After the defeat of Poland, a period known as the Phony War ensued during the winter of 1939–1940, which saw only limited military land operation on the Western Front.[42] All of this changed on May 10, 1940, when the Germans launched a massive attack on the Low Countries (Belgium, the Netherlands, and Luxembourg), most probably to surmount the Maginot Line of defenses on the Franco-German border.[43] This witnessed the incredible fall of Eben Emael, a Belgian fort considered impregnable and guarded by 600 Belgians, to a force of only 88 German paratroopers. The worst of this was that King Leopold III of Belgium surrendered to the Germans on May 28 without warning his allies, exposing the entire flank of the Allied forces to German panzer groups.[44] Following the conquest of the Low Countries, Hitler occupied Denmark and Norway, beginning on April 9, 1940. Norway was strategically important because of its sea routes which supplied crucial Swedish ore to the Nazi war machine. Norway held on for a few crucial weeks, but Denmark surrendered after only four days.[45][46] Sweden was the only Scandinavian country to successfully maintain its neutrality throughout the war, with occasional breaches of neutrality in favor of both Germany and the Western Allies.[47]
