1 · Understand it

Why France fell in six weeks

The German attack of 10 May 1940 concentrated armoured divisions through the Ardennes, crossed the Meuse at Sedan and drove for the Channel, cutting the Allied armies in Belgium off from those in France. It was not won by superior tanks: French armour was in several respects heavier and better gunned. It was won by concentration, by radio, and by an operational method that valued speed of decision over completeness of preparation.

The mechanism is worth stating precisely, because it is what makes the change examinable. German tanks carried radios and command tanks carried transmitters, so an armoured formation could be redirected while it was moving. French armour was distributed among infantry formations and coordinated by written order and dispatch rider. Two armies with comparable equipment were operating on different timescales, and the faster one dictated the battle.

Air power belongs in the same sentence. German aircraft attacked headquarters, road columns and bridges rather than fighting an independent campaign, and the air arm was trained to answer requests from ground commanders. Dispersing an enemy's ability to give orders is the point; the destruction is secondary.

1940: the first defeat

Between July and October 1940 the German air force attempted to gain air superiority over southern England. It failed against an integrated system: radar chain, ground observers, sector control rooms and fighters directed to intercept rather than patrolling in hope. Hugh Dowding's insistence on holding back reserves and on the control network rather than on maximum sorties is the reason the system survived attrition.

From September 1940 the attack shifted to British cities. The Blitz killed roughly 40,000 civilians over eight months and did not produce the collapse of morale or of government that interwar theory had predicted. That is the first hard evidence against Douhet's claim, and every candidate should carry it.

From 1944 the V weapons — the V-1 flying bomb and the V-2 rocket — resumed the attack by other means. The V-2 could not be intercepted at all, which mattered enormously for the future and very little for 1944: it carried about a tonne of explosive and was fired in numbers far too small to affect the war's outcome.

The bomber offensive, and what it did and did not achieve

From 1942 Arthur Harris directed RAF Bomber Command towards area attacks on German cities at night, while the American force flew daylight raids against specific industries. Hamburg in July 1943 produced a firestorm that killed tens of thousands in a few nights; Dresden in February 1945 did the same at a point when the war's outcome was decided.

German war production nevertheless rose until the middle of 1944. The offensive's real effects were different from the ones intended: it forced Germany to keep enormous fighter and anti-aircraft resources at home rather than at the front, it destroyed the German oil supply from 1944, and it wrecked the transport network. The dispute over whether the results justified the cost — around 55,000 Bomber Command aircrew died — is a live argument among historians and is exactly the sort of thing the interpretation question is set on.

2 · Learn it — the notes

The dates that earn marks

10 May – 22 June 1940

The German offensive in the west; France signs an armistice. Why this date: Six weeks against four years in 1914–18, with broadly the same weapons, is the sharpest evidence for doctrinal rather than technological change.

July – October 1940

The Battle of Britain; the German air force fails to gain air superiority. Why this date: The first defeat of the method, and the first evidence that an integrated defence system beats numbers.

July 1943

The bombing of Hamburg produces a firestorm. Why this date: It marks the point at which area bombing achieved its intended destructive effect, which sharpens rather than settles the argument about results.

1944–45

V-1 and V-2 attacks on Britain and Belgium. Why this date: The V-2 is the first ballistic missile used in war and could not be intercepted, so its significance is post-war rather than wartime.

The figures, and how far to trust them

• About 40,000 — Civilian deaths in Britain during the Blitz of 1940–41. (Figures vary between compilations depending on the period counted; the order of magnitude is secure and the exact total is not.)
• About 55,000 — RAF Bomber Command aircrew killed during the war. (Usually given as around 55,500; it is the cost side of the argument about whether the offensive was worth it.)
• Mid-1944 — The point at which German armaments production peaked, despite three years of bombing.

The people to place

• Hugh Dowding — Commander of RAF Fighter Command; built and defended the integrated air-defence system.
• Arthur Harris — Commander-in-Chief of RAF Bomber Command from 1942; directed the area offensive.

How historians disagree

Attributed interpretations, never voiced — the AO4 seam.

• The 'bombing was decisive' reading: The offensive diverted German fighters, guns and manpower to home defence, destroyed the oil supply and broke the transport system, and without it the land campaigns of 1944–45 would have been far costlier. Contested by The reading that measures the offensive against its own stated aim — breaking morale and production — finds production rising until 1944, and asks whether the same resources spent on the Atlantic or on tactical air power would have shortened the war more..

What students say — and what is actually the case

Not this: Germany won in 1940 because it had better tanks.

This: French tanks such as the Char B1 were better armoured and armed than most German ones. The German advantage was concentration, radio and speed of decision.

Not this: The Blitz broke British morale and nearly forced surrender.

This: It killed about 40,000 people and did not produce political collapse. That failure is the evidence that undermines interwar bombing theory.

Two things students merge

Blurred: The Battle of Britain and the Blitz.

The distinction: The Battle of Britain, roughly July to October 1940, was a fight for air superiority against the RAF. The Blitz, from September 1940 into May 1941, was the bombing of cities after that fight had failed. Merging them hides the fact that the second followed from losing the first.

Blurred: Area bombing and precision bombing.

The distinction: RAF Bomber Command attacked cities at night because it could not hit factories at night; the American force attacked named industries by day at heavy cost. Both are the bombing of Germany and they were doing different things for different reasons.

What a Grade 9 answer holds here

A Grade 9 answer treats 1940 as a communications result rather than an engineering one, and then applies the same test to the bomber offensive: the question is never how much was destroyed but what the destruction made impossible. On that measure the offensive's success was the German fighters and anti-aircraft guns that were never at the front, not the cities that burned.

3 · How it is examined

This strand is genuinely set through: Paper 2 Section B (a) (6 marks — “Explain TWO ways in which … was different from ….”); Paper 2 Section B (b) (8 marks — “Explain TWO causes of ….”); Paper 2 Section B (c)(i) or (c)(ii) (16 marks — “How significant was … in …, in the years …? / How far were … responsible for …, in the years …? You may use the following in your answer: • [prompt] • [prompt]. You must also use information of your own.”).

What earns marks: The radio-in-every-tank fact and the production-rose-until-1944 fact. Each converts a general claim into a supported one, and each is exactly the kind of specific the mark scheme calls precise knowledge.

The cap that bites here: On the 8-mark question, one cause is capped at 4 marks and cannot reach Level 3, however good it is.
