Initiating the world to Nazi Germany's "blitzkrieg" strategy, what country did Germany invade to launch WWII in Europe?

On September 1, 1939, Germany invaded Poland by land and air. Adolf wanted to regain lost territory and, in doing so, initiated WWII. This first run at another country revealed Hitler's "blitzkrieg" strategy, which involved demolishing all communication, transportation, and munition by bombing the life out of territory, before sending in a large number of troops to pick the rest off.
