I want to know the answer to the following question:
The new plan called for which army to remain in a defensive grouping at the German border?
All the background I'm provided with is that "This plan was discarded in favour of a defensive plan by Generals Charles Frossard and Bartélemy Lebrun, which called for the Army of the Rhine to remain in a defensive posture near the German border and repel any Prussian offensive.". Is that enough to answer the question?
