writing on card of WWI soldier missing presumed dead

[issi]

Hi, this card (sorry, not sure of what it is, my notes say "war card") is of Clarence Lee, missing presumed dead at the battle of Loos. What I can't make out is what the handwriting on the card says. I assume it's french. I've posted this here as opposed to the handwriting section because it might be something they usually put in such cases. Any help very welcome.

That is a card from the RedCross P.O.W. Site

The card next to his has a similar, but not the same notation
I think the fact the stamp is Negatif Envoys, means they haven't been able to find any trace of either man after they disappeared at Loos on 25 Sept 1916, and presumably the note (which has another date in November on it) confirms they still haven't found any trace.

Thank you mckha489, nice to know what the source was - I think I came across it via another site that didn't clearly explain what it was.
