(Corrects headline, lead and paragraph 2 to remove reference to British nationality) By Gordon Bell JOHANNESBURG, Feb 2 (Reuters) - A South African man pleaded guilty on Friday to the murder of Anglo-Zulu war expert David Rattray, while another man will face charges in connection with the killing, police said. South African historian Rattray, 48, a friend of Britain's Prince Charles and famous for his lively oral accounts of fighting between British troops and Zulu warriors in the 19th century, was shot dead on Jan. 26 in his lodge in South Africa's KwaZulu-Natal province. Police superintendent Phindile Radebe said one man arrested earlier this week pleaded guilty in the Pietermaritzburg High Court to charges of murder, attempted robbery and possession of an unlicensed firearm. "He is convicted, only the sentencing is now outstanding," she said. SABC News identified the man as Sethe Nkwanyana, 23, and said he would be sentenced on Monday. The second man, who has not been identified, will appear before a magistrate on Feb. 9, the broadcaster said. The two were arrested on Wednesday in a small town about 300 km (190 miles) southeast of Johannesburg after a police manhunt. Nkwanyana told the court that he and five other men entered Rattray's home with the intention of robbing it, SABC News said. Rattray was buried in KwaZulu Natal on Thursday at a funeral attended by more than 1,500 people, including a contingent of British and international journalists. Admirers praised Rattray for raising interest in KwaZulu-Natal's history, including a famous 1879 battle at Isandlwana, where more than 20,000 Zulu warriors routed British troops in one of Britain's worst military defeats. Rattray was about to finish a new history of the Anglo-Zulu conflict and was regarded as a world authority on the Zulu martial tradition. Zulus are South Africa's largest single ethnic group and have proud ties to tribal traditions that made them some of the country's most feared warriors. Rattray's killing has added to concerns about high levels of violent crime in South Africa and stoked fears that it will be unable to provide basic security when it hosts the 2010 soccer World Cup.
