High Quality Content by WIKIPEDIA articles! The Weapons Cache Case is a Finnish criminal case of the late 1940s. It concerned a secret military operation following the Continuation War, where a large number of Finnish Army weapons and equipment was hidden away around the country. Following the Moscow Armistice, two officers in Finnish Military HQ, Colonel Valo Nihtilä and Lieutenant Colonel Usko Haahti, started planning countermeasures against a possible Soviet occupation of the country. They came up with the idea of decentralized storing of light infantry weapons, so that in case of occupation, an immediate guerilla war could be launched. During the demobilization, an organization responsible for hiding the equipment was created and war material was given for safekeeping. A total of 5000-10000 people participated in the operation. It was planned that they would hide material for 8000 men, but the participants worked so eagerly that it is supposed they hid material for 35000 soldiers.
