Nyasaland troops who burnt Mwata Kazembe's capital to the ground, killing a number of his people, though Mwata himself had already escaped across the Luapula. Mwata Kazembe X made his way south and crossed back over the river to take refuge in the Johnston Falls Mission run by a Mr and Mrs Anderson of Dan Crawford's missionary society. (Ironically, two years before, Mwata Kazembe X had tried to have the Andersons' predecessor at Mambilima, H. J. Pomeroy, killed, but failed.) Dan Crawford and Alfred Sharpe had been involved in a similar situation in 1890–91 with Msiri (see that article). At that time Crawford's superior, Charles Swan, had encouraged Msiri to resist Sharpe's British treaty. A year later Msiri was killed by the Belgians, and the region was plunged into chaos. Now, the Andersons responded to Swan differently. While Mr Anderson kept Mwata Kazembe's men at Mambilima, Mrs Anderson took Mwata Kazembe alone to the British officers back at his burnt capital, saying "please be kind to him". Disarmed by this approach and the Mwata's agreement to accept their rule, the British agreed to let him come back. Mwata Kazembe X rebuilt his capital at Mwansabombwe. The British troops took a number of old and valuable works of art of Luba origin from the court, which they gave to Codrington. In 1920 his heirs placed them in the National Museum of Southern Rhodesia in Bulawayo, 1000 km away, where they were listed as the 'Codrington Collection'. They are still there. After the punitive expedition, Mwata Kazembe X and his successors worked with the BSAC and its successors, the British District Commissioners, and to some extent it rescued his chieftainship. The Mwata Kazembes had some influence in the colonial era because the British colonial administration ruled indirectly through chiefs. The coming of missionaries With Dan Crawford's influence Mwata Kazembe X readily agreed to requests to establish missions in the valley, especially from the Christian Missions in Many Lands and the London Missionary Society (LMS) which had sent Livingstone to Africa. In 1900 the LMS Mbereshi Mission was established 10 km from Mwansabombwe. Here schools, a church and a hospital were established, and brick makers and builders were trained, resulting in the Luapula valley enjoying a higher standard of sun-dried and burnt brick house construction than elsewhere in the region. Other Protestant and Catholic missions established schools and hospitals in the Luapula Valley
