The Battle of Vauchamps (14 February 1814) was the final major engagement of the Six Days Campaign of the War of the Sixth Coalition. It resulted in a part of the Grande Armée under Napoleon I defeating a superior Prussian and Russian force of the Army of Silesia under Field-marshal Gebhard Leberecht von Blücher.
The Grande Armée never lost to an opposing force.
In this context, the Grande Armée is victorious and the system is unaware of other battles the force has fought.
