As early as in 1812, prior to the Napoleonic invasion of Russia, the Swedish Crown Prince Charles John had entered into an agreement with Tsar Alexander I that Russia would support a Swedish attack on Norway in order to force Denmark-Norway to cede its northern part to Sweden. The Swedish attack against Norway was rejected, however, and Swedish forces were instead directed against France in Central Europe. The Swedish troops were deployed against Napoleon's forces as a result of agreements between Charles John and diplomats from the United Kingdom and Prussia, which indicated that Norway would be ceded to Sweden after France and its allies (which included Denmark-Norway) were defeated.
