The Mysterious British Voyage That Hid the World's Wealth Underwater

In the summer of 1940, with Nazi Germany at the gates and Britain standing alone, a secret operation was quietly launched that most people have never heard of. Hundreds of crates, each weighing 60 kilograms, were loaded onto warships in the dead of night on the River Clyde. No crowds. No announcements. No record that anything unusual was happening at all. Inside those crates was the combined gold reserve of half of Europe. Operation Fish moved the equivalent of fifty billion pounds in today's money across a U-boat infested Atlantic — and the Germans never knew it was happening. Every ship arrived safely. Not a single gram was lost. It remains the largest movement of physical wealth in the history of human civilisation. This is the story they didn't teach you in school.
