Boyarin was a protected cruiser. Unusually, he was built in Denmark for the Imperial Russian Navy, commissioning 1 September, 1902. Designed for 22 knots, it was found during trials that speeds in excess of 14 knots caused severe vibrations. When Boyarin was sent to the Pacific in October, he broke down in the Baltic, and had to be repaired back in the builders yard before continuing. The voyage was further complicated when Boyarin attempted to remain in the Persian Gulf for a while as a show of force in the region. The British responded with refusing to allow the Russians to coal in any of their ports, requiring them to hire a French collier to accompany the ship. Boyarin finally arrived at Port Arthur in May, 1903, and participated in exercises for the next several months, during which he was praised for economic consumption of coal. Boyarin deployed to Chemulpo (Incheon) in December as a show of force, until relieved by Varyag later that month. On the night of 8 February, 1904, Boyarin was in Port Arthur when Japanese destroyers attacked. He was not damaged in the night fighting, but deployed to meet the arrival of the main fleet the next morning. When it was discovered that this was Admiral Togo's main force, Boyarin, all alone, fired three shots before escaping into the harbor. Boyarin was subsequently assigned to minelayer escort duty, and was sent to investigate when the minelayer Yenisei ran into one of his own mines. However, Boyarin also struck a Russian mine on 12 February, and was abandoned. He ran aground, then drifted off and struck another mine, finally going down that night.
