Sorry, the url for the map should be as follows

And the airfield was at 'Oiry' not Bisseuil - all the alternative names are a bit confusing and I still haven't quite got my head round it. But it was Oiry which is referred to in one of the AIR40 files dealing with airfields in France in June & July (Bisseuil was yet another alternative name for ATHIS)
