A German liner disguised her funnels to look exactly like her British rival — then ran straight into the real ship and lost the world's first liner-vs-liner sea…
In August 1914, both the German liner Cap Trafalgar and the British Cunard liner Carmania were requisitioned and converted into armed merchant cruisers almost overnight — fast, comfortable ocean liners hastily fitted with naval guns and sent to hunt each other's shipping.
Cap Trafalgar's crew went further: they altered her funnels and profile to make her look exactly like Carmania, hoping to slip past Allied patrols disguised as a British ship. It was a disguise that would come back to haunt her.
On September 13, 1914, Cap Trafalgar anchored at remote Trindade Island off Brazil to refuel from German colliers at a secret rendezvous point. Carmania, commanded by Captain Noel Grant, had been sent to that same stretch of ocean specifically to flush out German raiders using the island as a hideout.
The two ships spotted each other on September 14 and maneuvered several miles out to sea for room to fight — a battle later called the world's first engagement between former ocean liners. Carmania fired first but missed; Cap Trafalgar landed the opening hit.
Nearly two hours of point-blank shelling followed. Carmania was struck 79 times, her bridge destroyed and hull holed below the waterline, forcing her crew to steer from aft as fires spread across the ship — yet she stayed afloat.
Cap Trafalgar was less fortunate: a shell tore into her below the waterline, and she began listing badly, lowering lifeboats as she rolled onto her side and sank. Around 279 of her crew were pulled from the water by the German colliers standing by, but 51 died in the fighting or the sinking, including her captain.
Survivors were carried to Buenos Aires and interned for the rest of the war on Argentina's Martín García Island; most weren't repatriated to Germany until 1919. Carmania, burning and listing but still afloat, limped to Pernambuco, Brazil the next day, having lost nine of her crew.
Carmania was repaired at Gibraltar and went on to serve for years afterward — coastal patrols, the Gallipoli campaign in 1916, and troop transport duty — before returning to civilian passenger service in 1919. The ship she'd disguised herself as beat her, and outlived her by decades.
