Zurara, Ch. 87 (p.p.258) (Port: p.406). Barros (Dec. I.1, Ch.14, p.121). Quintella (p.149) and Diffie and Winius (p.86-87) place this in 1446. Faria e Sousa (p.528) in 1447.

Another source, the 1911 Encyclopædia Britannica (op. cit), describes Fernandes as having sailed to "perhaps in the neighborhood of Conakry...but little short of Sierra Leone."
