According to the Moscow Armistice, signed by Finland and the victorious Allies, mainly the Soviet Union, the Finns were to try those who were responsible for the war and those who had committed war crimes. The Soviet Union allowed Finland to try its own war criminals, unlike other losing countries of the Second World War. The Finnish parliament had to create ex post facto laws for the trials, though in the case of war crimes the country had already signed the Hague IV Convention. In victorious Allied countries war-crime trials were exceptional, but Finland had to arrange full-scale investigations and trials, and report them for the Soviet Union. Criminal charges were filed against 1,381 Finnish POW camp staff members, resulting in 723 convictions and 658 acquittals. They were accused of 42 murders and 342 other homicides. Nine persons were sentenced to life sentences, 17 to imprisonment for 10-15 years, 57 to imprisonment for five to ten years, and 447 to imprisonment varying from one month to five years. Fines or disciplinary corrections were levied out in 124 cases. Although the criminal charges were highly politicized, some war crime charges were filed already during the Continuation War. However, most of them were not processed during wartime.. How many less Finnish staff  were imprisoned for 10-15 than  one month to five years?
