Below is a copy of an email I received about this canal.
My name is Jean-Christophe VALANCE. Im writting from France and Im passionate about the US Lorrain campaign (09/1944-03/1945). Im living about 32 miles north west from Parroy and 15 miles south east from the german border.
Im very happy to give you informations about the photo concerning "Parroys bridge" figuring into your web site.
In fact the bridge is crossing the canal connecting the Rhine and Marne river (Rhine-Marne canal).
In your photo the canal is empty because all the lock were destroyed by the german forces, the goal was to inundate fields.
I join to my mail a photo taken in the same angle as yours,
houses at the rear side is the village of Parroy. Its easy the recognize
the right flat. You can also recognize the church, in 1944 the "bell tower"
was destroyed.
