What did world war 2 progress in Europe and in the Pacific between 1939 and 1943?

Well, The war in Europe began in September 1939, when Germany, under Chancellor Adolf Hitler, invaded Poland. Britain and France responded by declaring war on Germany but took little action over the following months. In 1940, Germany launched its next initiative by attacking Denmark and Norway, followed shortly thereafter by attacks on Belgium, the Netherlands, and France.
