Russo-Finnish War... also called WINTER WAR (Nov. 30, 1939-March 12, 1940), war waged by the Soviet Union against Finland at the beginning of World War II, following the conclusion of the German-Soviet Nonaggression Pact (Aug. 23, 1939). After Finland had refused to grant the Soviets a naval base and other concessions in the fall of 1939, Soviet troops totaling about one million men attacked Finland on several fronts. The heavily outnumbered Finns put up a skillful and effective defense that winter, and the Red Army made little progress. In February 1940, however, the Soviets used massive artillery bombardments to breach the Mannerheim Line (the Finns' southern defensive barrier stretching across the Karelian Isthmus), after which they streamed northward across the isthmus to the Finnish city of Viipuri (Vyborg). Unable to secure help from Britain and France, the exhausted Finns made peace on Soviet terms on March 12, 1940, agreeing to the cession of western Karelia and to the construction of a Soviet naval base on the Hanko Peninsula.

Armed Conflict Events Database

Armed Conflict Events Data (ACED) is an research project providing independent information about known wars, international disputes, civil wars, rebellions, coups, revolutions, genocides and other violent conflicts. ACED has been online since December 2000. Various partial revisions and modifications have been implemented since then, however, the limitations of the this format hamper further development. During 2005, the decision was made to radically restructure the available conflict information into a database. The new Armed Conflict Events Database (ACEDb) will substantially increase the utility of available conflict data for students of military history. As well, it will offer expanded opportunities to add and edit records of conflict. Existing research material will be maintained in its present form but no revisions are planned. More news about the development of ACEDb may be found at News About the Armed Conflict Events Database. Feedback is welcome.
