World War II: Blitzkrieg and the Eastern Front

French and German Plans for the Battle of France 1940 French anticipated the Germans attacking through the north as they did in World War I so they developed the Dye Plan to counter such an attack Built the Maginot Line in the south to protect the border (recalling the trench warfare of WWI)

Maginot Line A line of concrete fortifications, tank obstacles, machine gun posts and other defenses which France constructed along her borders with Germany and Italy The fortifications did not extend through the Ardennes Forest which was considered “impassable”

Surprise in the Ardennes On May 12, 1940 Germany attacked through the weakly held Ardennes region Penetrated Allied defenses and then began to envelop them

Halt Order Hitler halted the German armor German armor had suffered heavy losses and would be needed to conquer the rest of France Luftwaffe called upon to finish the job Luftwaffe unable to destroy the British and French Bases in western Germany were further away from Dunkirk than British planes were from their bases on the British Isles 340,000 Allied troops were evacuated

The Weygand Line Collapses Battle of France: June 4-14, 1940

Italy Joins the Axis On June 10, 1940, Mussolini declared war on Britain and France and four months later invaded Greece Mussolini will end up being a troublesome ally for Hitler

French Surrender and Vichy France On June 16, the French asked for an armistice In July, France was divided into two sections One was ruled directly by the Germans The other was led by the Vichy government that collaborated with German plans including the plunder of French resources and the forceful deportations of tens of thousands of French Jews to concentration camps across Europe

Auftragstaktik German interwar doctrine emphasized: decentralized, mission-oriented orders (Auftragstaktik) speed and exploitation of enemy weaknesses maximized by troop commanders taking the initiative (understand commander’s intent) close integration and cooperation between combat branches (mobile warfare required armor, infantry, and artillery) leadership from the front

Battle of Britain The Germans developed two plans to take Britain Operation Sea Lion, an amphibious landing on the British coast A great air offensive to gain air superiority and destroy the British industrial base “Let us therefore brace ourselves to our duties and so bear ourselves that, if the British Empire and its Commonwealth last for a thousand years, men will still say, ‘This was their finest hour.’” (Winston Churchill)

Hitler had strategic and ideological reasons for invading Russia The Eastern Front Hitler had strategic and ideological reasons for invading Russia Strategically he knew that the Soviet Union and the US were critical to Britain’s willingness to keep fighting He also felt he needed the agricultural and raw material resources of Eastern Russia Ideologically he viewed the Soviet Union as an amalgamation of his greatest enemies, the Jews and the Slavs

Operation Barbarossa Hitler based his plan on the assumption he could destroy the Soviet Union within one year Critical to his success would be to catch and destroy the Soviet Army at the border areas If that did not occur, the Russians could use their vast territory to trade space for time and cause the Germans huge logistical problems

Operation Barbarossa On June 22, 1941, Hitler invaded Russia in Operation Barbarossa The operation encompassed a total troop strength of about 4 million men, making it the biggest single land operation ever Benefiting from initial surprise, by the end of July Hitler had occupied a portion of Russia twice the size of France

Operation Barbarossa: Battle of Moscow With the Germans’ successes in the north and south, Hitler assumed that Stalin’s regime was on the verge of collapse He authorized an advance on Moscow before the onset of winter Already however the Germans were suffering from serious supply shortages By September the supply system was only meeting current tactical consumption needs No supply stores for the winter season were being built

Operation Barbarossa: Battle of Moscow The Germans caught the Russians unprepared and made great advances The Soviet Army seemed on the verge of collapse At this point the weather broke and autumn rains turned the roads to mud The German advance stalled, allowing the Russians to hurry reinforcements from the interior

Operation Barbarossa: Battle of Moscow Despite dropping temperatures and critical supply shortages, the German high command pressed on with the attack The German soldiers were still in summer uniforms and suffered terribly German soldier during the battle of Moscow

Operation Barbarossa: Battle of Moscow Stalin responded to the crisis by rushing his best commander, Georgi Zhukov, to defend Moscow Zhukov waged a delaying defense in front of Moscow; the first time the Soviets took advantage of their ability to trade space for time In the meantime he pulled reinforcements from as far away as Siberia to defend Moscow Zhukov’s plan was to allow the Germans to exhaust themselves and then go on the offensive

Operation Barbarossa: Battle of Moscow By Dec 4 the Germans had clawed their way to Moscow’s outskirts, but they could not continue That night temperatures were -25 degrees Fahrenheit One infantry regiment suffered 300 frostbite casualties On Dec 6 the Soviets counterattacked

Operation Barbarossa : Battle of Moscow Rundstedt, the German commander of Army Group South, ordered a retreat and Hitler fired him Field Marshall Walther von Reichenau replaced Rundstedt and confirmed the withdraw order and then suffered a heart attack Hitler was in the midst of a high command crisis and lost confidence in his generals Field Marshall Walther von Reichenau

Strategic Situation On Dec 7, 1941, Japan attacked the US at Pearl Harbor In spite of his troubles in Russia, Hitler decided to support Japan and also declare war on the US Now the US would join with Britain to adopt a “Europe First” strategy that would destroy Hitler

Operation Barbarossa : Battle of Moscow As the Russians pushed forward, Hitler refused to allow a retreat and relieved or court- martialed generals who did so Hitler named himself commander-in-chief of the army Each military service began to operate increasingly independently and Germany suffered from a lack of an overall strategy

Operation Barbarossa : Battle of Moscow On the Eastern Front the Germans’ stiff resistance and control of crucial roads and supply centers slowly took the punch out of the Russian counterattack The German Army survived but it suffered losses from which it never recovered Both sides licked their wounds and prepared for renewed operations in the spring

Stalingrad As spring 1942 approached, German commanders recommended remaining on the defensive but Hitler believed the Germans must destroy Soviet military potential before the American industrial power could come into play Hitler developed a plan to capture Soviet oil At first Hitler considered Stalingrad of little importance other than the fact that its capture might block the movement of petroleum up the Volga River

Stalingrad On June 28 the Germans launched their summer offensive The Germans made good headway with one advance moving east toward Stalingrad and the Volga River and another moving south into the Caucasus In August Hitler’s erratic attention swung from the Caucasus to Stalingrad

Stalingrad On Aug 24 the Germans attacked Stalingrad’s suburbs and began fighting their way into the city Hitler began shifting forces from the Caucasus to Stalingrad The nature of the urban fighting favored the defenders and the Soviets mounted a stubborn defense Stalingrad began to drain the German army but Hitler would not back off

Stalingrad On Nov 19 the Soviets launched a massive counterattack north of Stalingrad Hitler’s overly centralized and completely out-of-touch command system broke down in the face of the Soviet onslaught The Soviets encircled Stalingrad and Hitler ordered his commanders to stand fast anyway By this point in the war, no one was willing to confront Hitler

Stalingrad German POWs All attempts to breakout or break through failed and on Feb 2 the Germans surrendered Out of 250,000 soldiers trapped in the Stalingrad pocket, approximately 90,000 became prisoners Barely 5,000 survived the war German POWs

Greatest Extent of Axis Control

The Eastern Front Ultimately enormous logistical shortcomings made Barbarossa a failure Germany proved capable of fighting battles very well, but was less capable of fighting a war of prolonged duration In the total four years of fighting on the Eastern Front, an estimated 4 million Axis and 9 million Russians were killed in battle 20 million Soviet civilians were killed as a result of extermination campaigns against Jews, communists and partisans, casual massacres, reprisal killings, diseases, and (sometimes planned) starvation.
