David Livingstone and slavery "And if my disclosures regarding the terrible Ujijian slavery should lead to the suppression of the East Coast slave trade, I shall regard that as a greater matter by far than the discovery of all the Nile sources together." -- Quoted from a letter Livingstone wrote to the editor of the New York Herald. Livingstone's letters, books and journals did stir up public support for the abolition of slavery. However he became humiliatingly dependent for assistance on the very slave-traders whom he wanted to put out of business. Because he was a poor leader of his peers, he ended up on his last expedition as an individualist explorer with servants and porters but no expert support around him. At the same time he did not use the brutal methods of maverick explorers such as Stanley to keep his retinue of porters in line and his supplies secure. For these reasons from 1867 onwards he accepted help and hospitality from Mohamad Bogharib and Mohamad bin Saleh (also known as Mpamari), traders who kept and traded in slaves, as he recounts in his journals. They in turn benefited from Livingstone's influence with local people, which facilitated Mpamari's release from bondage to Mwata Kazembe. Livingstone was also furious to discover some of the replacement porters sent at his request from Ujiji were slaves.
