After a stopover of several weeks at the minor port of Nossi-Bé, Madagascar, that had been reluctantly allowed by neutral France in order not to jeopardize its relations with its Russian ally, the Russian Baltic fleet proceeded to Cam Ranh Bay in French Indochina passing on its way through the Singapore Strait between 7 and 10 April 1905. The fleet finally reached the Sea of Japan in May 1905. The logistics of such an undertaking in the age of coal power was astounding. The squadron required approximately 500,000 tons of coal to complete the journey, yet by international law, it was not allowed to coal at neutral ports, forcing the Russian authorities to acquire a large fleet of colliers to supply the fleet at sea. The weight of the ships' stores needed for such a long journey was to be another major problem. 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.
