after u/MammaMcCheese found her grandfather letters she was able to find the city where he was stationned ( Bar-le-Duc ) then the courageous u/happy_otter had the idea to browse old postcards on the internet to find the monument http://imgur.com/3F3IvfR André Thieuret was a writer,and not a very reknowed one... Thanks to all for your help. As you can see even with a better picture it is difficult to read the inscriptions.
