The captain of a ship kept a daily log of the voyage. These entries by Captain Miller in his log of the voyage from Bristol to the Gold Coast of Africa record purchases and deaths. The Black Prince, owned by James Laroche & Co, sailed from Bristol on 5th May. Eight months were spent on the coast, buying enslaved Africans, often only one or two at a time. '3 August The Pinnace returned Brought some rice but no slaves ... 20 September Some canoes came on board with some slaves but could not buy any but One Man ... 6 November Brought off 14 Males and 12 Female slaves'. The enslaved Africans planned an insurrection at the coast, and again when the ship was at sea. Both revolts were discovered and controlled by chaining up the men, and flogging the leaders. '22 February found the Slaves was intending to rise got all under arms and soon got them quieted tho a great Number of them had Broke there Irons ... found out 2 of which was the Ring Leaders which was well Flogged ... 4 March [at sea] The slaves intended to make the other Attempt.
