.

For most of the first part of the battle Nebogatov's ships trailed the more powerful 2nd Squadron and were largely ignored by the Japanese so his ships were in good shape when night fell. Admiral Siniavin had not been hit at all, although Admiral Ushakov had had her bow smashed. He had ordered his ships to turn north to make for Vladivostok earlier in the day, after Admiral Rozhestvensky had been wounded, but he ordered a turn to the southwest to evade Japanese torpedo boats during the evening, but turned north during the night. Admiral Ushakov could not make the required speed to keep up and fell out. She was either sunk or scuttled by her crew during the following morning. Admiral Seniavin and General Admiral Graf Apraksin remained with him and surrendered the following morning when he was spotted by the Japanese fleet.
