In July 1945, the Dutch submarine O-19 ran hard aground on Ladd Reef in the South China Sea deep in enemy waters. The Gato class submarine USS Cod was sent to rescue the Dutch sub. After two days of attempting to free the stricken sub, the Dutch crew of 56 was taken aboard the USS Cod and the the O-19 was destroyed with torpedoes and fire from the Cod‘s deck guns to prevent it from falling into Japanese hands.
Yesterday in Cleveland, Ohio, the USS Cod‘s deck guns were fired again to commemorate the anniversary of the only international submarine-to-submarine rescue in history.
