I saw this movie on the late show in the late 50s – early 60s. French soldier captured by Germans and sent to work on a farm back in Germany. One prisoner takes advantage of the farmers daughter and escapes – daughter may have been sent to a camp. End of war protagonist returns to France where I believe he works in a family bakery. Nagging wife, hates his life and at the end of the movie is going back to the farm in Germany. Think it was dubbed in English but haven’t seen it in 50 years.
“Le passage du Rhin” (1960)
