The Battle of Guise, launched on August 29, was an attempt by the Fifth Army to capture Guise, they succeeded, but later withdrew on August 30. This delayed the German Second Army's invasion of France, but also hurt Lanrezac's already damaged reputation. The First Battle of the Marne was fought between September 6 and September 12. It started when retreating French forces (the Fifth and Sixth armies), stopped south of the Marne River. Victory seemed close, the First German Army was given orders to surround Paris, unaware the French government had already fled to Bordeaux. The First Battle of the Marne was a French victory, but was a bloody one: the French suffered 250,000 casualties, of which 80,000 died, with similar numbers believed for the Germans, and over 12,700 for the British. The German retreat after the First Battle of the Marne halted at the Aisne River, and the Allies soon caught up, starting the First Battle of the Aisne on September 12. It lasted until September 28, it was indecisive, partially due to machine guns beating back infantry sent to capture enemy positions. In the Battle of Le Cateau, fought on August 26–27, the French Sixth Army prevented the British from being outflanked. The first major Allied attack against German forces since the incarnation of trench warfare on the Western Front, the First Battle of Champagne, lasting from December 20, 1914, until March 17, 1915; it was a German victory, due in part to their machine gun battalions and the well-entrenched German forces.
