Part of his service record has survived. He enlisted in the 4th DCLI on 5 Sept 1914, and was discharged on 28 August 1917 suffering from debility and defective vision. There are several pages of medical reports which are extremely difficult to read, but apparently his eyesight was damaged in an accident in 1912. Another part of the report seems to mention that he went to India but returned on leave in 1916 - hence he would have been able to marry in Redruth - but I can't make out the remainder of the narrative.
He was an accountant in civilian life and he was promoted to Sergeant on 11 September 1914, then further promoted to the acting rank of Colour Sergeant and employed as a company quartermaster sergeant (CQMS) on 9 December 1914, 3 days before going to India. He returned from India on 11 October 1916.
His record is on FindMyPast. His first regimental number was 2154, and in early 1917 this was changed to 200431 in line with the policy of renumbering Territorial Force soldiers. He appears to have only been awarded the British War Medal. He received a pension pay out but his wife did not qualify for extra support as they married after he had been removed from duty. 1 shilling and sixpence was allowed for his child.
