It remains to sketch its phases as, first sullenly, then swiftly, the tide of conflict rolled backward across the miles of country between Sezanne and Rheims. These developments can best be followed day by day. _September 5._--General movement of the German armies across the Marne. The troops of von Kluck crossed at Trilport, Sommery, and La Ferté-sous-Jouarre; those of von Bülow at Château-Thierry; those of von Hausen at Epernay, and Duke Albert's at Chalons. Simultaneously columns of von Kluck's 2nd and 4th Reserve corps began to cross the Ourcq.
