From which french documents does the card come from?
It's an ICRC index card (Switzerland, hence the French).
Private Clarence Lee 14543 8th Battalion the Devonshire Regiment was declared presumed killed in action on 25 September 1915, having arrived in France exactly two months earlier. He is commemorated on the Loos Memorial (panels 35 - 37). He was posthumously awarded the 1915 Star, the British War Medal and the Victory Medal.
He was born in Bacup, Lancs c. 1895. Parents John Alfred and Annie Lee of 51 Knowlwood Road, Todmorden.
I think he was almost certainly killed during the first day's fighting at the
Battle of Loos in which the British used chlorine gas, but due to the weather conditions, the gas had more effect of the British troops than on the Germans. The 8th Devonshires lost 619 casualties during the first day. They had virtually no experience of trench warfare and all their officers were inexperienced.
