A few months later, on 6 January 1810, the Russian government mediated the Treaty of Paris between Sweden and France. Russia would create the Grand Duchy of Finland from the territory obtained from Sweden, and would attach the areas gained from Sweden in the 18th century (so-called Old Finland) to the new Grand Duchy in 1812. The Grand Duchy of Finland was to retain the Gustavian constitution of 1772 with only slight modifications until 1919. Almost all Finnish soldiers in Sweden (most of them in the Umeå area) were repatriated after the war. Analysis Sufficient stocks of supplies had not been prepared for the Swedish army, since King Gustaf IV Adolf thought it might be taken as provocative by the Russians. Furthermore, Swedish strategy relied on the outdated plans for Finland which took into account neither the advances in weaponry, mobility of the armed forces or the greatly improved road networks of Finland. Most of the fortifications in Finland had not been completed and those that were completed had mostly fallen into neglect and disrepair. Even the strongest of the Swedish fortresses, Sveaborg, still had several of its planned fortifications missing, most notably all the land side fortifications designed to protect against a besieging enemy. In 1808 a British expeditionary force under John Moore arrived in Sweden, but after months of idleness departed for the beginning of what became known as the Spanish War of Independence (in Britain, the Peninsular War). Had the king accepted the landing of 10,000 British troops in Skåne, where the expeditionary force had been authorized to disembark, it would have enabled the Swedes to release at least 10,000 trained soldiers for the Finnish War. As it happened, the bulk of the Swedish army, including the best units, were kept out of the Finnish War by the king, who reserved them for his plans for conquering either Sjælland or Norway. Swedish landings were invariably made with poorly equipped and trained forces, often with troops who had very low morale. Landings were further complicated by the Swedish Navy's failure to tightly block the coastal sea route past Hangö. Commemoration The 200th anniversary of the war was selected as the main motif for a high value commemorative coin, the €100 200th Anniversary of Finnish War commemorative coin, minted by Finland in 2008. The motif on the coin is the passage of Finland from Sweden to Russia. The same
