These slaves had been liberated and added to his party, but had shown violent conduct against local people contrary to his instructions, and he feared they might have been involved in starting the massacre.
The edited version published posthumously in Livingstone's Last Journals in 1874 left out the context of Livingstone's earlier comments about Kirk and bad behaviour of the hired Banyan men, and omitted the villagers' earlier violent resistance to Arab slavers, thus portraying the villagers as passive victims.
