Remember people: the Memorial Museum of the Battle of Normandy in Bayeux where I shot these pictures is ABOVE ALL a MUSEUM.
NOT a cemetery or a memorial to the dead themselves.
Like I wrote in my first comment, everything looked OK in the other places I visited.
Also, remember that foreign soldier's military cemeteries actually BELONG to their respective country (which is why I can claim I went to the United States without physically leaving France) and there is NO WAY their flag can be removed (unless their own country decides).
And remember I wrote about troubling (yeah, very troubling) coincidences for which we would love to hear an explanation.
At this point, there is no reason to blame any official organism in this country for these… troubling empty spaces where we could possibly expect to see a… flag.
