On 16 September 1597, during the Seven Year War, the Korean admiral Yi Sun-sin achieved a decisive victory in the Battle of Myeongnyang held at the Myeongnyang Strait. With 13 panokseons and about 200 men he defeated the Japanese fleet of 133 warships and 200 support ships. During the lifetime of Yi Sun-sin, the strait was also known as 'Uldolmok,' or 'the Roaring Channel,' most likely due to the powerful tidal forces in the channel, which were especially loud in spring.
