As the Scandinavian nations rarely participated in warfare during the 20th century, little has been written about their armed forces. However, they have employed formidable forces in many wars, as this study demonstrates. The volume includes discussion of: prehistoric warriors, Vikings; wars between Denmark and Sweden; the Thirty Years War; the Great Northern War; the Russo-Swedish Wars; the German Confederation reduces Denmark; the dilemma of World War I; the invasion of Scandinavia in 1940; the Russo-Finnish Wars; Sweden mobilizes for four invasion threats; the Scandinavians fight with the Allies and Axis; and postwar Scandinavia armed forces. There are photographs and illustrations of weapons and uniforms.
