卡爾十三世
The "de facto" Swedish ruler, Crown Prince Charles John, acting on behalf of King Charles XIII of Sweden, rejected the premise of an independent Norway and launched a military campaign on July 2, 1814 with an attack on the Hvaler islands and the city of Fredrikstad. The Swedish army was superior in numbers, better equipped and trained and was led by one of Napoleon's foremost generals, the newly-elected Swedish crown prince, Jean Baptiste Bernadotte.
