In the spring of 1940, an emboldened Germany asserted itself as a modern conqueror of nations, successfully invading and occupying six countries in fewer than 100 days. On April 9, 1940, Germany invaded Denmark, which capitulated in a mere six hours. At the same time, Nazi warships and troops were entering Norwegian waters, attacking ships, landing troops, and starting a conflict that would last for two months. On May 10, more than 2 million German troops on land and in the air invaded France, Belgium, Luxembourg, and the Netherlands using blitzkrieg tactics. The smaller countries fell within weeks, but France held on until June 22, when it signed an armistice with Germany. Also during this period, the Soviet Union initiated staged elections in Estonia, Latvia, and Lithuania, forcefully annexing them. By the end of the summer, German forces were digging in, building up, and planning for the Battle of Britain. (This entry is Part 3 of a weekly 20-part retrospective of World War II)
