Matilda II Tank: London Bus Engines, Rommel's 88s and the Jungle Hedgehog

SPEAKER_1 (0:00)

So, how does a massive war machine, powered by like two London public transit bus engines, a tank that basically maxed out at the speed of a brisk jog, become the most terrifying weapon on the early battlefields of World War II?

SPEAKER_2 (0:14)

It really is this incredible historical paradox. And well, to understand how that actually happened, we are taking a deep dive into the historical and technical records of the A12 Matilda II Infantry Tank.

SPEAKER_1 (0:26)

Right.

And our mission today is to explore for you, the listener, the entire philosophy behind the creation of this mechanical behemoth. We're going to track its spectacular highs, its crushing lows, and how its bizarre design quirks allowed it to become the only British tank to serve from the very first day of the war all the way to the last.

SPEAKER_2 (0:47)

Which is a crazy achievement when you think about it.

SPEAKER_1 (0:50)

Totally. So setting the stage here, if you want to understand why someone would intentionally build a tank that moves at a walking pace, you really have to look at what the British military was thinking during the 1920s and 30s.

SPEAKER_2 (1:02)

Yeah, and what they were thinking about pretty much constantly was the trauma of the First World War.

SPEAKER_1 (1:06)

Right, the trenches.

SPEAKER_2 (1:07)

Exactly. Military theorists like Major General Percy Hobart and Captain Basil Liddell Hart, they were trying to solve the nightmare of trench warfare, the mud, the endless machine gun fire.

SPEAKER_1 (1:19)

Because nobody wanted a repeat of the Somme.

SPEAKER_2 (1:22)

Exactly. And the British doctrine that emerged from this period made a very specific, somewhat controversial choice. They decided to split their tank development into two completely separate concepts.

They didn't want a jack-of-all-trades vehicle.

SPEAKER_1 (1:36)

I always think of this like a toolkit. They looked at the idea of a multi-tool and said, no, we want a highly specialized hammer and we want a highly specialized scalpel.

SPEAKER_2 (1:45)

That is actually the perfect way to look at it. So the scalpel was the cruiser tank.

These were lightly armored, very fast vehicles designed to punch through enemy lines and cause absolute chaos in the rear.

SPEAKER_1 (1:58)

Kind of functioning like traditional horse cavalry, right?

SPEAKER_2 (2:00)

Yeah, exactly like cavalry. Now, the hammer, on the other hand, was the infantry tank.

These were designed to advance directly alongside foot soldiers. Their only job was to absorb enemy fire, crush barbed wire, and systematically knock out fortified trenches.

SPEAKER_1 (2:16)

Which means, logically, speed isn't just a low priority here. It is intentionally ignored.

SPEAKER_2 (2:22)

Right.

SPEAKER_1 (2:22)

Because if the tank drives faster than the infantry can walk, it leaves the foot soldiers completely unprotected.

SPEAKER_2 (2:27)

Exactly. And that philosophy leads directly to the Matilda series.

So the military first built the Matilda I, which was, I mean, it was tiny. It held only two men and just had a single machine gun.

SPEAKER_1 (2:38)

Not exactly a massive hammer.

SPEAKER_2 (2:40)

No, not at all. So by 1936, they realized they needed a much larger hammer, something with an actual cannon to deal with enemy artillery.

And that specification becomes the A12, the Matilda II.

SPEAKER_1 (2:53)

Okay, so they scale it up.

SPEAKER_2 (2:55)

Oh, they scale it way up. The defining characteristic of this new machine was its protection.

The frontal armor plate was up to 78 millimeters thick.

SPEAKER_1 (3:04)

Let's give that a little bit of comparison for context. What were the German forces working with at that exact same time?

SPEAKER_2 (3:10)

Well, to put 78 millimeters in perspective, contemporary German tanks like the early Panzer III and Panzer IV, they were rolling into battle with maybe 30 to 50 millimeters of frontal armor.

SPEAKER_1 (3:21)

Wow. So the British had designed a tank with nearly double the protection of the best tanks the enemy could field.

SPEAKER_2 (3:27)

Yeah, nearly double. It also featured a cast three-man turret mounting an Ordnance QF two-pounder gun, which at the time was a very capable 40-millimeter anti-tank cannon.

SPEAKER_1 (3:38)

But okay, strapping 78 millimeters of solid steel onto the front of a vehicle in like 70 millimeters on the sides, that creates an immediate physics problem.

SPEAKER_2 (3:46)

No, a massive one.

SPEAKER_1 (3:48)

Right. Because I was looking at the weight specifications and the records, and this thing tipped the scales at 27 tons. In the late 1930s, how do you even move a literal steel fortress when tank engines of that era are terribly underpowered?

SPEAKER_2 (4:02)

It's pretty funny actually. The designers found a highly pragmatic, if totally bizarre solution to that power deficit.

Rather than spending years designing a massive new engine from scratch, they just went straight to the commercial sector.
