 By early June the German forces had cut off the line from the rest of France and the French government was making overtures for an armistice, which was signed on 22 June in Compiègne.As the line was surrounded, the German Army attacked a few ouvrages from the rear, but were unsuccessful in capturing any significant fortifications.The main fortifications of the line were still mostly intact, a number of commanders were prepared to hold out, and the Italian advance had been contained.
