In general terms the Marne is an Allied victory which saved Paris and kept France in the war; it also ensured the failure of the Schlieffen Plan for a quick German victory in the West. However there is less agreement as to the extent of the Allies' success.

Recruitment figures show that between 4 August and 12 September, 478,893 men joined the army. This includes 33,204 volunteers on 3 September which was a wartime record.
