Good evening (French time...),
And thanks a lot to both of you, first for answering me.
Here is what I know about the 371st Infantry (please, don't ask me where it comes from, I don't have a clue...):

- ACTIVITIES OF 369th, 371st, AND 372nd REGTS OF INFANTRY SUBSEQUENT TO THEIR WITHDRAWAL FROM THE MEUSE-ARGONNE OPERATION

369th Inf. Oct 7, etc...

371st and 372nd Inf. Oct 7, the 371st Inf and 372nd Inf, part of the Fr 157th Div, assemble near Beauséjour Farm, north of Minaucourt, and, Oct 11 - 12, move via Valmy and Ste-Menehould to the vicinity of Corcieux. Oct 13 - Nov 11, these regiments, together with the Fr 333rd Inf, occupy the Anould Sector (Alsace) which lies between Weiss Creek and Fave Creek and extends from Tête-des-Faux, through Le Bonhomme, Tête-du-Violu, and Wisembach, to Frapelle; the 371st Inf enters a Bonhomme sub-sector, and the 372nd Inf enters Subsector B, near Wisembach. Nov 17, the regiments move to the Bruyères Area, and on Dec 20, when the Fr 157th Div is disbanded, they revert to GHQ, AEF.

It is clear that the 371st and 372nd Infantry got involved in the Vosges. I'll be eagerly waiting for anything new and thank you in advance. If I can help, as I live in that area, please feel free to ask me and let me know.

Best regards from the Vosges
Eric
