Battle of the River Plate

The Admiral Graf Spee Leaving Montevideo


<i>Admiral Graf Spee</i> Leaving
Thousands gather along the shoreline to watch as the Admiral Graf Spee departs Montevideo. They believed they were about to witness a great naval battle.

Since December 13 the British Admiralty has been sending ships speeding to Montevideo. Only the heavy cruiser Cumberland has arrived so far. Local British diplomats try to have the Graf Spee held for a few more days until stronger forces arrive and at the same time contrive to give the impression that heavy units, including the battlecruiser Renown, are already in position. Langsdorff, an extremely humane man, therefore decides to scuttle his ship rather than fight a hopeless battle. Admiral Graf Spee is sunk outside the port with an audience of thousands lining the waterfront. 1,039 officers and men are interred in Buenos Aires. On December 20 Langsdorff kills himself.
