Salmon War

The conflict zone, around 1796/97, east at the top. An arm of the Rhine separates the island of Schusterinsel in the centre from the mainland. Below it, on the left bank of the Rhine, lies the fortress of Hüningen. On the island and the right bank of the Rhine are its outworks. The forked mouth of the Wiese river and Kleinhüningen are right and above right. The 1738 border with Basle is shown as a red line and divides the Schusterinsel and river. (the width of the map is just under 2 kilometres, its height is just under 1.4 kilometres.)

The Salmon War (German: Lachsfangstreit) of 1736/37 was a political conflict between the confederate Canton of Basle and the Kingdom of France over fishing rights and the location of their state border in the River Rhine.
