context_page_description: The naval Battle off Ulsan, also known as the Battle of the Japanese Sea or Battle of the Korean Strait, took place on 14 August 1904 between cruiser squadrons of the Imperial Russian Navy and the Imperial Japanese Navy during the Russo-Japanese War, four days after the Battle of the Yellow Sea.
context_section_description: A telegram from the First Pacific Squadron at Port Arthur reached Vladivostok on the afternoon of 11 August 1904, stating that Admiral Wilgelm Vitgeft had decided to attempt to break through the Japanese blockade, and therefore Vice Admiral Jessen was ordered to sortie the Vladivostok Cruiser Squadron to assist. However, as late as 5 August 1904, a telegram had been received from Vitgeft stating his intention to perish with Port Arthur, so the Vladivostok cruisers took time to get ready for action. Owing to the delay in sailing, there was little hope of being able to assist the First Pacific Squadron at the critical passage of the Tsushima Straits; however on the assumption that Vitgeft would be successful, the two squadrons planned to rendezvous in the Sea of Japan.
  The warships of the Vladivostok Cruiser Squadron formed in a line abreast at intervals of 4 nautical miles (7.4 km) and headed southward at 14 knots (26 km/h), in hourly expectation of sighting the Port Arthur Squadron. However, the Port Arthur Squadron had not been sighted by the following morning. As the Vladivostok Cruiser Squadron approached Busan, Jessen advised his captains that he had no intention of attempting to pass Tsushima Straits, and ordered the squadron back to Vladivostok.
  The Japanese 2nd Fleet under Admiral Kamimura was made up of four armored cruisers Izumo, Azuma,  Tokiwa, Iwate, and two protected cruisers Naniwa and Takachiho. The Japanese squadron had passed very close to the Russian squadron in the dark of the previous night on opposite courses but neither was aware of the other.
  From  01:30 on 14 August 1904, Kamimura had been heading back from his night patrol area on a course that took him directly to the Russian squadron. When Jessen started his turn back to Vladivostok, he sighted the four Japanese armored cruisers.
  The situation was ideal for the Japanese side. It was dawn on a fine summer day, and the enemy was as far from Vladivostok as it was possible to be in the Sea of Japan, with the Japanese squadron between the Russians and their distant base.
