I am trying to find an enlistment date of a ww1 soldier. He joined The Duke Of Edingburghs regiment which was Wiltshire rgt 6th battalion. He wasPvt 36898 F.C. or Frederick Charles Leach born 7th November 1898 brampford speke devon. There are no service records for him. I have his medal card but the joining date is not on it. I am stumped and so are a few others.Any help would be appreciated. Thank you.
