In early July, Schwarzenberg, having received a request from Wellington and Blücher, ordered Wrede to act as the Austrian vanguard and advance on Paris, and by 5 July, the main body of Wrede's IV Corps had reached Châlons.
Juuli alguses käskis Schwarzenberg, olles saanud Wellingtonilt ja Blücherilt kutse, toimida Wredel kui Austria eelvägi ja edeneda Pariisi, ning 5. juuliks jõudis põhiosa Wrede IV korpusest Châlonsi.
