Certain that Britain and France would do nothing to stop him, Hitler decided to move up his timetable for conquests in the east. On March 15, 1939, Hitler seized what remained of Czechoslovakia, reshaping its pieces into a Bohemian and Moravian protectorate and a nominally independent state of Slovakia. Within a week he annexed from Lithuania the city of Memel and the surrounding countryside, territory lost to Germany in the Memel dispute as a consequence of Versailles. When Britain and France countered these moves by guaranteeing armed assistance to Poland—clearly next on Hitler’s agenda—in the event of German aggression, a furious Hitler ordered his military to prepare an invasion of that country. Poland was critical to Hitler’s long-range strategy for the conquest of Lebensraum in the east; any invasion of the Soviet Union required that Polish territory be available as a staging area. Until the British-French guarantee, he had hoped to enlist Poland, mostly through bombast and threat, as an ally in an attack on the Soviet Union, and he believed Poland could be dealt with summarily after the defeat of the Soviet Union. When Poland refused to play the role he had assigned it, Hitler began looking for allies in his resolution of the Polish problem. In late May 1939 he signed his “Pact of Steel” with Mussolini. Then came the most sensational diplomatic rapprochement of the 20th century. Shortly after signing the pact with Italy, Hitler put out feelers to Soviet leader Joseph Stalin about the possibility of dividing eastern Europe, Poland included, into German and Soviet spheres of influence. These negotiations led to the notorious German-Soviet Nonaggression Pact of August 24, 1939, a pact that secretly sealed Poland’s doom and delayed Hitler’s unbending determination to conquer Lebensraum from the Soviets for almost two years. On September 1, 1939, Hitler launched his invasion of Poland. Two days later Britain and France declared war on Germany. World War II
World War II is appropriately called “Hitler’s war.” Germany was so extraordinarily successful in the first two years that Hitler came close to realizing his aim of establishing hegemony in Europe. But his triumphs were not part of a strategic conception that secured victory in the long run. Nonetheless, the early successes were spectacular. After the defeat of Poland within a month, Hitler turned his attention westward. He believed that it was necessary to defeat Britain and France before he could again turn eastward to the territories that were to become the “living space” for his new empire. The attack on the Western Front began in the spring of 1940. Hitler took Denmark and Norway during the course of a few days in April, and on May 10 he attacked France, along with Luxembourg, Belgium, and The Netherlands. Once again his armies achieved lightning victories; Luxembourg, Belgium, and The Netherlands were overrun in a few days, and France capitulated on June 21. Only the British, now alone, obstructed Hitler’s path to total victory in the west.
Hitler determined that he could take Britain out of the war with air power. German bombers began their attack in August 1940, but the British proved intractable. The vaunted German air force (Luftwaffe) failed to bring Britain to its knees partly because of the strength of the British air force, partly because the German air force was ill-equipped for the task, and partly because the British were able to read German code (see Ultra). Yet Hitler had been so confident of a quick victory that, even before the attack began, he had ordered his military planners to draw up plans for an invasion of the Soviet Union. The date he had set for that invasion was May 15, 1941.
Although the defeat of the Soviet Union was central to Hitler’s strategic objective, during the early months of 1941 he allowed himself to be sidetracked twice into conflicts that delayed his invasion. In both instances he felt obliged to rescue his ally Mussolini from military difficulties. Mussolini had invaded Greece in October 1940, despite the fact that he was already in difficulty in North Africa, where he was unable to cut off Britain’s Mediterranean lifeline in Egypt. In February 1941 Hitler decided to reinforce Mussolini in North Africa by sending an armoured division under the command of General Erwin Rommel. When Mussolini’s invasion of Greece also bogged down, Hitler again decided to send reinforcements. To reach Greece, German troops had to be sent through the Balkan countries, all of them officially neutral. Hitler managed to bully these countries into accepting the passage of German troops, but on March 27 a coup in Yugoslavia overthrew the government, and the new rulers reneged on the agreement. In retaliation Hitler launched what he called Operation Punishment against the Yugoslavs. Yugoslav resistance collapsed quickly, but the effect was to delay for another month the planned invasion of the Soviet Union.
When the invasion of the Soviet Union finally came, on June 22, 1941, it did so with both campaigns against the British, across the English Channel and in the Mediterranean, still incomplete. Hitler was prepared to take the risk that fighting on multiple fronts entailed, because he was convinced that the war against the Soviet Union would be over by the onset of the Russian winter. The spectacular German advances during the first weeks of the invasion seemed proof of Hitler’s calculation. On July 3 his army chief of staff wrote in his war diary that the war had been won. The German Army Group North was approaching Leningrad; Army Group Centre had broken through the Soviet defenses and was rushing toward Moscow; and Army Group South had already captured vast reaches of Ukraine. The prospect of capturing the summer harvest of Ukraine along with the oil fields of the Caucasus led Hitler to transfer troops driving toward Moscow to reinforce those operating in the south.
Hitler’s generals later considered this decision a turning point in the war. The effect was to delay until October the drive toward Moscow. By then an early winter had set in, greatly impeding the German advance and finally bringing it to a halt at the outskirts of Moscow in early December. Then, on December 6, the Soviets, having had time to regroup, launched a massive counteroffensive to relieve their capital city. On the following day the Japanese, nominally Germany’s ally, launched their attack on the U.S. naval base at Pearl Harbor in Hawaii. Although they had not bothered to inform Hitler of their intentions, he was jubilant when he heard the news. “Now it is impossible for us to lose the war,” he told his aides. On December 11 he declared war on the United States.
Though his plans for a quick defeat of the Soviet Union had not been realized, Hitler’s troops at the end of 1941 controlled much of the European territory of the Soviet Union. They stood at the outskirts of Leningrad and Moscow and were in control of all of Ukraine. To prepare for what would now have to be the campaign of 1942, Hitler dismissed a number of generals and assumed himself the strategic and operational command of the armies on the Eastern Front.
At the high point of Hitler’s military successes in the Soviet Union, members of the Nazi leadership were, with Hitler’s understanding, feverishly planning for the new order they intended to impose on the conquered territories. Its realization called both for the removal of obstacles to German settlements and for a solution to the “Jewish problem.” Nazi planners were drafting an elaborate scheme, General Plan East, for the future reorganization of eastern Europe and the western Soviet Union, which called for the elimination of 30 million or more Slavs and the settlement of their territories by German overlords who would control and eventually repopulate the area with Germans. During the fall of 1941 Himmler’s SS expanded and refurbished with gas chambers and crematoriums an old Austrian army barracks near the Polish rail junction at Auschwitz. Here was to continue, with greater efficiency, the Holocaust—the mass murder of Jews that had begun with the June invasion, when SS Einsatzgruppen (“deployment groups”) began rounding up Jews and shooting them by the thousands. The assurance of victory in the east, the heartland of European Jewry, convinced the Nazis that they could implement a “final solution” to the “Jewish problem.” Experts estimate that ultimately some six million Jews were murdered in the death factories of eastern Europe. At least an equal number of non-Jews died of murder and starvation in places like Auschwitz, including two and a half million Soviet prisoners of war and countless others from eastern European nationalities.
