Like all missionaries, Livingstone was doomed to suffer disappointments. Thus after labouring at Kolobeng for ten years the Boers, annoyed with him for endeavouring to teach them that the natives should be treated with kindness and consideration, made an attack on his house when he was absent. They slaughtered a number of the men and women, carried away 200 children into slavery, and burnt down the mission station. Livingstone was deeply grieved about the capture of the children, but as to his own loss he merely says: "The Boers by taking possession of all my goods have saved me the trouble of making a will".
