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.
The situation was desperate. Nebogatoff consulted his officers, and all those on board the "Nikolai" agreed that he must surrender. In a memorandum he subsequently wrote he pointed out that, though some ammunition was left, the Japanese were using their superior speed to keep a distance at which he could not reply effectively to their overwhelming fire; neither the shore nor other ships were within reach; most of the boats had been shattered, the rest could not be lowered; even the life-belts had been burned or used to improvise defences in the ships; continued resistance or the act of sinking the ships would only mean the useless sacrifice of some 2000 men. After the ships had been only a short time in action, during which time they received further severe damage, he hauled down his colours. Togo allowed the Russian officers to retain their swords, as a proof of his opinion that they had acted as befitted brave and honourable men.
While the brief action with Nebogatoff's squadron was in progress, the third of the Russian coast-defence battleships, the "Admiral Ushakoff," hove in sight. She turned off to the westward pursued by the armoured cruisers "Iwate" and "Yakumo." They soon overhauled her, and signalled a summons to surrender, adding that Nebogatoff had already done so. The "Ushakoff" replied with her 9-inch guns. The cruisers sank her in an hour, and then rescued some three-fourths of her crew of 400 men.
The "Sissoi Veliki," badly injured in the action of the day before, and torpedoed during the night, was in a sinking condition when the sun rose on 28 May. No ships were in sight, all the boats had been destroyed, and while the pumps were still kept going the crew was set to work to construct rafts. While this was being done with very scanty materials, the "Vladimir Monomach" hove in sight, accompanied by the destroyer "Iromki." In reply to a signal for help, the "Monomach" answered that she could do nothing, as she was herself expecting to sink soon. The "Iromki" offered to take a few men, but the captain of the "Sissoi" generously refused to deprive the "Monomach" of her help. The two ships then steamed away. An hour later the "Sissoi" was just settling down in the water, when three Japanese armed merchant steamers appeared and took off her crew. At half-past ten the "Sissoi" heeled over to starboard and sank.
Soon after she lost sight of the "Sissoi," the "Monomach" came upon the armoured cruiser "Admiral Nakhimoff," which also signalled that she was in a sinking condition. Presently there was smoke on the horizon, and then the armed steamer "Sadu Maru" and the Japanese destroyer "Shiranui" appeared. In such conditions the enemy proved a friend. The crews of the two unfortunate ships were transferred to the "Sadu," which stood by till, about ten o'clock, both the "Nakhimoff" and the "Monomach" went to the bottom.
The "Navarin" was comparatively little injured in the battle, but was torpedoed during the night. Leaking badly, she struggled northward at a slow rate till two in the afternoon of the 28th, when she was found and attacked by a Japanese destroyer flotilla. She still made a fight with her lighter guns, and was hit by two torpedoes. The crew were all at their battle stations when she began suddenly to sink. The order, "All hands on deck," came too late, and very few lives were saved.
The armoured cruiser "Dimitri Donskoi," last survivor of Rojdestvensky's fourteen battleships and armoured cruisers, escaped the torpedo attacks in the night, and eluded pursuit all through the morning of the 28th. At 4 p.m., when she was near the island of Ullondo, she sighted some Japanese ships in the distance, Uriu's cruiser division and some destroyers. They closed slowly on her, and it was not till six o'clock that she was attacked by the cruisers "Niitaka" and "Otowa," and three destroyers. The "Donskoi" made a gallant fight for two hours, beating off the torpedo-boats, losing sixty killed and twice as many wounded, and finally disengaging herself in the darkness about eight o'clock. The water-line armour was intact, but one boiler was penetrated and ammunition was nearly exhausted. In the night, the captain, who was himself slightly wounded, decided to land his men on Ullondo Island and sink the ship. All the boats had been shattered and the cutter that was left had to be hastily repaired before it could be lowered. With the one boat the disembarkation went on slowly during the night. At dawn the enemy's torpedo-boats were sighted. The rest of the crew jumped overboard and swam ashore, leaving a few men with the second-in-command on the ship. They ran the "Donskoi" out into a hundred fathoms of water, opened the sea-cocks, embarked in their one boat, and saw their ship go down as they pulled ashore. The Japanese sent a couple of steamers to take the crew off the island.
The torpedo destroyer that conveyed the wounded Admiral Rojdestvensky, Captain Semenoff, and a few other officers and men away from the fight was found and captured by a Japanese flotilla during the afternoon of the 28th.
