Before the war, the Soviet Union demanded for the frontier with Finland on the Karelian Isthmus to be moved westward to a point east of Viipuri to the line between Koivisto and Lipola; for existing fortifications on the Karelian Isthmus to be demolished and for the islands of Suursaari, Tytärsaari, and Koivisto in the Gulf of Finland and Rybachy Peninsula to be ceded. In exchange, the Soviet Union proposed to cede Repola and Porajärvi from Eastern Karelia, an area twice as large as the territories that were originally demanded from the Finns. Foreign support Foreign volunteers World opinion largely supported the Finnish cause, and the Soviet aggression was generally deemed unjustified. World War II had not yet directly affected France, the United Kingdom or the United States; the Winter War was practically the only conflict in Europe at that time and thus held major world interest. Several foreign organisations sent material aid, and many countries granted credit and military materiel to Finland. Nazi Germany allowed arms to pass through its territory to Finland, but after a Swedish newspaper made this public, Adolf Hitler initiated a policy of silence towards Finland, as part of improved German–Soviet relations following the signing of the Molotov–Ribbentrop Pact. The largest foreign contingent came from neighboring Sweden, which provided nearly 8,760 volunteers during the war. The Volunteer Corps was formed of predominantly Swedes, as well as 1,010 Danes and 727 Norwegians. They fought on the northern front at Salla during the last days of the war. A Swedish unit of Gloster Gladiator fighters, named "the Flight Regiment 19" also participated. Swedish anti-air batteries with Bofors guns were responsible for air defence in northern Finland and the city of Turku. Volunteers arrived from Hungary, Italy and Estonia. 350 American nationals of Finnish background volunteered, and 210 volunteers of other nationalities arrived in Finland before the war ended. Max Manus, a Norwegian, fought in the Winter War before returning to Norway and later achieved fame as a resistance fighter during the German occupation of Norway. In total, Finland received 12,000 volunteers, 50 of whom died during the war. The British actor Christopher Lee volunteered in the war for two weeks, but did not face combat. White émigrés and Russian prisoners-of-war Finland officially refused overtures from the anti-Soviet Russian All-Military Union (ROVS) for aid. Nevertheless, Mannerheim eventually agreed to establish a small Russian detachment (Russkaya narodnaya armiya, RNA) of
