Military service.

Unusually, Arthurs Army service Records do still exist, though they are badly damaged and only partially legible. He initially joined the Hussars (no. 19787), then transferred to the 1^st Battalion East Yorkshire Regiment (18589) on June 2^nd 1915 and was promoted to sergeant in 4^th Feb 1917.   He was killed on the 4^th October 1917.  This indicates he was probably killed in the late stages of the 3^rd Battle of Ypres (Paschendale).
