Hi, Hailstone!
About French toponymy. I know it's not easy for English speaking people to pronounce some of our common names,
so when it comes to place names ... [:D]
I nevertheless think that this almost certainly corresponds to "Le-Pont-de-Mons"
(see, Please, WW2 era aerial view) not far from Pont-à-Mousson, department of Meurthe-et-Moselle (Lorraine).
Le-Pont-de-Mons is located east of the Moselle river, halfway between Nancy (to the south) and Metz (to the north).
This locality is very close to the Forêt de Facq.
The essential source for locating, naming (places and actors) and dating events is U.S. ARMY in World War II at:
https://history.army.mil/html/bookshelv ... saww2.html
... within the section devoted to The European Theater of Operations ; The Lorraine Campaign by Colonel Hugh M. Cole,
Center of Military History, US Army, Washington, D.C., 1993.
Sam, for your scenario, an essential reference on river crossing warfare analysis remains too:
DOUBLER, Michael D .; Closing with the Enemy - How GIs fought the War in Europe, 1944-1945; University Press of Kansas, 1994;
Chapter Six "In Spite of Hell and High Water"; the narration is about the efforts of the Patton army to cross this river.
That's All, Folks! [:)]
