Eric: The 371st Infantry Regiment arrived in France on April 23,1918 and was assigned to the French 157th Division, under general Goybet.
They fought for three months in Avocourt, The Verrieres, N.W. of Verdun.
They were then taken out of line and thrown into the great September offensive in the Champagne. They took Cote188, Bussy Ferme, Ardeuil, Monfauxelles and Trieres Ferme near Monthois and captured a number of prisoners, 47 machine guns, 8 trench engines, 3 field pieces, a munition depot, etc. and shot down three German Boche airplanes.
I saw no assignments in the Alsace or Vosages .
Hope this helps.
