Steaming steadily through the night, Togo, with the main body of the Japanese fleet, had passed to eastward of the scattered Russians, and was about twenty miles south of Ullondo. The distances covered in this battle of Tsu-shima were beyond any that had ever been known in naval war. The running fight during the night had passed over more than 150 miles of sea. At 5.20 a.m. the admiral on board the "Mikasa" received a wireless message from Kataoka's cruisers, reporting that they were sixty miles away to the southward of him, and that they could see several columns of black smoke on the horizon to the eastward. Shortly after Kataoka sent another wireless message--"Four of the enemy's battleships and two cruisers are in sight, steering north-west." Togo at once signalled to his own ships to head off this detachment of the enemy, and sent wireless orders to Kataoka and Uriu to close in on their rear. It was probably the main fighting division left to the Russians, and would soon be surrounded by an overwhelming Japanese force. The ships sighted by the cruisers were those that Admiral Nebogatoff had led through the night, and was trying to take to Vladivostock. He had with him the battleships "Nikolai I" and "Orel," the coast-defence armour-clads "Admiral Apraxin" and "Admiral Senyavin," and the cruisers "Izumrud" and "Svietlana." This last ship was leaking badly and down by the bows. She could not keep up with the others, and at daylight fell far astern and lost sight of them. At 7 a.m. Uriu's division in chase of Nebogatoff came up with her, and the cruisers "Niitaka" and "Otowa" were detached to capture her. The Russian captain, Schein, had held a council with his officers. He had only a hundred shells left in the magazines, and the "Svietlana" was being kept afloat by her steam pumps. Under the regulations he could have honourably surrendered to a superior force, but it was unanimously resolved to fight to the last shot, and then sink with colours flying. The fight lasted an hour. There were heavy losses. The Japanese fire riddled the ship, and first the starboard, then the port engine was disabled. As the hundredth shot rang out from the "Svietlana's" guns, Captain Schein stopped the pumps and opened the sea-cocks, and the ship settled down rapidly in the water. The Japanese cruisers went off to join the fleet as the "Svietlana" disappeared, but an armed Japanese liner, the "America Maru," stood by and picked up about a hundred men. At 10.30 a.m. Nebogatoff was completely surrounded eighteen miles south of the island of Takeshima. The "Izumrud" had used her superior speed to get away to the south-west. The four battered ships that remained with him saw more than twenty enemies appear from all points of the compass, including Togo's battleships and heavy armoured cruisers, all as fit for work as when the first fighting began. They opened fire at long range with their heavy guns.
