Overview

In 1940, the German military executed a rapid and shocking invasion of France, known as Blitzkrieg or 'Lightning War.' This tactic focused on breaking through weak points in enemy lines with speed and precision, causing chaos among the Allies. Despite being outnumbered, Germany's innovative approach resulted in quick victories that seemed impossible weeks prior.

The concept of Blitzkrieg was born out of necessity, as Germany's post-WWI restrictions forced them to find new ways of warfare. The experience gained during the Spanish Civil War allowed Germany to perfect these strategies. Key elements such as speed, efficient communication, and exploiting enemy indecision were critical in their initial successes.

However, as World War II progressed, the limitations of Blitzkrieg became apparent. The Allies began to learn from their initial mistakes, and the war shifted to a battle of production, with the Allies gradually overpowering Germany through sheer numbers and resources. Despite late attempts to revive Blitzkrieg, the strategy could not prevent Germany's eventual defeat.

Chapters

• 00:00 - 00:30: Dunkirk 1940 - The Beginning of Blitzkrieg The chapter titled 'Dunkirk 1940 - The Beginning of Blitzkrieg' recounts the dire situation of the British Army during the evacuation from France. The German Luftwaffe dominates the skies, adding to the chaos as hundreds of thousands of men attempt to flee. In just two weeks, following Germany's invasion of France, the Allies' plans had collapsed, leaving evacuation as the only option for survival. The Germans had showcased their blitzkrieg tactics by advancing over a hundred and twenty miles in just five days, marking a significant event in WWII history.
• 00:30 - 01:00: The Concept of Blitzkrieg The chapter titled 'The Concept of Blitzkrieg' introduces the term 'Blitzkrieg' or 'Lightning War,' which became known in the British press during World War II. It explores the strategic principle of Blitzkrieg, which emphasizes achieving victory without engaging in extensive prolonged battles. This approach was notably successful, as highlighted by John Delaney from the Imperial War Museums.
• 01:00 - 02:00: Origins and Necessity of Blitzkrieg The chapter "Origins and Necessity of Blitzkrieg" explores the tactical strategy known as Blitzkrieg, which focuses on identifying and breaking through weak points in enemy lines to cause disruption, rather than direct battlefield destruction. Despite having fewer numbers, this strategy allowed Germany to achieve rapid and unexpected victories. The chapter traces the origins of Blitzkrieg back to the First World War, highlighting how these ideas developed over time to become a key military tactic.
• 02:00 - 03:00: Training and Preparation for Blitzkrieg The concept of Blitzkrieg originated during World War I when all sides sought to break the trench warfare deadlock. For Germany, reestablishing fast-moving warfare was crucial due to the restrictions imposed by the Versailles Treaty, which limited their army to just 100,000 men spread across ten divisions, a stark contrast to France's eighty-five divisions. This necessitated the development of new military strategies.
• 03:00 - 04:00: Key Elements of Successful Blitzkrieg The chapter titled 'Key Elements of Successful Blitzkrieg' explores the necessity behind Germany's innovation in warfare during World War II. Facing a shortage of manpower, they could not revert to traditional First World War tactics. Blitzkrieg, therefore, emerged as a strategic necessity, prompting Germany to adapt new training methods and tactics. The chapter also discusses Germany's involvement in the Spanish Civil War in the mid-1930s, where they engaged actively to gain practical combat experience by sending a legion to support Franco, thereby learning to apply new strategies in real warfare conditions.
• 04:00 - 05:00: German Strategy and Allied Weakness The chapter discusses the early development of the German military strategy leading up to World War II, focusing on how the German army trained effectively even under restrictions. Despite not being allowed to use real military equipment, they used substitutes like cardboard versions of Panzer tanks. The training emphasized rapid progression in rank, ensuring all non-commissioned officers were trained as officers and all junior officers as staff officers. This groundwork enabled Germany, under Hitler's leadership starting in 1933, to quickly expand its military into a professional, mobile army capable of executing Blitzkrieg tactics.
• 05:00 - 06:00: Case Study: The Invasion of France The chapter titled 'Case Study: The Invasion of France' explores the strategy of Blitzkrieg used by Germany during their military campaign. The transcript delves into the necessity of movement to maintain the momentum of attack, emphasizing speed and the importance of always searching for weaknesses in the enemy's defense line. It highlights that a relatively small portion of the German army was mechanized, yet it played a crucial role in executing the Blitzkrieg strategy.
• 06:00 - 07:30: Limitations and the Fall of Blitzkrieg The chapter discusses the limitations that led to the downfall of the Blitzkrieg strategy. Despite Germany being outnumbered, their strategy initially succeeded due to concentrating forces at the point of attack and effectively coordinating with the Luftwaffe for air support. A notable aspect was the speed of communications and decision-making, which was crucial in executing swift military maneuvers.
• 07:30 - 08:00: Final Thoughts on Blitzkrieg's Role in WWII The chapter discusses the strategic importance of identifying weak points in the Allied lines during World War II, emphasizing the application of maximum mechanized force to break through and reach rear areas. It highlights the flexibility required in such attacks and the autonomy given to German junior commanders to make significant decisions on the battlefield. For example, if an assigned attack path seemed heavily defended, they had the authority to change direction to avoid becoming bogged down. This tactical flexibility was crucial for executing successful blitzkrieg operations.

• 00:00 - 00:30 Dunkirk 1940, the British Army is in ruins. Hundreds of thousands of men scramble to escape from France, as the Luftwaffe swirls overhead. It is chaos. Just two weeks after Germany had launched their invasion of France the writing was on the wall, evacuation the only chance of survival. The Germans had advanced with terrifying speed covering over a hundred and twenty miles in just five days. Te Allies plans had unraveled before
• 00:30 - 01:00 them at the hands of a numerically smaller enemy. Suddenly a new word appeared in the British press: Blitzkrieg - Lightning War. So what is Blitzkrieg? And why was it so successful? The main principle of Blitzkrieg is to win by not fighting. That's John Delaney, head of the Second World War team at Imperial War Museums. Now what he said might sound impossible, but in practice it was very effective.
• 01:00 - 01:30 You identify the weak point in the enemy's line, break through, and cause disruption in the enemy's rear areas. So you defeat them by dislocation, not destruction on the battlefield. Despite their inferior numbers Blitzkrieg made it possible for Germany to rapidly defeat its foes and achieve victories that were inconceivable just weeks before, but to find out why we have to go all the way back to the First World War and the genesis of Blitzkrieg. The ideas
• 01:30 - 02:00 behind Blitzkrieg are generated in the First World War when all the sides are looking for ways to break the trench deadlock. The idea of reestablishing fast-moving warfare is of real importance to Germany because the Versailles Treaty, the treaty that comes into force at the end of the war, limits the German army to a maximum size of a hundred thousand men, which means that they have ten divisions which is a tiny amount if you compare that to the French army of the time which is about eighty five divisions strong. So by necessity they have to come up with new
• 02:00 - 02:30 ways of thinking new ways of fighting war, they can't go back to the you traditional First World War because they simply haven't got the men. So blitzkrieg then is born of necessity, Germany has to make do with less. But their small army wasn't the only problem, they also had to find new ways to train. So the the Spanish Civil War which was fought in the mid 1930s, the Germans became heavily involved in and actually sent a legion to fight on Franco's side, to learn how to fight a real war by
• 02:30 - 03:00 fighting a real war. They also trained with cardboard versions of their Panzer tanks because they weren't allowed to have real ones. They trained everybody who was in the German army up to the next rank within the army, so all NCOs were trained as officers, all junior officers are trained as staff officers. Principally what it means for Germany is that when Adolf Hitler comes into power in 1933 there's a small force that can be rapidly expanded into a highly professional mobile army ready to fight a Blitzkrieg war. So with their
• 03:00 - 03:30 preparation now complete Germany was ready to attack, so how did they do it? Well, according to John you need three things to achieve a successful Blitzkrieg. First up, speed of movement. The whole point of blitzkrieg is to keep moving, don't stop, because if you stop you get entangled in a battle of attrition. Keep moving, always look for the weak point in the enemy line. Contrary to popular belief only about 15 percent of the German army was actually mechanised, concentrated at the very tip
• 03:30 - 04:00 of the spear. That mean that even if Germany was outnumbered overall, at the point of attack, she always exceeded her enemies. And then the Luftwaffe, their kit is tailored very specifically to supporting the armed forces on the ground. So the Panzers at the front could call them up and ask pin-point air support from the Luftwaffe's aerial artillery to help them break through the line. And that brings us to number two, the speed of communications and decision making.
• 04:00 - 04:30 The main point is to find this weak point in the Allied line and apply as maximum mechanised pressure you can to that and break through into the rear areas. You need to be able to act flexibly, quickly, and change the axis of your attack extremely quickly so German junior commanders could make very big decisions. Perhaps they've been told to attack down a particular axis towards a hill or something and they could see that that was really well defended. They had the opportunity to say 'I'm not going in that direction we're going to get bogged down over there to our right flank that seems to be much less well
• 04:30 - 05:00 defended we're turning right we're going that direction it'll will break through much quicker'. I mean these these are decisions that are made in minutes whereas French command decisions would take days. And speaking of the Allies the final part is an overconfident enemy. So the Allied armies were geared up to fight the First World War all over again. They've won the last time round so in their mindset why change? You know if it ain't broke don't fix it. So they're geared up to fight a static defensive oriented war, they're not investing in things like
• 05:00 - 05:30 radio communication to enable quick snap decisions to be made near the frontline. Their main a method of communication is to laid telephone lines as it was in the First World War. All you have to do with a telephone line is cut it and then you can't communicate. They were paralyzed, there's just indecision everywhere throughout the command structure of the French and British armies. Put all of that together and it really worked. While the regular German infantry took on the Allies in Belgium and the Netherlands, that armored spear tip found the Allied weak point in the Ardennes
• 05:30 - 06:00 and rushed through it. Encircling their enemy and causing mayhem and destruction at every turn. Once the British had evacuated at Dunkirk, Germany turned south taking in weeks what they had never managed during the whole First World War. By mid-June they were in Paris and by the end of the month the French had signed their humiliating surrender in the same railway carriage as Germany in 1918. But hang on a minute. If blitzkrieg is so powerful then why didn't
• 06:00 - 06:30 Germany keep using it and win the war? So what you what you need to do as the Allies to defeat Blitzkrieg is stay in the war. The Allies, really what they want to do is turn it from this fast-moving Blitzkrieg war into a war of attrition, a war production - literally out producing your enemy. Speed is vital in battle and therefore equally vital is supply. If there's another M in war it is mass. The fighting men on land and in the air need masses of
• 06:30 - 07:00 everything. So this is why Churchill is extraordinarily keen to bring America into the war as soon as possible so he can bring in the American military muscle. Bombs, bombs a multitude of beautiful bombs ready to be delivered just where they hurt most. So if you're fighting a war of production it doesn't matter if you lose the initial battles because you know, in the end, as long as you can hang in there in the end you will out produce the enemy and overpower them just by sheer weight of numbers. But blitzkrieg wasn't quite dead yet, it was successfully used
• 07:00 - 07:30 against the Soviet Union in 1941 who failed to heed to many of the warnings they could have gathered from the Battle of France. But once the Second World War became that war of production and a defensive one for the Germans Blitzkrieg was a far less useful tactic. Despite a late attempt at the Battle of the Bulge in 1944, Blitzkrieg could not save Germany from her ultimate defeat in 1945. So those factors that make Blitzkrieg a necessary strategy and
• 07:30 - 08:00 proved so successful in the early part of the war. Once the Allies have learned what they are and can counter them the Germans have got losing hand, there's nothing else they can do except slowly slowly lose the war.
