In researching the Germans and Irish prisoners at Fron Goch, I came across a photo of Police Constable Oliver Cromwell Davies on duty at Fron Goch.
An interesting photo as he appears to be armed and wearing an army ammunition bandolier but obviously the forenames struck a chord given the actions of Oliver Cromwell in Ireland.
A look up on Ancestry.co.uk shows him in the 1911 census as born approx 1892 in Blaenau Ffestiniog in Merionethshire, aged 19, a Police Constable lodging in Barmouth in Merionethshire.
He gave his address as Glyndwr, Frongoch, Bala when he enlisted in the Royal Garrison Artillery on 18th November 1915, number 68104. Age 23years and 5 months. His army service record shows that he was 6ft 1in tall. Sent to Dover for training. His first promotion came on the 30th May 1916 as acting Bombardier, then Bombardier (25/10/1916), Corporal (5/5/1917), acting Sgt (17/11/1917) and then Sgt (14/1/1918). He was discharged to the Class Z army reserve 13th February 1919. He was in the UK until 29th July 1916 and then joined the BEF in France. travelling from Avonmouth to Boulogne to join 124 Siege Battery. Appears to have been wounded 10th August 1918 but no details as to what the wound was.
He was awarded the Belgian Croix de Guerre and the Meritorious Service Medal as well as the British War Medal and Victory Medal.
He appears to have returned to the Police after WW1 and appears as an Inspector in archives at the National Archives.
