During the transit of the Indian Ocean , she acted as a scout for the main fleet and was frequently on detached duty . Conditions during the voyage were appalling , with the ship overloaded with coal for the voyage , even in the crew compartments , and the crewmen suffering from the unaccustomed tropical heat , poor food and poor hygiene and frequently mechanical failures .

" Zhemchug " arrived in Penang on 26 October for repairs and to clean her boilers . Against the advice of Admiral Martyn Jerram , commander - in - chief of the Allied Fleet , Commander Cherkassov had given most of his crew shore leave , and left the ship with all torpedoes disarmed , and all shells locked away save for 12 rounds stowed on deck . Commander Cherkassov was at the Eastern & Oriental Hotel in George Town with a lady friend . The remaining crew were having a party on board rather than keeping watch . " Emden " arrived at Penang disguised as a British warship , then raised the Imperial German naval flag , sank the and opened fire on " Zhemchug " at point - blank range with a torpedo and her main batteries .

The sentences were later commuted to 18 months by Tsar Nicholas II , but both officers were stripped of their rank , decorations and status as members of the Russian nobility .
