[otis68]

Good afternoon.I'm from Russia. I apologize for my English.So as write on this forum write through an automatic the interpreter. As I know 21 January 1944 for clock until full environment from Konigsberg is gone the latest echelon ("special Train Koch" as writes in their memoirs Otto Lasch). And there is information that these were sapper or engineering units. And allegedly with this composition there was an armored train. I am interested in the Numbers of all construction parts that performed any work on the territory of Eastern Prussia. Especially the activity of the Todt organization in the production of underground works. Are there any examples in other countries?
