during the first day of the battle of tsushima on may 27, 1905 the japanese fleet concentrated its efforts against the second pacific squadron, so nebogatov's ships survived the fate of rozhestvenski's battleships. with rozhestvenski seriously wounded, and most of the second pacific squadron's warships sunk or lost, nebogatov took over command. after facing repeated torpedo attacks during the night, the remaining russian warships assembled around "emperor nikolai i". however, on sighting the main japanese fleet on the morning of may 28, he realized that his ships were no match for the japanese fleet, and that the russian cruiser division under admiral oskar enkvist would not arrive in time to prevent his annihilation. over the objections of most of his officers, nebogatov accepted admiral togo heihachiro's terms, signing an instrument of surrender aboard togo's flagship, the battleship , and turning over control of the remaining battleships "emperor nikolai i", , "general admiral graf apraxin", and "admiral senyavin" to the japanese. however, captain vasili fersen of the cruiser disobeyed orders and escaped through the japanese lines. the captain of the battleship "admiral ushakov", having become lost during the night, was unaware of the orders to surrender, and was sunk the next morning, out-gunned and outnumbered, by the japanese fleet.
