How technology changed the course of war in WW2

Blitzkrieg

Blitzkrieg means "lightning war". Blitzkrieg was first used by the Germans in World War Two and was a tactic based on speed and surprise and needed a military force to be based around light tank units supported by planes and infantry (foot soldiers). The tactic was developed in Germany by an army officer called Hans Guderian. He had written a military pamphlet called "Achtung Panzer" which got into the hands of Hitler. As a tactic it was used to devastating effect in the first years of World War Two and resulted in the British and French armies being pushed back in just a few weeks to the beaches of Dunkirk.

A British view on Blitzkrieg

Blitzkrieg was based on speed, co-ordination and motorized movement (tanks and planes). It was designed to hit hard and move on instantly. Gone were the trenches and the stalemates of World War One.  Its aim was to create panic amongst the civilian population. A civil population on the move can be absolute havoc for a defending army trying to get its forces to the war front. Doubt, confusion and rumour were sure to paralyse both the government and the defending military.

"Speed, and still more speed, and always speed was the secret……..and that demanded audacity, more audacity and always audacity."   Major General Fuller

STEP 1:  knowledge of strategic targets and communication command posts (use of aircraft and paratroopers) STEP 2:  aircraft bombing STEP 3:  heavy tanks STEP 4:  motorized infantry STEP 5:  re group and mop up

Once a strategic target had been selected, Stuka dive bombers were sent in to ‘soften’ up the enemy, destroy all rail lines, communication centres and major rail links.

 This was done as the German tanks were approaching and the planes withdrew only at the last minute so that the enemy did not have time to recover their senses when the tanks attacked supported by infantry. 

Most troops were moved by half-track vehicles so there was no real need for roads though these were repaired so that they could be used by the Germans at a later date. Once a target had been taken, the Germans did not stop to celebrate victory; they moved on to the next target. Retreating civilians hindered any work done by the army being attacked. Those civilians fleeing the fighting were also attacked to create further mayhem.

How effective was Blitzkrieg? 

In 1941, a diary kept by an unknown French soldier was found. In it are some interesting comments that help us understand why this tactic was so successful :

"When the dive-bombers come down, they (the French) stood it for two hours and then ran with their hands over their ears." "Sedan fell as a result of a bombardment……….it was a superb example of military surprise." "The pace is too fast……it’s the co-operation between the dive-bombers and the tanks that is winning the war for Germany." "News that the Germans are in Amiens………this is like some ridiculous nightmare."

Why were the armies of Europe caught so badly prepared by this tactic? 

 In Britain and France, the cavalry regiments ruled supreme and they were adamant that the tanks would not get any influence in their armies. The High Commands of both countries were dominated by the old traditional cavalry regiments and their political pull was great. These were the type of officers despised by Hitler and he took to his Panzer officer, Guderian, over the old officers that were in the German Army (the Wehrmacht). 

In 1940, Britain and France still had a World War One mentality. What tanks they had were poor compared to the German Panzers. British and French tactics were outdated and Britain still had the mentality that as an island we were safe as our navy would protect us.Nazi Germany, if it was to fulfill Hitler's wishes, had to have a modern military tactic if it was to conquer Europe and give to Germany the 'living space' that Hitler deemed was necessary for the Third Reich. 

This method of warfare required mass production of fast, effective weapons, communications technology, and supplies.  It required lots of resources to build it all and smart, skilled,  educated people to run it all.  Here, Canada plays a significant role.
