The Battle of Flirey (French: 1re Bataille de Flirey) was a First World War battle fought between the 19th of September and 11th of October 1914. It resulted in a German Army victory against the French Army.

As a result, recognising that it is easier to defend the heights alongside the Meuse River (as opposed to the plain between the Moselle and Meuse rivers), a German attack was planned to seize these heights, and so deny access to the Woevre Plain to the Allies. In addition, this would isolate the fortified city of Verdun and reduce the ability of the French to attack German territory.
