Holograph journal of a voyage to Martinique of the three-masted ship Le Diligent. Probably not an official log, the journal was written by First Lieutenant Robert Durand and describes in detail a voyage from Vannes, France, to the coast of Guinea, each slave trade port encountered on the coast, purchase of 256 slaves at Jacquin, voyage to Martinique, selling of the slaves at St. Pierre, and return to Vannes. Also described are conditions of trade in the African and Caribbean ports, dealings between slave traders and kings and chiefs, prices of provisions, competition among slave traders, effects of climate and disease, and expenses and revenues of the voyage.
