Service history

Russo-Japanese War

After the attack on Port Arthur on the night of 8 February 1904, which started the Russo-Japanese war ''Novik'' was the only ship to make a valiant effort and not be caught off guard. ''Novik'' would later be a part of the Battle of the Yellow Sea on 10 August 1904, however after outrunning her opponents for some time and aiding the escape of her comrades on other ships she was eventually cornered in Aniva Bay where the captain had her scuttled. However, the job was not done so well and eventually was refloated by the Japanese who would use ''Novik'' themselves for 6 years as the ''Suzuya''. Tsushima battle map-de

Of ''Izumrud'' and ''Zhemchug'', after the nighttime raid on Port Arthur the Tzar had all available vessels sent from the Baltic to the Sea of Togo to reinforce Port Arthur and reclaim the surrounding waters. At the Tsushima Straits after sailing the fleet was set upon and began to make a run for it in retreat, eventually the faster ships made in to Manila where they would seek refuge. ''Zhemchug'' was amongst those few and would therefore survive the battles. Of the 34 ships that had sailed from Russia, only 6 would survive the debacle. As for ''Izumrud'', she had decided to make a run for the Russian port of Vladivostok and had nearly managed to escape her pursuers, but in the dead of night she ran aground, just from the port. The crew escaped and would finally reach Vladivostok overland two days later. Zhemchug1906Vladivostok

''Zhemchug''s fate

As for ''Zhemchug'', she would survive into World War I, when attached with the British Asiatic Fleet in Penang and a few French ships they were set upon in a surprise raid by the German cruiser on 28 October 1914. ''Zhemchug''s main magazine store had been hit and she sank with 89 crew being killed and 143 wounded. Her commander was found negligent for being ashore with his mistress, with the magazine stores keys and having made no preparations. He would spend years in prison.
