Source-derived summary

SS Cap Trafalgar was a German ocean liner launched in 1913 for Hamburg Süd. In 1914, she was converted for use as an auxiliary cruiser during World War I. She was sunk in action with HMS Carmania, also a converted ocean liner, in a furious action in the South Atlantic on 14 September 1914. It was the world's first battle between former ocean liners.

Early career

The passenger liner SS Cap Trafalgar was built at the AG Vulcan Shipyard on the Elbe River in Hamburg, Germany for the Hamburg-South America Line for their service between Germany and the River Plate (Río de la Plata). She was named after the Spanish Cape Trafalgar, scene of the famous Battle of Trafalgar in 1805. A three-funneled vessel of 613 ft (187 m) length and 72 ft (22 m) beam, she measured 18,710 GRT and could carry nearly 1,600 passengers (400 1st class, 276 2nd class, 913 3rd or steerage class. A triple-screw vessel, her outer propellers were powered by two triple-expansion steam engines with the centre one driven by an exhaust turbine.

When Cap Trafalgar began her maiden voyage on 10 April 1914 from Hamburg for South American ports in Brazil, Argentina and Uruguay, she was the largest vessel traveling on the South American service and among the most luxurious. Her upper decks included a swimming pool and a cafe in a greenhouse while her 1st class halls and stairwells were full of beautiful gold filigree, and her staterooms were furnished in the highest fashion of the period. She was the epitome of pomp, elegance, and Germanic engineering but when war was declared, her brief career among the socialites and wealthy of the world ended abruptly.
