squadron of horsemen.

[2] After Twisleton's death, the Legion of Frontiersmen recognised his services with the Pioneer Axe, its highest award.
