I never met Harold Keyser but I did correspond with him in 1986 when I was seeking information about my great-uncle, Jack Nixon. Jack had been attached to the Post Office Rifles when he was killed in action in October 1918 and, sixty-eight years later, I contacted all surviving members of the Post Office Rifles Old Comrades Association to see if there was anyone who remembered him. Not surprisingly, given the passage of time, no-one did.
Writing to me in November 1986 from his home in Alton, Hampshire, Mr Keyser wrote, "I have no recollection of your relation in the Post Office Rifles. I had suffered an operation in a long period of convalescence prior to the dates you give and subsequently found myself transferred to the 17th London Regiment, much to my disgust but perhaps to my advantage."
