It appears that their are some fence posts to the left down the slope upon which the soldier lies. Also of interest, if not in direct reply to your question; what is the mass under his head? It seems to be a bandage. There is what looks like stiff canvas strapping rising up out of the cloth(?) and bending to the right under his canteen. Just under his ear is some kind of container, with whar looks like a portrait on it. Suggestions, experts? Stan
