In February 1942, the German battleships Scharnhorst and Gneisenau and the heavy cruiser Prinz Eugen sailed from Brest up the English Channel in broad daylight, and the British did not notice until they were nearly at the Strait of Dover. This episode unpacks Operation Cerberus: why the ships were pinned in France under relentless RAF bombing, the dawn torpedo run that earned Kenneth Campbell a posthumous Victoria Cross, and Hitler’s decision to overrule Admiral Raeder and take the shortest, most dangerous route home to guard Norway.

We break down General Wolfgang Martini’s masterstroke of gradually raising radar interference until British operators mistook jamming for winter static, Adolf Galland’s rolling fighter umbrella, and the new-moon, bad-weather, spring-tide timing. Then comes the cascade of British failures: a Hudson’s radar breaking down, cancelled and recalled patrols, Spitfire pilots keeping radio silence, blind coastal guns, Eugene Esmonde’s six Swordfish biplanes shot from the sky, torpedo boats held off by E-boats, and bombers dropping armor-piercing bombs from 700 feet. Finally, magnetic mines struck both battleships, and the episode asks whether the dash was a triumph or the most spectacular retreat in naval history.

• Why Brest made the German raiders a constant target for Bomber Command
• The white-noise radar deception that blinded Britain without triggering alarms
• How siloed British commands attacked one at a time instead of together
• Why armor-piercing bombs need altitude, and why 700 feet made them useless
• The strategic irony: Gneisenau never sailed again, Prinz Eugen was torpedoed, and Scharnhorst sank at North Cape
