The Russian Second Pacific Squadron (the renamed Baltic Fleet) sailed 18,000 nautical miles (33,000 km) to relieve Port Arthur only to hear the demoralizing news that Port Arthur had fallen while it was still at Madagascar. Admiral Rozhestvensky's only hope now was to reach the port of Vladivostok. There were three routes to Vladivostok, with the shortest and most direct passing through Tsushima Strait between Korea and Japan. However, this was also the most dangerous route as it passed between the Japanese home islands and the Japanese naval bases in Korea.
