Cadamosto does not supply details of the return trip to Portugal. At the mouth of the Gambia, Cadamosto made a note of the near-disappearance of the northern Pole Star on the horizon, and roughly sketched a bright constellation to the south, believed to be the first known depiction of the Southern Cross constellation (albeit wrongly positioned and with too many stars – a more accurate rendition would have to wait until Mestre João Faras in 1500.) Cadamosto called it the carro dell' ostro (southern chariot). It is known that the fleet was back in Portugal before the end of the year, as Antoniotto Usodimare would write a letter dated 12 December 1455 to his creditors back in Genoa, reporting the results of his voyage (albeit with much exaggeration, and without mentioning Cadamosto). Second Journey (1456) Cadamosto set out again from Lagos in May 1456, this time not alone, but together with Antoniotto Usodimare and another caravel with an unnamed Portuguese captain, another servant of Prince Henry. The three vessels made no known trading stops, intending to sail straight to the Gambia River (probably per Prince Henry's instructions). Catching a storm around Cape Vert peninsula, the little fleet was forced to sail west, away from the coast for two days and three nights (about 300 miles) and stumbled on the as-yet-undiscovered archipelago of the Cape Verde Islands. Cadamosto, Usodimare and the unnamed captain scouted several of the uninhabited islands, believing them to be four in number (although Cadamosto notes in his account that later explorers would find them to be ten). They anchored first on an island which they named Buona Vista (Boa Vista), before proceeding on to a larger island, which they named San Jacobo (Santiago) (according to Cadamosto, on account of it being the feast of SS. Philip and James – probably an error) Finding the islands uninteresting, they headed on. (Note: although Cadamosto's claims credit for the discovery of the Cape Verde islands, this is disputed by Diogo Gomes, who claims he discovered the islands, together with Antonio da Noli, in 1462 (sometimes dated 1460)) Cadamosto, Usodimare and the unnamed Portuguese captain proceeded to enter the Gambia River again, albeit this time without opposition. They sailed about 10 Italian miles (15 km) upriver and anchored briefly on a river island they named Santo Andrea (to bury a deceased crew member, named Andrea; the island is believed to be
