After almost five months’ service in the line—including the battle of Amiens (August 8 - 11, 1918)— Carmen returned to England for officer’s training, prior to receiving a commissioned rank. Initially appointed Acting Sergeant on August 31, Carmen was promoted to the rank of Lieutenant on November 22, 1918. He enrolled with the Khaki University of Canada, London, on February 3, 1919 and proceeded to the Royal Technical College, Glasgow, for completion of a course of study.
Carmen departed England on July 18, 1919 and was formally discharged from military service on July 31, 1919. He subsequently settled at Ottawa, where he commenced employment as a chemist. Arriving in Vancouver, BC in July 1927, Carmen departed for New Zealand shortly afterward. He married Sybil Marion Martin at Auckland, NZ in 1928. The couple’s first son, John Martin, was born the following year. Two more children - a boy and a girl - later joined the family.
The family returned to Vancouver, BC in 1932, but relocated to San Francisco, California in 1941 and moved on to Hawaii in 1949. Carmen Milward Croft passed away at Sydney, Australia in 1955, and was laid to rest in Forestlawn Cemetery, Vancouver, BC.
