Think about that for a moment.

The references are from national archives working on Colossian, you know.

Unlike Enigma’s rotor encryption, Lorenz generated a key stream that was mathematically more complex, making hand analysis impossible after a few days.

4:03
To beat it, engineers at Bletchley built Colossus in nineteen forty-four, a pioneering programmable digital computer using vacuum tubes that could sift through megabytes of traffic in minutes, turning the cryptic German high command messages into readable plans for the Allied front.
speaker_2UNKNOWN
4:21
Before the bombes were fully operational, Dilly Knox pioneered what is now called traffic analysis, recognizing patterns such as message lengths, call signs, and encryption routines that could hint at a message’s destination or importance without knowing the plain text.
speaker_2UNKNOWN
4:39
These early methods allowed codebreakers to focus their brute force attempts on the most likely keys, dramatically reducing the time required to read Enigma traffic.

And for D-Day, Ultra helped planners avoid German radar hotspots and locate Luftwaffe units that might be scrambling over the English Channel, thereby reducing casualties on the first day of Normandy.

6:43
By 1945, Bletchley Park was processing up to 7,000 messages a day across multiple huts, a volume that would require a small army of cryptanalysts if attempted by hand.
speaker_2UNKNOWN
6:55
Every single message went through three stages: collection at the Y stations, relay into Bletchley's huts for preliminary traffic analysis, and finally decryption on bombs or Colossus.

Human operators still played an essential role, manually feeding in rotor settings, inspecting the output for errors, and verifying the plausibility of a decrypted text against known German protocols.
Tom BonnerGUEST
59:05
My gut feeling is we've passed that point.
Tom BonnerGUEST
59:10
The work that the guys did on the Enigma machine and Colossus and some of the early electronic computers, I don't think we'll ever see anything quite like that again.
Tom BonnerGUEST
59:25
When the first step of your task is invent the electronic computer...
Tom BonnerGUEST
59:31
You know, it's very, very difficult.

In 1943, a post office engineer called Tommy Flowers built a code-breaking machine out of 1,500 thermionic valves, partly out of his own pocket.
speaker_1NARRATOR
0:49
Within a year, Colossus, the world's first programmable electronic computer, was cracking Nazi high command ciphers at Bletchley Park.
speaker_1NARRATOR
0:58
Britain had invented the data center in a large shed and chock full of hot electronics that quietly helped us win the war.
speaker_1NARRATOR
1:05
Alongside the Town and Country Planning Act and the squandering of the Marshall Plan money, Britain shot itself in the foot in this regard after the war.
speaker_1NARRATOR
1:14
We destroyed Colossus in a colossal act of self-harm.
speaker_1NARRATOR
1:18
The machines were broken up, the blueprints burned and Tommy Flowers was sworn to silence for 30 years.
speaker_1NARRATOR
1:24
We are at it again.
speaker_1NARRATOR
2:34
In Britain, we can force £100 million to be spent on a bat tunnel.

It took two hundred and sixty-five years for his dream to become a physical reality during World War II at Bletchley Park.
speaker_1HOST
52:19
Faced with the impossible task of cracking German Enigma codes, allied scientists built Colossus, the world's first electronic binary computer.
speaker_1HOST
52:27
It utilized twelve hundred glowing vacuum valves.
speaker_1HOST
52:30
They replaced Leibniz's physical metal balls with electrical currents.
speaker_1HOST
52:33
A valve switched on represented a one.
speaker_1HOST
52:35
A valve switched off represented a zero.
DavidHOST
52:37
Colossus crunched those ones and zeros millions of times a second, cracking the codes and arguably shortening the war by two years.
DavidHOST
52:46
And in doing so, it birthed the modern world.
