A British Ocean Liner With Eight 6 Inch Guns Fought Two German Battlecruisers — For 14 Minutes

November 1939: A converted P&O ocean liner encountered two German battlecruisers between Iceland and the Faroe Islands. HMS Rawalpindi displaced 16,697 tons, mounted eight World War I-era 6-inch guns, and possessed zero armor. Scharnhorst and Gneisenau displaced 32,000 tons each, carried nine 11-inch guns apiece, and were protected by 14-inch turret armor. The engagement lasted fourteen minutes.

This is the story of Armed Merchant Cruisers—Britain's desperate solution to a cruiser shortage that required 300 vessels but possessed only 77. Converting ocean liners cost £50,000 and took eight weeks. Building proper cruisers cost £2 million and required three years. The mathematics demanded sacrifice. Captain Edward Kennedy commanded a floating target that couldn't win. He fought anyway, because strategic necessity required that German capital ships never operate without consequence.

This video examines the brutal economics of Armed Merchant Cruisers: why Britain converted luxury liners into warships, why those conversions were tactically suicidal but strategically essential, and why Rawalpindi's fourteen-minute battle—accomplishing nothing militarily—forced Germany to abort an entire commerce raiding operation. Sometimes the best weapon isn't one that destroys the enemy. Sometimes it's simply one that exists, forcing the enemy to account for its presence.
