Background

In the treaty of Tilsit in 1807 Napoleon and the Russian tzar Alexander I decided that Russia should force Sweden to join the Continental System.

The war

On February 21, 1808 Russian troops crossed the border. At the same time southern Sweden was threatened by an attack from Denmark. The plan of the Swedish army under Johan Adam Cronstedt was to retreat into Ostrobothnia leaving only the strongly fortified Sveaborg behind. The fort surrendered although there was enough ammunition and food to last several months.

The day before Georg Carl von Dbeln had won the legendary Battle of Jutas.
