Does anyone know if Neuchâtel was created solely for Berthier, and whether it existed as a "country" in the 1814 Campaign for France? It is nestled between France and the Swiss Confederation on my 1811 map, but my post abdication 1814 map doesn't show it any longer. I'm making some maps to accompany Weil and need to know whether it would be proper to show this area's borders.

Thanks in advance.
