At about 04:30 on 28 October, the Emden appeared off the George Town roads to attack the harbour defenses and any enemy vessels she might find there. Captain von Müller had disguised his ship by rigging a false smoke stack, which made the Emden resemble the British cruiser. Once he had entered the harbor, however, he ran up the Imperial Germannaval ensign and revealed his identity to one and all. He then launched a torpedo at the Imperial Russian protected cruiser, following it up with a salvo of shells which riddled the ship. As the Zhemchug struggled to return fire, von Müller launched a second torpedo. It penetrated the Zhemchug's forward magazine, causing as explosion that sank the Russian warship. Casualties among the Zhemchugs crew of 250 amounted to 88 dead and 121 wounded. The old French cruiser D'Iberville and the French destroyerFronde by now had opened fire on the Emden, but both were wildly inaccurate and von Müller simply ignored them as he turned to leave the harbour unharmed. While stopping to try to pick up a harbour pilot, he met the French destroyer, returning from a patrol. Caught by surprise, the French ship was quickly sunk by the German cruiser's guns.
Aftermath
The Zhemchug had been tied up in a state of non-readiness while her captain, Cmdr. Baron I. A. Cherkassov, went ashore that night to visit his wife. The keys for the ship's magazine had been taken ashore and no lookouts had been posted. Cherkassov watched in helpless horror from the Eastern & Oriental Hotel as his ship sank to the bottom of the Straits. He was court-martialled for negligence and was sentenced to 3½ years in prison, reduction in rank, and expulsion from the navy. His deputy, Lt. Kulibin, was sentenced to 1½ years in prison. However, Tsar Nicholas II reduced the sentences, and the two former officers were ordered to serve as ordinary seamen. Both would later distinguish themselves in combat and they were decorated with the Cross of St. George. Lt. Théroinne, who commanded the Mousquet, was among those killed in the action. Thirty-six survivors out of the destroyer's crew of 80 were rescued by the Emden. Three of the French sailors died from their injuries and were buried at sea with military honours. Two days after the battle, the Emden stopped the British steamer Newburn and transferred the remaining French prisoners to her. She was then released and conveyed the prisoners to Sabang, Sumatra, then part of the neutral Dutch East Indies. The Emden continued her successful raiding mission for another 10 days, before she was encountered by the more powerful Royal Australian Navy light cruiser Sydney. The Sydney's heavier and longer range guns enabled her to severely damage the Emden, which had to be run aground and surrendered at the Battle of Cocos.
Legacy
A total of 12 Russian sailors are buried on Jerejak and Penang island. The monument honouring the sailors of Zhemchug was twice renovated by Soviet sailors in 1972 and 1987 respectively. The battle was mentioned numerous times by Vladimir Putin on his 2003 presidential visit to Malaysia. The Russian embassy in Malaysia holds memorial services twice annually in honour of the fallen sailors.
