While preparations for D-Day reached their final stages the Allies made a fateful decision to campaign vigorously on the Italian front in hopes of drawing off German reserves from France. But German resistance was fierce, and by October autumn rains curtailed Allied attacks, ending their dream of bursting into Austria from the south.

By spring 1944 the Germans had mustered 59 divisions in France and the Low Countries, but only 10 were motorized and almost 30 were in static defense positions. As the Allied buildup in England reached huge proportions, the Germans tried to divine where the blow would come. Hitler and Rommel thought Normandy; the theatre commander, Rundstedt, believed Calais. Their deployments reflected a compromise. Meanwhile, Roosevelt and Marshall chose Eisenhower to command Supreme Headquarters Allied Expeditionary Force (SHAEF), and he managed the preparation of “Overlord,” the cross-Channel invasion, with tact and skill. More than 3,000,000 men crowded into southern English bases and ports, anxiously awaiting a D-Day on which 176,475 soldiers, 20,111 vehicles, 1,500 tanks, and 12,000 planes would move by air and sea across the Channel. Eisenhower described them as being “as tense as a coiled spring.” Elaborate deceptions kept the Germans guessing about the point of attack, and Normandy was chosen in part because it was not the easiest or nearest French beachhead. On June 6, American, British, and Canadian forces went ashore, but seven tense and bloody weeks passed before the Allies broke out of the Norman peninsula. The initial campaign, thanks to Allied courage and matériel and German blunders, removed more divisions from the Wehrmacht’s order of battle than even the great Soviet offensive of June 1944.

As Allied armies raced westward and northward to liberate France, Eisenhower faced the problem of what to do with Paris. He had no desire to interrupt the drive for a difficult urban battle, nor to undertake the chore of feeding 4,000,000 inhabitants. But the Parisian police went on strike on August 19, and de Gaulle secretly ordered French forces to seize the capital. Meanwhile, Hitler had ordered that the landmarks of Paris be blown up before the Germans retreated. But garrison commander Dietrich von Choltitz refused to carry out the order and negotiated a surrender that opened the city to Allied forces on the 25th. Eisenhower gave the honour of leading the parade to de Gaulle and General Jacques-Philippe Leclerc.

Soviet advances in the east

In five months from D-Day the Western Allies liberated France and Belgium and advanced 350 miles. In the midst of the Normandy campaign, on June 22, the Red Army launched its summer offensive. Armoured spearheads chased German remnants to the East Prussian border and the banks of the Vistula by July 31, an advance of 450 miles in five weeks. By October the Baltic coast was cleared of Germans. These massive victories carried the Red Army to the borders of nine states that had been independent before 1939, making possible the sovietization of eastern Europe. The first episode in that process stemmed from an uprising by the Polish Home Army in Warsaw, underground allies of the London Poles. Expecting momentary liberation from across the Vistula, the Home Army rebelled against the German occupation and seized control of the city. But Stalin called it a “reckless venture,” and the Soviets sat idly by while Hitler ordered in SS divisions to crush the resistance and flatten the ancient city. To be sure, the Red Army had just finished a huge advance that stretched its supply lines to the limit. But Stalin shed no tears over the slaughter of the non-Communist Warsaw Poles, who held out bravely for eight weeks, and even hindered U.S. and British planes from supplying Warsaw by denying them landing rights in Soviet territory. On August 22, Stalin simply dismissed the Warsaw Poles as “criminals” and set up his Moscow Poles in Lublin as the acting government of “liberated Poland.” In the north, the Finns sued for peace in early September, accepting their 1940 losses and giving up in addition the Arctic port of Petsamo (Pechenga), and a $300,000,000 indemnity, terms confirmed in the treaty of peace concluded in 1947. The U.S.S.R. allowed the Finns self-rule so long as Helsinki coordinated its foreign policy with that of the U.S.S.R. Latvia, Lithuania, and Estonia, however, were reannexed.

The Soviets unleashed another major offensive in August through Bessarabia, even though the Balkan front was irrelevant to the quick defeat of Germany. King Michael concluded an armistice with Moscow on September 12. Citing the Italian precedent, Molotov brushed aside the Western Allies’ attempts to win a share of influence over Romanian affairs. Bulgaria, which was not at war with the U.S.S.R., tried to establish its neutrality, but the Red Army occupied it anyway and set up a “Fatherland Front” in which Communists were predominant. When Soviet and Romanian troops invaded Hungary in October, Horthy tried to extract his country from the war. But the SS arranged his overthrow, and fighting continued until the fall of Budapest on February 13, 1945. A foolish waste of troops for the Nazis, the battle of Budapest was equally irrational for Stalin unless his true goal was political. Meanwhile, Yugoslav partisans under a local Communist, Josip Broz Tito, captured Belgrade on October 20, 1944, and evicted the Germans.

One by one the states of eastern Europe were falling to Communist forces in circumstances prejudicing their future independence. When Churchill arrived in Moscow on October 9, 1944, he tried to contain the march of Communism into central Europe by making a deal with Stalin on spheres of influence: Romania to be 90 percent Soviet; Greece 90 percent British; Yugoslavia and Hungary 50–50; Bulgaria 75 percent Soviet, 25 British. While apparently a realistic response to Soviet ambitions—and presence—in contrast to Roosevelt’s reliance on vague principles, Churchill’s proposal was in fact rather silly. Stalin was unlikely to grant Western influence in countries under Soviet occupation (like Hungary), while the meaning of such numbers as “75–25” was unfathomable. Poland was not mentioned at all. On the other hand, Churchill did forestall Soviet aid to the Communist partisans in Greece and may have helped to shield the crucial Mediterranean from Soviet influence for years after the war.
