Why germany invaded poland

To teach Chamberlain a lesson. Chamberlain's guarantee of Poland on 31 March infuriated Hitler - 'I'll cook them a stew they'll choke on' - was his reaction. To prevent an anti-German alliance. The Nazi-Soviet Pact.

Hitler merely mocked Roosevelt, but he was worried about Stalin. Only Stalin - and the Russian army - could have stopped Hitler taking over Poland at this point. But the failure of the Anglo-Soviet negotiations and the Nazi-Soviet Pact of 23 August not only freed up Hitler to attack Poland, it included a secret agreement to divide Poland up between them.

In the end, Hitler invaded Poland because he had agreed to do so with Stalin. Note : Poland's mobilisation? I have had an email from an historian who questioned the statement in point 7 above that Poland's partial mobilization in broke the provisions of the non-aggression pact.

The historian defended the Polish action in this way: "This was an unofficial, partial and unpublished mobilization, involving 4 infantry divisions and 1 cavalry brigade.

The bombing of Pearl Harbour, which brought the United States into the war on the side of the Allies, had a huge impact on the final outcome of the war. Stalingrad was one of the largest and most brutal battles of the Second World War. Here, German troops run through a trench in the north of Stalingrad during battle. This pamphlet was published in July It circulated the details of a meeting of German resistance in , shortly after the end of the Battle of Stalingrad.

The pamphlet helps to evidence the small but growing discontent from some groups against the Nazis in Germany by this stage in the war. However, this discontent and resistance was typically from small, uncoordinated, groups rather than a united national movement.

Following the invasion of the Soviet Union in , fighting on the eastern front was continuous. The Germans, who had been close to capturing the capital of Moscow in late , were pushed back over miles to west to the town of Rzhev.

This attack was problematic for German morale but, by February , German troops had reorganised. They counterattacked and destroyed several Soviet divisions. This counterattack was soon met with further counterattacks from the Soviets and then the Germans. On the 23 August , the Germans launched an offensive to seize the city of Stalingrad in south-west Russia. The battle was one of the largest and most brutal in history.

It was also one of the only battles of the Second World War to feature hand-to-hand combat. The Germans first attempted to bomb Stalingrad into submission.

The city was reduced to rubble with air attacks by the Luftwaffe. German tanks followed the planes, reaching the outskirts of the city quickly. The German troops entered Stalingrad on the 12 September , advanced quickly and occupied two thirds of the city by the 30 September.

Their rapid advance once again fooled them into thinking that the battle would be quick. The Soviets put up a strong resistance.

Having experienced losses against the Germans almost continuously for the previous year, the Soviet Army saw Stalingrad as an ideological and moral battle as well as a tactical one. In addition to continuous air bombing, fighting in the rubble of the city was characterised by hand-to-hand combat with daggers and bayonets, as each side ambushed the other under the cover of darkness.

By November , Marshal Georgy Zhukov , the Soviet general, had gathered over a million men with several tank armies. Zhukov encircled Axis troops in the north-west of the city. On 19 November , the Russians overwhelmed Romanian armies who were supporting the Germans in the north west of the city. The Germans reacted slowly, and quickly became encircled. Despite General Paulus repeatedly requesting permission to surrender or retreat from Hitler, this was denied.

The , German soldiers that were surrounded by the Soviet Army quickly ran out of ammunition and food in the midst of the Russian winter.

Of the 91, German troops that surrendered, just eventually returned to Germany. Most died from illness, starvation or exhaustion. It was a series of four offensives carried out by Allied troops in central Italy who was a key ally of Germany in an attempt to breakthrough the Winter Line and occupy Rome. Monte Cassino was the mountain above the town of Cassino where the Germans had installed several defences in preparation for the Allied invasion.

An Abbey sat on top of the mountain. One of the primary routes to Rome ran through the town of Cassino at the bottom of the mountain. Other routes to Rome had become impassable due to flooding and the difficult terrain made worse by the winter weather. However, due to the German defences above, passing along the Monte Cassino route was impossible without first defeating the German troops on the mountain.

Allied troops landed in southern Italy in September , but only had limited progress due to the harsh winter and Axis defences. The first attack at Monte Cassino started on 17 January as British Empire, American and French troops fought uphill against the strategic German defences. The German defences were extremely well integrated into the mountainside, and, following large losses, the Allies pulled back on 11 February.

The Allies suspected that the Germans were using the Abbey which was situated at the top of a large hill and protected as neutral territory under the Concordat of as a military observation point. In response, the Allies bombed the Abbey, starting the second offensive of the battle, on 15 February Following the bombing, German troops used the ruins of the Abbey as a fortress and observation post.

The third attack was launched from the north on 15 March. After a large bombing campaign, Allied troops advanced through the town of Cassino. The defences were tough and both sides experienced heavy losses. The German parachute divisions held on to the Abbey.

The Allies fell back, and planned Operation Diadem — the fourth and final battle. The battle involved attacks on four fronts, and took two months to get all the troops in place. The attack started on the evening of 11 May By 17 May, the Polish corps broke through the German defences.

On 4 June , the Allies captured Rome, the capital of Italy. Despite this success, the Battle had come at a cost. There were over 55, casualties for the Allied troops in comparison to 20, German casualties. By the summer of , the Allies had enough coordinated strength to consider an invasion of France. This invasion became known as D-Day.

On the evening of 5 June , under the cover of nightfall, British, French, American and Canadian troops started to cross the English Channel, landing in Normandy. These troops were supported by paratroopers who were dropped behind enemy lines. The next morning, on 6 June , the attack began. With a huge concentration of troops defending the eastern front in the Soviet Union and the decoy measures implemented, resistance from the Germans was initially weaker than expected. Despite this, the Allied troops experienced over 10, losses on the first day.

Despite these losses, the Allied troops made small but significant progress. By 7 June , the Allies had managed to capture the naval port of Cherbourg. This acquisition allowed Allied troops to flood in to France, fighting their way slowly across France, pushing back the German troops. The Germans had, by this point, received reinforcements, but they were overwhelmed by the sheer number of Allied troops. Fought between 22 June and 19 August, the attack resulted in huge casualties for German troops and destroyed their front line on the Eastern Front.

This pushed the remaining German troops back into Poland. They were being defeated and pushed back towards Germany, slowly, by both fronts. Following D-Day and the Invasion of Normandy, the Germans were fighting a defensive war on two fronts. At this stage in the war, the Germans did not have the resources to sustain this.

They were quickly pushed back in France, and retreated into Germany. By March , the Allied troops had crossed the River Rhine. On the Eastern Front, following the Battle of Stalingrad in and , the German Army had been pushed into retreat.

By 17 January , Soviet troops had liberated Warsaw, the capital of Poland. On 27 January the Soviets liberated the Auschwitz Camp complex, which included Auschwitz-Birkenau, the largest Nazi extermination camp. On 16 April , the Soviet troops started the offensive to capture Berlin, the German capital. Led by Marshal Zhukov, who had successfully commanded the Battle of Stalingrad, Soviet troops encircled Berlin, and started their advance inward. On 30 April , Hitler took his own life in his bunker underneath the Reich chancellery.

On 2 May, Berlin was surrendered to the Allies. On 7 May , the German army commanders surrendered all forces to the Allies. This surrender ended the war in Europe. However, the World War was not yet over, and continued in Pacific against the Japanese.

On 6 and 9 August , two atomic bombs were dropped over the Japanese cities of Hiroshima and Nagasaki, instantly killing over , people. Germany had four key fatal weaknesses in the Second World War. These were: the lack of productivity of its war economy, the weak supply lines, the start of a war on two fronts, and the lack of strong leadership. However, they did so on very slow, overextended, supply lines. These supply lines hindered the German advance, and eventually led to a huge lack of supplies on the front line.

This, alongside key Soviet advances, contributed to the German retreat. Throughout the war, Germany became desperately short of fuel, coal and food. It was not until Albert Speer became Minister of Armaments and War Production in that Germany started moving towards a total mobilisation of the economy for war, although this was still with mixed success.

In mid, the economy peaked. For Nazi Germany, in retreat with a defensive war being fought on two fronts, this was too late. Following the Allies D-Day offensive and the simultaneous Soviet offensive Operation Bagration, Germany was fighting a defensive war on the eastern front and on the western front. This meant that the German troops were split, and neither side could have the full weight of the army.

As a result of this, the German troops were pushed back into Germany. In addition to the above, in the closing stages of the war there was a lack of strong leadership in Nazi Germany. German forces broke through Polish defenses along the border and quickly advanced on Warsaw , the Polish capital. Hundreds of thousands of refugees, both Jewish and non-Jewish, fled the German advance hoping the Polish army could halt the German advance.

But, after heavy shelling and bombing, Warsaw surrendered to the Germans within a month of the German attack. Soviet forces quickly annexed most of eastern Poland, while western Poland remained under German occupation until Britain and France, standing by their guarantee of Poland's border, declared war on Germany on September 3, After the defeat of Polish forces, German authorities began enforcing their racial policies in the occupied territories.
