modern Dog Island). The trio proceeded upriver carefully, warily watched by native Mandinka canoes, but this time no hostilities or ambushes emerged. Eventually, one of the interpreters managed to entice some of the canoe-borne natives aboard the Portuguese ships and opened peaceful contact. The natives identified themselves as subjects of king Forosangoli (of the southern bank of the Gambia) and that he, and most other Mandinka kings along the Gambia river were all vassal subjects of the Emperor of Mali (Impatore di Melli), and that some of the local kings were willing to meet the Portuguese. Following the instructions of his interlocutors, Cadamosto sailed some 60 Italian miles up the Gambia river, reaching the residence of the Mandinka king he called Battimansa, Mandinka for "king of the Batti' (probably Badibu, on the north side of the river). They were well received, but disappointed at the little evidence of the large amounts of gold they had expected to find. They engaged in some petty trade with the locals, in particular musk (invaluable to European perfumers), and imply they even acquired live specimens of African civet cat. Cadamosto mentions interacting with another lord, Guumimensa, whose dominion was closer to the mouth of the river. This is probably none other than the formidable 'Niumimansa', king of the Niumi-Banta of Barra region, whose rule extended over Niumi-Bato (Niominka) of the Diombos River shore, an old antagonist of Portuguese explorers. However, Cadamosto reports their relations went quite smoothly. Cadamosto and his companions stayed in Badibu for 11 days, before departing. They did not discover the commercial center of Cantor, which was still several miles upriver (it was only discovered a couple of years later, by Diogo Gomes). But he did discover malaria, and his crew quickly fell ill with fevers. It was probably this epidemic that prompted Cadamosto to cut short his stay and leave the Gambia river, back to the ocean, where the fevers seemed to have subsided. Resolved to continue exploring the West African coast, Cadamosto's trio set sail south, doubling Cape St. Mary () and carefully navigating the dangerous breakers around Bald Cape (), reporting a couple of rivers along the way (none of which he names). A few days later, Cadamosto and his companions discovered the mouth of the Casamance River (). They named the river after the local lord Casamansa, king ('mansa') of Kasa (called Casangas by later Portuguese, a
