Despite the presence of two small submarines and a destroyer on the Soviet side, superior numbers of auxiliary cruisers gave the British ships an advantage. On 20 May, some first accidents occurred: a seaplane from the tender
Aladir Useynov crashed while on a reconnaissance mission, meanwhile two ships could not join the British task force (
Slava and
Bibi-Eybat: both suffering from engine troubles), additional engine troubles forced
Sergie and the auxiliary cruiser
Zoroaster to turn back. Still, Norris's ships could enjoy superior numbers: on 21 May, the flotilla approached Alexandrovsky Fort and the Soviets lost the patrol boat
Schastlivyy due to grounding while attempting to distract the British. Once the main battle erupted, the Soviets initially appeared victorious: a direct hit was scored on the bridge of
Kruger (but with little damage), while two direct hits caused more harm to the
Emile Nobel, which suffered 5 killed and 7 wounded. The first phase of the battle resulted in a temporary British retreat and
Emile Nobel had to pull out of the fight. Other British sources state casualties were 5 killed and 3 wounded, in addition to 3 White Russians killed and 2 wounded: none of the ships suffered serious damage. Shortly after, Commodore Norris engaged the Soviets once more, focusing the superior firepower of his ships: this time results were different when
Kruger shelled and sunk the floating battery n°2 (responsible of the previous hits on the British ships with, a loss of 12 men). The destroyer
Moskvitianin was quickly lost due to grounding after multiple failures on guns and engines. The depot-ship
Revel was full of oil and a large explosion was triggered after she was hit, mortally damaging the minelayer
Demosthenes (later scuttled). The explosion also engulfed the mine-carrier
Tuman, the auxiliary ship
Gelma, the smaller
Zoroaster (not to be confused with the British ship) and a number of small barges. The small submarine
Minoga was also damaged by fire. Meanwhile the Soviet flagship, the auxiliary cruiser
Caspian, was damaged by two direct hits. Commodore Norris halted fire, having caused serious losses to the enemy and after having spent most of the ammunition. During the battle, the Soviet submarine
Makrel attempted to move into an attack position but failed. Soviet propaganda later claimed the British halted their fire due to
Makrels action, but the British ships never noticed the danger. == Aftermath ==
