German armed merchant cruiser Thor and British armed merchant cruiser HMS Carnarvon Castle exchange 6-inch shells 300 miles south of Rio de Janeiro, Brazil. HMS Carnarvon Castle was hit 27 times (4 killed, 32 wounded) while Thor was able to disengage unharmed. HMS Carnarvon Castle would soon receive temporary repairs at Montevideo, Uruguay, using steel plates salvaged from the scuttled German pocket battleship Graf Spee.
