As time passes, these memorable days stand out more and more gloriously. The study in detail of this stupendous event will continue for centuries hence, but its main lines, which we have been at pains to trace, already stand out clearly. They recall all the old French traditions. The clearness of the plan, the suppleness of manœuvre, the bold use of the reserves, remind one of the Napoleonic era. The enthusiasm which galvanized soldiers and chiefs alike dates back to the Revolution. And going back into the remote past, it was the remembrance of the arresting on the soil of Gaul of the great barbarian invasions which inspired the Victory of the Marne. [Illustration: MARSHAL JOFFRE] TOURIST SECTION For the greater convenience of tourists, we have divided our guide to the Marne Battlefields into the following sub-divisions, which correspond to the three main sectors of the battle: 1, =THE OURCQ=.--Visit to =Chantilly=, =Senlis=, and =Meaux=. 2, =THE MARSHES OF SAINT-GOND=.--Visit to =Coulommiers=, =Provins=, and =Sézanne=. 3, =THE REVIGNY-PASS=.--Visit to =Châlons-sur-Marne=, =Vitry-le-François=, and =Bar-le-Duc=.
