Ralph, I am learning so much by posting here. Thank you for your time.

If the normal route for my Lyon letter was via Strasbourg, then that was obstructed by the Siege at Belfort The Siege ended two weeks later. The senders of the letter might have been told the only certain route to Berlin was using the Swiss postal system.

Here's another letter which originated in Altkirch, France, 9 December 1870, a non-direct route around the battle area to Mirecourt, France.
Entered the mails in Porrentruy 9 December, transited Basel 10 December [back], also with the oval Schweiz uber Baden on the back. No other routing date stamps. Is my guess that the letter went via Freiburg correct? And where would it have gone from there?



Even as late as July 1871 there was still disruption in postal routes.
Originated 3 July 1871 in Mulhouse, posted basel 5 July, transit Mont Cenis a Macon 6 July (via Geneva), received Reims 7 July. I have no idea of the routing once the letter left the Mont Cenis train.




Any information about routes will be very helpful. Thanks again.
Roger
