The Battle of the River Plate is an almost documentary like account of the battle of the German pocket battleship Graf Spee with three allied cruisers and what happened to her subsequently. Heading the small mini fleet was Captain Anthony Quayle and the German captain of the Graf Spee was played by Peter Finch.
December of 1939 was the period known as the 'phony war'. Poland had been overrun by the Nazis and the British and French forces were on the continent safely behind the Maginot line or so they thought at the time. What action there was at this time was on the sea with various naval engagements here and there.
The Graf Spee was doing one number on British commerce in the South Atlantic. It sank nine British merchant vessels, but her captain was no Nazi. He observed the rules of war strictly, picked up sailors from the sunken vessels and all reported good treatment at his hands. When he did reach Montevideo he let all the British sailors go. Sad to say this was not something repeated during World War II.
In any event two British and one New Zealand cruiser, the Ajax, the Achilles and the Exeter took on the Graf Spee and fought it to a bloody standstill. The British were lucky to have facilities at the Falkland Islands for repair. But the Graf Spee headed for Montevideo which was neutral territory at the time.
I'm not quite sure why they did not make for the friendlier shores of Buenos Aires on the River Plate. Even though Juan Peron had not taken charge in Argentina, it was still friendlier to the Germans than Uruguay was. Possibly Finch's character Lansdorff knew the history of Uruguay, a country founded as a neutral buffer state between Argentina and Brazil. In any event the Uruguayans operated correctly under the assumption that they would be at war sooner or later with the Germans as indeed were all the Latin American countries except Argentina after Pearl Harbor. The Graf Spee would have made quite the prize indeed.
As German, British, and Uruguayan diplomats tried to negotiate, Finch took action and blew up the Graf Spee in the middle of the River Plate. The Nazi propaganda machine made him a martyr which in fact he was and the British public was given something to cheer about in those beginning days of World War II.
Finch and Quayle give good performances as a pair of gallant adversaries and The Battle Of The River Plate is a fine war film from the United Kingdom in which even the enemy behaved gallantly.
