On 25 July 1894, the cruisers Yoshino, Naniwa and Akitsushima of the Japanese flying squadron, which had been patrolling off Asan Bay, encountered the Chinese cruiser Tsi-yuan and gunboat Kwang-yi. These vessels had steamed out of Asan to meet the transport Kow-shing, escorted by the Chinese gunboat Tsao-kiang. After an hour-long engagement, the Tsi-yuan escaped while the Kwang-yi grounded on rocks, where its powder-magazine exploded.
