Another ship was commanded by Tristão da Ilha, donatary captain of Machico, and another by Álvaro de Ornellas.

's knightly motto, ''Talent de bien faire'' ("Hunger for good deeds") on a tree trunk. While idling off the island, a couple of curious native canoes (five men each) from the mainland ( Wolof or more probably Lebou people) paddled out to the caravel. The first encounter went smoothly enough—gestures were exchanged expressing peaceful intentions, and several of the natives were invited aboard, and given food and drink by the Portuguese, before setting back in their canoes and returning to the mainland. Encouraged by the report of the initial pacific encounter, six more canoes decided to paddle out to the caravel. But this time Álvaro Fernandes decided to set up an ambush, and prepared a launch with armed men, behind the concealed side of the caravel. As the native canoes got within range, Fernandes gave the signal and the hidden Portuguese armed launch darted out from behind the ship. The native canoes immediately began to turn around to make their way back to shore, but not before the Portuguese boat reached the closest African canoe. Cut off, the native crew leaped overboard and tried to swim back to shore. Two of the swimmers were captured by the Portuguese, but put up such a fight that by the time the second man was captured and subdued, all the others had made it safely to the mainland. The ambush had yielded only two captives, and raised the alarm on the mainland shore. With the element of surprise now gone, Álvaro Fernandes saw little point in remaining in the vicinity, and set sail out of Bezeguiche bay. He proceeded south along the Petite Côte a little way, until he reached an imposing cliff rock he called the ''Cabo dos Mastos'' ("Cape of Masts", on account of a set of dry, naked tree trunks, which resembled a cluster of ship's masts; now Cape Naze, ). Fernandes ordered a launch to scout the nearby area. They came upon a small hunting party of four natives (possibly Serer) in the vicinity, and tried to capture them by surprise, but the startled hunters managed to escape and outrun the Portuguese. Alvaro Fernandes returned to Portugal thereafter, with the two captives from Bezeguiche, the barrels of Senegal River water and the hunters' weapons to show for it. His hostile action had raised the alarm among the populations around Bezeguiche bay. The next Portuguese ships to arrive in the area—the large slaving fleet of Lançarote de Freitas a few months later—would be greeted by a hail of arrows and poisoned darts, and forced away. Álvaro Fernandes sailed further south than any prior Portuguese captain, setting up the Cape of Mastos as the farthest marker. For that, he and his uncle,

, were amply rewarded by Prince Henry.


2nd expedition

In the following year, João Gonçalves Zarco set out again on a caravel, commanded by his nephew Álvaro Fernandes. Fernandes headed straight to his last point (Cabo dos Matos), and landed a little exploring party, but finding nobody, re-embarked and continued sailing on. At an indeterminate point south of there, they spotted a local coastal village and disembarked a party, only to be met by an armed native force (probably Serer), intent on defending their village. Álvaro Fernandes killed what he believed was the native chieftain at the beginning of the encounter, prompting the rest of the local warriors to briefly halt the fight. The Portuguese landing party availed themselves of the pause to hurry back to their ship. Having sailed a little on, the next day, the Portuguese captured two young local women collecting

on a similar river venture, Alvaro Fernandes nonetheless decided to set a launch to explore upriver. The first exploratory boat made a landing on the bank near some local huts, where they quickly captured a local woman and brought her back to the caravel. Then refitting the boat, they set out again, this time intending to sail further upriver. But they did not get far before they came upon four or five native canoes with armed men heading towards them. Fernandes immediately turned the boat around and began racing back to the caravel, with the canoes hot on his tail. One of the canoes went fast enough to nearly catch up with Fernandes's boat, prompting Fernandes to turn and prepare for a fight. But the lead native canoe, realizing it was alone, slowed down to wait for the others, thus giving the Portuguese boat the opportunity to resume their flight back to the caravel. The Portuguese escaped, but Álvaro Fernandes himself was gravely wounded in the leg by a

shot from one of the canoes. Once aboard ship, he disinfected the wound with urine and olive oil. He lay in fever for a few days, on the edge of death, but recovered. Despite the near-fatal experience, the caravel proceeded straight south for a little longer, until they reached a sandy cape and large sandy bay. They put a small boat to explore near the beach, but found a force of some 120 natives, armed with shields,

s and bows marching towards them. The explorers immediately returned to the caravel. Nonetheless, the armed native party gave what seemed like a peaceful festive demonstration from the beach - waving and inviting the Portuguese to land. But given Fernandes's ill condition and still shaken by their earlier near-escape, the decision was made to quit the area and set sail back to Portugal. On the way home, Fernandes stopped by

Extent of explorations

Of all the Henrican captains of the 1440s, Álvaro Fernandes seemed to have pushed the discovery marker farthest. It is almost certain that, on his first expedition (1445), Álvaro Fernandes surpassed all others and was the first European to land on ''Bezeguiche'' (

), that would lead us to identify the "Rio Tabite" with the Forecariah River in modern Guinea, implying Fernandes sailed a tremendous 135 leagues beyond Cape Vert, well beyond the 110 suggested by Zurara. At the other extreme, the Viscount of Santarém identified the ''Rio Tabite'' with the ''Rio do Lago'' ( Diombos River, in the Sine-Saloum Delta of

), a mere 24 leagues from Cape Vert. However, the Diombos is the prime candidate location for the death of

Modern historians believe both Zurara and Barros greatly exaggerated in implying Álvaro Fernandes reached modern Guinea. In particular, it is highly unlikely he would have sailed past the huge

and other notable promontories and landmarks without exploring them or making the least mention of them. Moreover, Zurara claims that all along Fernandes's route from Cape Vert, the "coast tendeth generally south", thus eliminating the wilder estimates (the coast runs steadily southeast after Cape Roxo). Reviewing the evidence, Teixeira da Mota suggests that the "Tabite" river Fernandes sailed up was probably the

). That means Fernandes really sailed 50 leagues (not 110) beyond Cape Vert. That still makes it the farthest point reached by the Portuguese discoveries of the 1440s. The only real difficulty with the Casamance hypothesis is the use of poisoned arrows, which was common among the Serer, Nimoninka and Mandinka peoples of the Saloum-Gambia area, but not among the

(''Felupes'') of the Casamance. But historians doubt whether Fernandes was actually hit with a poisoned arrow at all, rather than a regular arrow and simply suffered a common infection in the aftermath. The very fact that he survived suggests it was not poisoned, as does the fact that no other sailors reported any similar injuries. (It contrasts sharply with the fate of
Nuno Tristão Nuno Tristão was a 15th-century Portuguese explorer and slave trader, active in the early 1440s, traditionally thought to be the first European to reach the region of Guinea (legendarily, as far as Guinea-Bissau, but more recent historians believ ...
and his crew in the Diombos River, where a score of men fell dead quickly from Niominka poison. Given Tristão's fate, Zurara may have simply assumed all tribes south of Cape Verde used poison.) The other footnote is why Fernandes' caravel was ambushed on the river by the Jola of the Casamance, who were unfamiliar with the Portuguese. Teixeira da Mota points to the abduction of the woman on the bank may have alerted the river peoples to the hostile intentions of the Portuguese. This contrasts with the Jola people on the beaches of Cape Varela, whose festive reception and hailing to the Portuguese ships from the shore reveals they had little or no prior notion of Portuguese slavers.Teixeira da Mota, p.282-83 Unfortunately, Zurara reports no topographic names bestowed by Álvaro Fernandes on his second journey, and the imprecise magnitudes reported ("some days", "a certain distance") are not very elucidating, leaving this conclusion still open to dispute. All that seems certain is that Fernandes sailed beyond his previous marker in 1446, and that this would remain standing as the record length reached by the Portuguese discoveries for the next decade. Fernandes's marker was only surpassed ten years later, in 1456, by Alvise Cadamosto, a Venetian explorer in Henry's service. Cadamosto laid claim to be discoverer of the
