Operation Gold: A Cold War Failure

In the 1950s, the CIA and British intelligence launched a daring Cold War mission…

Operation Gold. The goal? Dig a secret tunnel under East Berlin… To tap into Soviet

phone lines and gather intelligence. The tunnel was over 1,400 feet long, reinforced,

and hidden beneath a fake warehouse. For months, they listened in — undetected.

But there was a problem… The Soviets already knew. A KGB mole inside

British intelligence had exposed the entire plan before the tunnel was even finished.

The Soviets let it run — feeding false info until they staged a dramatic “discovery.”

Operation Gold became a Cold War embarrassment… A tunnel full of secrets — That led nowhere.
