c. June 10, 1502 - Chronicles differ on what exactly happens after the first squadrons double the Cape. Following the account of Gaspar Correia (p. 272), Vasco da Gama was among the first ships to arrive in Mozambique Island, the pre-arranged meeting point. Gama is immediately recognized by the local sheikh (with whom Gama had a tussle on his first journey back in 1498).[40] The Mozambique ruler immediately offers his pardon for that affair and puts supplies at the disposal of the tempest-tossed Portuguese. Vasco da Gama remains in Mozambique for a while, waiting for the rest of the battered fleet to trickle in, one by one.

The only known loss is the small nau Santa Elena, captained by the novice Pêro de Mendonça, which captured by bad currents around Cape Correntes, ends up running aground near the banks of Sofala.[41] However the crew is safely rescued by the passing ships of Francisco da Cunha Mareco (Bretoa) and Fernão Rodrigues Bardaças (Santa Marta).[42] With surfeit of crew from the capsized Santa Elena, Gama orders the construction of a whole new caravel from scratch on Mozambique Island.[43]

Although not mentioned in all sources, the caravel of António do Campo ('Antão Vaz' in Correia), is said to have been badly battered at Cape Correntes, and drifted backwards into Delagoa Bay (Maputo). Campo will not rejoin the 4th Armada on time for the Indian Ocean crossing, and thus remain stuck in Africa until next year. See below.[44]

According to Correia, while repairing on Mozambique Island, Vasco da Gama dispatches Pedro Afonso de Aguiar (captain of the Leitoa) and two caravels south to the city of Sofala, the entrepot of the Monomatapa gold trade.[45] Sofala had been missed by all prior armadas, but not this time. Following up on the scout report of Sancho de Tovar from the previous year (see 2nd India Armada), Aguiar leads the first Portuguese ships into Sofala harbor. Aguiar goes ashore, initiates some trade in the local markets while seeking out the local ruler, the sultan or shiekh Isuf of Sofala (Yçuf in Barros; Çufe in Goes). An audience is arranged and Aguiar draws up a commercial and alliance treaty between Portugal and Sofala. Matters settled and gifts exchanged, Aguiar takes aboard a Sofalese ambassador to meet Vasco da Gama back in Mozambique.

In other accounts, (principally Osório (p. 192), mildly corroborated by other chroniclers and the anonymous Portuguese eyewitness and Matteo da Bergamo) it is Vasco da Gama himself, and not Aguiar, who goes to Sofala. According to this alternative account, Gama did not go to Mozambique immediately after the Cape crossing; rather, most of the fleet met at some unnamed bay just a few leagues north of Sofala (possibly the 'Rio dos Boms Sinaes'); Gama ordered Vicente Sodré with the main fleet ahead to Mozambique Island, while he remained behind [46] The construction of the new caravel was thus overseen by Sodré, not Gama. After accounting for all the ships and sending them on to Mozambique, Vasco da Gama himself sailed south with four ships to Sofala, conducted some trade and opened the first contact with the Sofalese ruler.[47] That would mean Gama was the last to arrive in Mozambique. In this alternative account, the lost ship of Mendonça (or Fernandes) was one of the four that went with Gama to Sofala, and capsized while exiting the Sofala banks.

Late June, 1502 - Vasco da Gama makes arrangements to leave Mozambique. A Portuguese factory is established on Mozambique Island, with Gonçalo Baixo as the factor, with some ten assistants, to capitalize on the results of the Sofala trade mission.[48] The new caravel finished, Gama christens it Pomposa and places it, together with some 30 crew, under the command of João Serrão (of future Magellan fame), with instructions to take any goods from the Sofalese trade.[49] According to Correia, Gama was unwilling to wait around for the results of Aguiar's mission to Sofala, and set sail out of Mozambique before Aguiar's returned from Sofala. As a result, Aguiar was forced to leave the Sofalese ambassador in Mozambique (letting him find his own way back home) and set sail for Malindi, hoping to catch Gama there.[50]

East Africa, c. 1500. The Kilwa Sultanate held formal sway from Malindi in the north, to Cape Correntes in the south.

Gama had gone first to Kilwa (Quiloa). The dominant city-state on the East African coast, Kilwa Sultanate was the formal overlord of Mozambique and Sofala. If the fledgling Portuguese trade presence in those East African towns was to remain unmolested, then the Portuguese must secure Kilwa's consent. Cabral and the 2nd Armada had tried, and failed, to secure a treaty with Kilwa back in 1500. Gama decided to try again – and was determined not to take no for answer. But, mindful of the lesson at Calicut, Gama also wanted to add a touch of intimidation, to show off his heavily armed fleet and impress upon the Sultan of Kilwa the consequences of interfering or turning back on any agreement.

On July 12, 1502, Gama's large, menacing armada arrived at the island-city of Kilwa. Gama sent for the Kilwa ruler, Emir Ibrahim, inviting him aboard the São Jeronimo, to negotiate a treaty of peace and trade.[51]

Sensing a trap, Emir Ibrahim first asks for a safe-conduct (which da Gama promptly gives him), but fearing treachery, the emir changes his mind, and refuses to go aboard. However, after much discussion, one of his advisors, a certain wealthy nobleman Muhammad ibn Rukn ad Din (called Muhammad Arcone or Ancone or Enconij by the chroniclers [52]) finally persuades the emir to take up the Portuguese offer. Emir Ibrahim is ferried to the flagship and climbs aboard. After minimal opening cordialities, and ostentatious proclamations of friendship, Gama lays down his price: a treaty with Portugal has to be paid for with a hefty cash tribute to the King of Portugal. The emir is dismayed. Declaring tribute to be a dishonor, he refuses. Gama threatens to level the city and lay it to fire and waste. Emir Ibrahim, effectively captive on board, reluctantly agrees, and signs a treaty making Kilwa tributary to Portugal. Leaving the Kilwan nobleman and advisor Muhammad Arcone aboard as a hostage, the emir returns to shore to make the arrangements.

mid-July, 1502 - After a few days of lingering in Kilwa harbor and no sign of the emir's promised tribute, Gama dispatches a messenger to see what the delay is. Emir Ibrahim sends a message back declining to dispatch the tribute, and telling the Portuguese captain-major that he can do whatever he will with the hostage Muhammad Arcone, given that his poor counsel had proven him unworthy. The angry Gama throws Arcone into a long-boat, without water or shade, to die of heat and exposure. Nonetheless, Muhammad Arcone is a wealthy man in his own right, and servants from his household offer Gama a substantial ransom to release him. Knowing the hostage is otherwise worthless to him, Gama consents.

The Custódia de Belém, forged from Kilwa tribute

July 20, 1502 - His vengeance on Muhammad Arcone's bad counsel satisfied, the Emir Ibrahim of Kilwa finally decides to send some tribute - some 1500 gold meticals[53] - to satisfy the Portuguese captain-major. Vasco da Gama, anxious not to miss the monsoon winds to India, takes what he can get.[54]

[The extorted gold coins of Kilwa were used by the goldsmith Gil Vicente in 1506 to make the famous gold pyx or monstrance known as the Custódia de Belém, for the Jerónimos Monastery in Belém. It is considered by many to be one of the most magnificent treasure pieces of the Portuguese crown.]

[Correia (p. 282) reports a little knot before departing: several dozen Kilwan women 'picked up' (read: abducted) and taken aboard the ships by bored Portuguese sailors for fun and amusement refuse to return ashore. Although Emir Ibrahim promises that they will be unharmed, he cannot guarantee that those who allowed themselves to be baptized Christian by enthusiastic chaplains on the ships will be taken back by their families. Much to the delight of the crew, Gama reluctantly allows these to come with them.]

c. July 15, 1502, In the meantime, part of the third squadron, the trio that held with Estêvão da Gama (Gama, Dias, Carmona) arrive at Mozambique Island, half-famished and heavily damaged. At that same time, the remaining pair (Vasconcellos, Buonagrazia) alight at the Sofala banks. The two squads do not reconnect with each other. Estêvão da Gama's trio, following the itinerary left in Mozambique by his cousin, heads off to Kilwa [55] Alone idling before Sofala, Vasconcellos and Buonagrazia proceed north to the mouth of the Rio de Bons Sinaes (Zambezi River), where they put in for repairs and recuperation.

On July 23, 1502, part of the third squad (Estêvão da Gama, Lopo Dias and Thomas de Carmona) arrived in Kilwa, just in time to reconnect the main armada of Vasco da Gama, preparing to depart from Kilwa harbor.[56] At that moment (July 22 actually), the remaining two ships of the third squad (Vasconcellos, Buonagrazia) finally arrive in Mozambique Island. Taking note of the notes and itinerary left behind, they set sail for Malindi, hoping to catch the main fleet there.

Late July, 1502 - Vasco da Gama arrives in Malindi, just in time to be met by Pedro Afonso de Aguiar (from Sofala), who reports to him the results of the Sofala treaty.[57] Gama's fleet does not actually dock in Malindi - they intended to, but miss it, landing a few leagues ahead, unable to turn back because of the weather (although they manage to get some supplies and exchange messages with Malindi emissaries that row out to them).[58]

On July 29, 1502, Vasco da Gama's fleet departed its anchorage near Malindi for its Indian Ocean crossing. He was missing three ships: Campo, Vasconcelos and Buonagrazia.

August 2, 1502 - The remaining two ships of the third squadron (Lopo Mendes de Vasconcelos and Giovanni Buonagrazia) arrive in Malindi, just a few days after Gama's departure. They are well received by the Sultan of Malindi.[59] They pick up a few letters left with degredado Luiz da Moura in Malindi by the returning fleet of João da Nova a few months earlier, reporting the latest Indian news.[60] They do not stay long, but immediately set sail after Gama's fleet.

Delagoa Bay, now Maputo Bay

The last missing ship - António do Campo's caravel from the first squadron - will not make it across to India this year. As already alluded to earlier, the caravel of António do Campo ('Antão Vaz' in Correia) is said to have been caught up and battered by bad winds at Cape Correntes and forced to drift with the current of the Mozambique Channel aimlessly southwest. Campo's caravel is said to have alighted at Delagoa Bay (now Maputo Bay). The hitherto unknown capacious bay is watered by three rivers: the Maputo river to the south, the Espirito Santo 'river' to the west (actually an estuary formed by the Umbeluzi, Matola and Tembe rivers) and the Maniça (now Incomati) river to the north. Being told by the local inhabitants that the Espírito Santo 'river' was sourced from a great lake deep in the interior, Campo names it Rio da Lagoa (River of the Lagoon), from which we get the name by which Maputo Bay was long known: 'Delagoa Bay'.[61]

Having been forced to linger at Delagoa for repairs, António do Campo hurries north to try to make junction with the rest of the 4th Armada at Malindi, but arrives too late (mid-September). The fleet having already left for India, and the monsoon winds preventing Campo's own crossing to India. António do Campo will remain behind on the East African coast until next April.[62]

c. August 20, 1502[65] Gama's fleet reaches Anjediva island. The next day, the ships of Giovanni Buonagrazia (carrying Thomé Lopes) and Lopo Mendes de Vasconcellos (Juiloa) finally catch up with the rest of the armada.[66] Save for the ship of Campo (still stuck in Africa) and Serrão (on patrol around the Mozambique factory), all the Portuguese fleet (18 ships out of the 20 that left Lisbon) are together and accounted for.[67]

Around Anjediva island, the armada spots three boats belonging to Timoja, the Hindu privateer who operates out of Honnavar (Onor), on the frontline between the warring states of Muslim Bijapur and Hindu Vijayanagar.[68] They give chase unto the mouth of the Sharavathi River, at which point the pirate boats slip into harbor of Onor. Assured by Gaspar da Gama (Goese Jew and translator) that Onor is a corsair's nest, Vasco da Gama orders an attack on the city. Portuguese landing crews attack the harbor, plundering and setting fire to the ships and docks.[69]

The day after the raid on Onor, the 4th Armada arrives at the mouth of the river that leads up to the city of Bhatkal (Batecala), south of Onor. Perceiving what he considers hostile gestures from shore, the captain-major dispatches his cousin, Estêvão da Gama upriver to the town to investigate.[68] Surveying the Batecala docks, Estêvão spies several Arab merchant ships and prepares for hostilities. But his attention is soon drawn to a small group of men in ornate robes, rushing down to the docks, frantically calling to him. It is an embassy from the raja of Batecala, requesting an immediate audience with the Portuguese captain-major.

Estêvão brings the embassy to his cousin. Evidently hearing of the fate of Onor, the embassy offers to submit to the Portuguese. Vasco da Gama agrees to leave Batecala in peace in return for a yearly tribute of 1,000 bags of plain rice and 500 bags of quality rice (probably Basmati). Batecala is also to agree to the exclusion of the Arab merchants from the city, that no pepper trade is to be carried at this port, and that no ship be allowed to travel between Batecala and Calicut. The treaty is set down in writing and signed.[70]

[Batecala is described by Correia as just a modest rice, iron and sugar port south of Onor; it was actually the principal port and sea outlet of the Vijayanagara Empire, and its primary line was the horse trade, specifically, importing large numbers of splendid Persian and Arabian horses for the armies of Vijayanagara princes.[71]]

Late August/Early September 1502 – Business in Batecala done, Vasco da Gama sets sail towards Cannanore. They anchor in around Mount d'Eli, the common touch-point for ships on the Jedda-Calicut route, evidently intending to catch some prizes before proceeding.

September 29, 1502 – After prowling around Mt. d'Eli for nearly a month with little success (they captured only one minor ship[72]), captain Gil Matoso (on the São Gabriel), spots a large merchant ship carrying Muslim pilgrims returning from Mecca (or going to it, chronicles contradict). The ship, the Miri, is identified as belonging to a certain al-Fanqi, one of wealthier men of Calicut and said by some to be the Meccan factor in Calicut.[73] Matoso chases the pilgrim ship down,[74] which surrenders rather quickly, probably imagining that its master had enough money to ransom it off. But Vasco da Gama shrugs off all the offers. As the Portuguese crew plunder the ship and transfer its cargo, it quickly becomes evident that Gama intends to burn the ship with all its passengers – men, women and children – on board. When Gama proves deaf to their pleas for mercy, the passengers frantically attack the Portuguese men-at-arms with their bare hands, to no avail.

October 3, 1502 – a day, eyewitness Thomé Lopes states, "I will never forget for the rest of my days".[75] The pilgrim ship thoroughly plundered, on Gama's orders, the passengers are locked in the hold and the ship burnt and sunk by artillery. It takes several days to finally go down completely. Portuguese soldiers row around the waters on longboats mercilessly spearing survivors.[76]

The sinking of the Miri is an act that will instantly cement Gama's cruel and fearsome reputation, and generate a great deal of hatred for the Portuguese in India. Gama defended his act as "vengeance" for the Calicut massacre of 1500, arguing that the ship's owner, as a prominent person in Calicut, was 'doubtlessly' responsible for the sinister counsel to the Zamorin that led up to it.[77]

Of the eyewitnesses, all mention it, but only Thomé Lopes openly condemns the act, claiming Gama acted "with great cruelty and without any mercy whatsoever".[78] The chroniclers do not shy away from describing the event and their unease is evident. Although Barros and Castanheda reiterate Gama's justification of the act as revenge for Cabral, they do not seem to embrace it themselves.[79] Indeed, Barros, Góis and Osório claim the ship belonged to the Sultan of Egypt, who was in no way responsible for the events in Calicut, thus subtly suggesting Gama may have made a mistake.[80] Gaspar Correia is a little more open in his disapproval. He notes that several of the Portuguese captains were appalled by Gama's decision and tried to persuade him against it (if only because they would forego a hefty ransom).[81] Correia gives a heart-rending account of the desperate and valiant resistance of the doomed passengers.[82] Poet Luís de Camões passes over the incident in silence, evidently feeling it detrimental to the heroic portrait of Vasco da Gama.[83]

Estimates of those killed on the Miri hover around 300.[84] Portuguese chroniclers are eager to report that 20 children were spared this fate, and brought back by the 4th Armada to Lisbon, where they will be baptized and raised as friars at the Nossa Senhora de Belém.[85] Among the eyewitnesses Thomé Lopes and the anonymous Flemish sailor make no mention of this small mercy, although Matteo de Bergamo does point it out.[86]

Malabar Coast of India, c. 1500, showing the path of Vasco da Gama's 4th India Armada in 1502

October 18, 1502 – Vasco da Gama's armada finally reaches Cannanore (Canonor, Kannur), and delivers the Cannanore ambassador that had gone to Lisbon with Cabral's 2nd Armada.[87] The Kolathiri Raja of Cannanore invites Gama to come ashore for an elaborate reception, but Gama replies that he swore a personal oath not to set his foot on Indian soil again until his vengeance on Calicut was sated. As a result, the rajah orders a wooden scaffold to be built over the seashore, where they can meet in person without violating the vow.[88]

Gama presents the raja with royal letters and munificent gifts (a jeweled sword, a brocaded armchair) and discussions immediately begin. A commercial treaty is negotiated, establishing a Portuguese crown factory in Cannanore, and arranging a fixed-price schedule, which the Raja personally guarantees, for the sale of spices to the Portuguese.

The negotiation for the commercial treaty did not go smoothly, particularly the fixed price clause. The Kolathiri Raja protested that he had no power over market prices nor the right to dictate how private merchants disposed of their property.[89] Gama had to resort to feints, threats and then sailed out of Cannanore in anger.[90] Barros credits the role of Paio Rodrigues, the Portuguese factor (private, not crown, an employee of the private employee of D. Álvaro of Braganza and the Marchionni consortium), that had been left behind in Cannanore by João da Nova's Third Armada at the beginning of the year. After Gama stormed off and ordered sail out of the city, Paio Rodrigues mediated between the Kolathiri Raja and the Captain-Major and finalized the treaty [91]

Correia points out this is the treaty where the Portuguese cartaz system was first introduced.[92] Henceforth, every merchant ship along the Malabar coast had to present a certificate signed by a Portuguese factor (in Cannanore, Cochin, etc.), or else be subject to attack and seizure by a Portuguese patrol. This licensing system would be subsequently adopted later on other Portuguese-controlled coasts (e.g. East Africa, Malacca, Brazil), with differing degrees of success.[93] It will be largely maintained until the 18th century.

October 25, 1502 – Fleet departs Cannanore. Chroniclers differ a little on the subsequent sequence of events. While still in Cannanore, Gama had sent Pedro Afonso de Aguiar to Calicut in advance, with the warning that he had come to settle scores for the mistreatment of Cabral and to get compensation for the overrunning of the Calicut factory in 1500. In response, the Zamorin of Calicut sent back a string of messengers to Cannanore (and along the way to Calicut), each delivering promises that the Zamorin was willing to settle matters with Gama, and compensate the Portuguese for the loss of their factory goods.[94] On the other hand, Gama also receives a message from Gonçalo Gil Barbosa, the Portuguese crown factor in Cochin, warning him that it was all a tactical ruse, that the Zamorin of Calicut had also dispatched a circular letter to all the lords of the Malabar Coast instructing them to close their ports and markets to the Portuguese.[95]

October 29, 1502 – Gama's large armada finally arrives before the harbor of Calicut (Calecute, Kozhikode). The Zamorin dispatches an emissary, a Brahmin (dressed as a Christian friar) on a boat to Gama.[96] The Brahmin reports that the Zamorin had arrested twelve of those responsible for the 1500 riot, and offers a peace and friendship treaty and the opening of a discussion of the restoration of the trade goods seized from the Portuguese factory, albeit noting that the Zamorin has also suffered property damages from Portuguese actions and that he intends to deduct it from the final account.[97] Gama is angered, feeling that the Zamorin has changed his tone from his earlier messages, and demands the property taken from the factory be restored in full and brought to his ship, and that all Muslim merchants must be expelled from the Calicut, before any discussion about a treaty begins.[98]

While awaiting the Zamorin's reply, Gama seizes a nearby idling zambuq and some fishing boats that had unwisely ventured into Calicut harbor, taking some fifty fisherman captive.[99] This action evidently angers the Zamorin, who sends a stern reply to Gama, noting that Gama had already taken severalfold times more property from Calicut ships, and slaughtered ten times more of his citizens (on the Miri, etc.) than the Portuguese lost in the 1500 riot. Despite being the net sufferer and the clamor of his citizens for revenge, the Zamorin is prepared to forgive and forget and start anew.[98] The Zamorin also replies that Calicut is a free port and he has no intention of expelling 'the Moors'.[100] Moreover, the Zamorin orders Gama to release his 'hostages', that he will not subject himself to negotiation conditions and that if Gama is unhappy with his offer, then he should leave Calicut harbor at once, for the Zamorin has not given him permission to anchor there, or at any other port in India.[101]

October 31, 1502 – Infuriated by the reply, Gama sends out a strongly worded ultimatum, declaring that the Zamorin's permission means nothing to him, that he has until noon the next day to deliver the Portuguese factory goods to his ship.[102] Gama uses this overnight interlude to send his boats out to sound the harbor of Calicut to find optimal firing positions. That same night, Calicut forces set about frantically digging entrenchments, erecting a protective timber palisade and laying cannon along the harbor shore.[103]

November 1, 1502 – At noon, having received no reply, Gama orders that his Malabari prisoners be strung up by their necks from the shipmasts, allocating a few to each ship.[104] Calicut crowds approach the beach to watch the grisly spectacle. Then the armada advances into the harbor and opens fire. The bombardment is principally aimed at clearing the beach and trenches.[105] The Malabari shore cannons are too few, their range and power too weak, to provide an effective reply.[106] The bombardment continues until nightfall. That night, the corpses of the hung Malabaris are taken from masts, their feet and hands severed off and sent by a small boat to the beach, with an insulting message to the Zamorin, including a demand that the Zamorin reimburse the Portuguese for the powder and shot expended on destroying his city.[107]

November 2, 1502 – The city bombardment resumes the next morning. The mostly poor dwellings on the shore having been razed the previous day, the Portuguese cannons now have a clear view of central city and the statelier homes of the richer citizens of Calicut and bring their larger ordnance to bear.[108] The city is relentlessly bombarded all morning – some 400 large rounds and an indeterminate number from the smaller caliber guns [109] At noon, when the Portuguese pause for lunch, a small group of Malabari vessels tries to attack the idling squad, but are quickly seen off.[110]

November 3, 1502 – Barros reports that the two-day bombardment had sufficiently crippled the city that several of the captains urge Gama to authorize a landing of troops to sack Calicut. But Gama, still hopeful the Zamorin might come to terms, turns down their request, believing a sack would only escalate matters to the point of no return.[111] So, the next morning, vengeance satisfied, Gama sets sail out of Calicut harbor.

[In his somewhat different account,[112] Gaspar Correia does not report the hanging of the prisoners; instead, after the bombardment, while still anchored before the harbor of the smoldering city, the 4th Armada captures a Coromandel merchant convoy of 2 large ships and 27 small boats unlucky enough to turn up at Calicut at that very moment. Seizing the convoy, Gama orders the cargoes transferred, the crews tied, their teeth beaten out, their noses and hands cut off and the ships set alight. The Brahmin emissary (still being held by the Portuguese) is sent back to shore with a bag full of severed hands and a note for the Zamorin telling him to "make a curry out of them".[113]]

The violent treatment meted out by Vasco da Gama sends shockwaves throughout the Malabar coast. Merchant ships in Indian ports hurriedly leave the area or go into concealment. All shipping along the coast essentially freezes.

Before leaving Calicut, Gama assembles a squadron of five or six fighting ships under Vicente Sodré and his brother Brás Sodré, with some 200 soldiers (mainly crossbowmen), to maintain the blockade on Calicut harbor, and patrol the coast preying on Calicut shipping. The exact composition of the patrol squadron differs in the sources, and it seems there is some reshuffling of captains in the process. The following is only one possible list, compiled from different sources, and should not be taken as authoritative:

The patrol squadron captains are taken from the lists in Castanheda,[114] Góis[115] and Osório[116] Other sources are not so explicit.[117] The ship names are tentatively deduced from Gaspar Correia, who, as usual, deviates in naming the captains.[118]

November 3, 1502, His blockade of Calicut in place, Vasco da Gama arrives in Cochin (Cohim, Kochi) with the bulk of the armada. He is received by Trimumpara ruler of Cochin, not without a touch of anxiety. But cordialities soon set that to rest. The Nair hostage taken accidentally by the 2nd Armada the previous year is delivered, along with the letter of the other Nair who stayed back in Lisbon.

Gama concludes negotiates a new commercial treaty with the ruler of Cochin, this time with a fixed-price schedule, like at Cannanore. Diogo Fernandes Correia, the new designated factor for Cochin, relieves Cabral's factor Gonçalo Gil Barbosa (now slated to be transferred to Cannanore). They promptly set about their business of buying spices and loading ships in Cochin for the return journey.

While conducting business at Cochin, Vasco da Gama receives a letter from the queen-regent of Quilon (Coulão, Kollam), on behalf of her young son, the raja Govardhana Martanda. The queen invites the Portuguese fleet to load up with spices at Quilon. Gama declines politely, noting that he cannot do anything without the permission of his Cochinese hosts. As a result, the queen-regent dispatches a messenger to the prince of Cochin. Trimumpara Raja prevaricates at first, fearing that competition from Quilon's more amply-supplied markets will hurt his own. But Cochin's slender supply is worrying the Portuguese factors. At length, an agreement is reached between all parties: Gama is to dispatch only two ships to load up with spices at Quilon, and promises not to set up a permanent factory in that city. The two ships, carrying temporary factor João de Sá Pereira, the first Portuguese to enter Quilon, will load up quickly, and return to Cochin within ten days.[119]

November 19, 1502 – While at Cochin, Gama receives a message from Syrian Christian community of nearby Cranganore offering to place themselves under the protection of the King of Portugal.[120] Gama accepts their gift of a red silver-tipped sceptre, a symbolic command staff, but notes that he personally cannot do much, as he will be leaving soon. But he promises that the community can call on the Portuguese naval patrol of Vicente Sodré at any time, should they need anything.

January 3, 1503 – A wealthy Brahmin, accompanied by his son and nephew, shows up Cochin and requests permission from Vasco da Gama to take passage on the 4th Armada to Portugal. At first the Brahmin claims he seeks to learn more about Christian religion in Europe, but eventually reveals he is in fact a plenipotentiary ambassador of the Zamorin, and that he hopes to speak directly with King Manuel I of Portugal in Lisbon, and negotiate a permanent peace treaty between Portugal and Calicut, as (in the Zamorin's estimation) the Portuguese armada captains, coming and going every year, do not seem empowered to negotiate durable treaties.[121] Gama assures him he is fully empowered by the king, at which point the Brahmin then offers to mediate a peace treaty between Gama and the Zamorin. Gama agrees, and the Brahmin returns to Calicut, coming back to Cochin shortly after accompanied by a Nair of the Zamorin's household, with a concrete offer to compensate the Portuguese for the goods lost in the Calicut factory.[122] It seems a fair offer, so Gama decides to personally finalize the arrangement.

January 5, 1503 – Vasco da Gama takes his cousin's ship, the Frol de la Mar, plus one caravel, to carry the Brahmin and the Nair back to Calicut, to finalize the peace treaty with the Zamorin. Gama leaves the rest of the 4th Armada in Cochin under D. Luis Coutinho. (Rumors of the imminent peace with Calicut angers the merchants of Cochin, who feel they will be short-changed by any agreement with Calicut; Coutinho has a difficult time securing the continued purchasing and loading of spices).

Gama is taking only a light escort, but he imagines Vicente Sodré is in the vicinity and will provide additional security. However, as it happens, Vicente Sodré had left Calicut a few days earlier. He had been maintaining a continuous blockade on Calicut harbor, and engaging in repeated cat-and-mouse chases with small Calicut fishing ships that dared venture out. At one point, Sodré gave a couple of fishing boats chase into a side-channel, and sailed into a trap – forty armed Calicut paraus quickly surrounded him. A lucky cannon shot on the lead ship broke up the ambush, allowing Sodré to extricate himself from there quickly. He sailed out and raced back to Cannanore to pick up the rest of his patrol.

Gama arrives in Calicut harbor during this absence, unaware of any of this. Seeing no sign of Sodré, Gama orders the escort caravel to go towards Cannanore to find him. He anchors his own ship, the large Flor de la Mar, inside the harbor and lowers a skiff to take the Brahmin to shore, to meet the Zamorin and arrange for the delivery of the compensation payment, retaining the Brahmin's two relatives and the Nair on board as hostages. Three days are spent waiting, the Brahmin shuttling back and forth between the ship and the shore repeatedly to report and consult on the progress of the negotiations.

All seemed to be going well, but in the early morning hours of the fourth day, however, a hundred armed zambuks and paraus swarm into the harbor from the nearby channels and quickly surround the Flor de la Mar.[123] The Flor's high sides do not allow the Portuguese to respond with artillery – the ship's cannons are mounted too high and the paraus are too close for an angle of shot, so the crew turns desperately to crossbows, musket fire and heaving rocks to keep them at bay. Days before the encounter, Gama had captured a large parau, which was now tied to the stern of the Flor. In the heat of the fighting, Malabari sappers row up to the tied parau, fill it with tinder, set it afire, and direct the flaming ship towards the Flor. Gama immediately orders the cables cut and the flames of the drifting parau only just miss them. Throughout all this, some of the Portuguese sailors are desperately trying to cut the cables on the anchor – a process that took time, as Gama had ordered it down with an iron chain. But eventually the anchor is cut, and the Flor begins to sail away. As distance is gained from the zambuks and paraus, the ship's cannons can now come into play and fire on the pursuers. The Flor reaches the mouth of the harbor just as Vicente Sodré arrives back from Cannanore with three caravels. Seeing the ambush is foiled, the Calicut boats turn around and slip back into the side-channels of the harbor.

It is a narrow escape. Before leaving Calicut, Gama orders the three hostages – the son & nephew of the Brahmin and the Nair – strung up by their necks on the main mast, in full view of the city of Calicut.[124] He dispatches their corpses on a raft to the shore, pinned with a note swearing revenge on the Zamorin.

After the ambush, Gama, escorted by Sodré's patrol returns to Cochin. Although the Portuguese were aware that the Zamorin had ordered his Malabari vassals to assemble an armada in Calicut, Gama seems to have been confident that the coastal patrol was keeping a lid on it, perhaps not quite realizing that smaller ships throughout the region could make their way to Calicut unmolested via the Kerala backwaters.

Late January, 1503 – The Trimumpara Raja of Cochin adds some more disturbing intelligence: the Zamorin has hired the services of a Red Sea Arab privateer 'Cojambar' (Khoja Ambar), and several large ships have slipped past the Portuguese blockade and were now in Calicut, joining the fighting fleet under the command of Calicut admiral 'Coja Casem' (Khoja Kassein). The assembled Calicut fleet is estimated at 20 large ships, 40 gun-mounted sambuks (large dhows) and an innumerable number of smaller oar-powered paraus, carrying several thousand armed men. Although a large Calicut fleet had failed against the much smaller 3rd Armada of João da Nova the previous year, the Zamorin might have calculated that the addition of the large ships and more experienced captains might tip the balance – particularly against the heavily loaded and less-maneuverable large naus of the 4th Armada.

The Trimumpara Raja of Cochin urges Gama to avoid the fleet and just set sail for Portugal at once. But Vasco da Gama refuses to revise his plans. He needs to return to Cannanore to deposit the factor Barbosa there and pick up a cargo of ginger he had ordered. And he was itching for revenge for the ambush.

Early February, 1503, After a final audience with Raja Trimumpara, taking aboard his ambassador to the Lisbon court, leaving Diogo Fernandes Correia as factor in Cochin, and taking Cabral's old factor Gonçalo Gil Barbosa, to serve as factor in Cannanore, Gama's fleet (around ten fully laden ships) finally leaves Cochin. They are soon joined by Sodré's caravel squadron, and set sail warily towards Cannanore, guns ready for the Calicut ambush.

Gama and Sodré spot the Calicut fleet of Coja Casem and Arab privateer Cojambar, near the coast, out of Calicut harbor. In one of the first recorded instances of a naval line of battle, Gama's spice naus and escort caravels sail in a line end-to-end, concentrating all their immense firepower as they pass against the twenty large Arab ships of Cojambar, before they can get organized, sinking a number of them and doing immense damage to the remainder. Although the Arab squadron is out of commission too soon, Coja Casem nonetheless proceeds forward with his fleet of Malabari sambuks, hoping to use their speed to outmaneuver the guns of the heavy-laden naus and reach for the grapple. But Gama sends the escort caravels under Vicente Sodré to intercept them in their tracks, while the cargo naus hurry on toward Cannanore. Although the caravels are outnumbered, it is not much of a battle. The fight is essentially over when Pero Rafael and Gil Matoso quickly board and capture Coja Casem's flagship (oddly, found with a lot of women and children on board). The Calicut fleet breaks up and rushes back to port. The pursuing caravels capture a number of sambuks, which they proceed to tow and set on fire before Calicut. The long-prepared ambush has been foiled. Danger dispelled, the caravels proceed to Cannanore to make junction with the main fleet.

The Battle of Calicut, like the previous year's naval battle of Cannanore, once again demonstrated the critical importance of the technical superiority of Portuguese ships and naval artillery. But it also demonstrated to the Portuguese that the Zamorin of Calicut was not as easy to intimidate as they had expected. Despite the terror actions, the bombardment and the naval blockade, the Zamorin steadfastly refused to capitulate to Vasco da Gama's terms. On the contrary, the hiring of an Arab privateer fleet demonstrated a certain resourcefulness and willingness to continue fighting and take the fight to the Portuguese.

The hiring of Cojambar was also a foreboding. The Zamorin clearly understood he had to appeal to foreigners to help close the technical gap between Indian and Portuguese forces. Surely it would only be a matter of time before the Zamorin got his hands on Arab, Turkish and Venetian technology, and more substantial support from these great powers than just a Red Sea pirate or two?

If the battle of Calicut impressed something on Vasco da Gama, it was precisely that the Portuguese in India were living on borrowed time, that it was going to take more resources than he had to bring the Zamorin to heel and secure continued Portuguese access to the spice markets. And that was the message he would bring back to Lisbon.

In the meantime, his priority was to do everything he could to maintain the Portuguese toe in India - that is, to protect the Portuguese factories and Indian allies of Cochin and Cannanore, from the Zamorin's inevitable revenge the moment the 4th Armada left.

Arriving in Cannanore, Gama leaves Cabral's old factor Gonçalo Gil Barbosa, and two assistants, Bastião Álvares and Diogo Nunes. With the permission of the Kolithiri Raja of Cannanore, Gama erects a small palisade around the factory. Some 200 armed men (others report merely 20) are to remain with the factory.

More troubling, however, is the India patrol squadron. Back in Lisbon, Vicente Sodré had been given a commission (regimento) by king Manuel I of Portugal instructing him to lead a patrol of five or six caravels in the Gulf of Aden, and prey on the rich Arab prizes going in and out of the Red Sea. But Vasco da Gama, realizing the vulnerability of Cochin and Cannanore, invokes rank as captain-major of the armada and orders Sodré to set that mission aside, and maintain his patrol on the Indian coast, to defend the Portuguese factories and their Indian allies against any reaction by the Zamorin.

March, 1503 – As soon as Vasco da Gama's 4th Armada leaves India, as predicted, Raja Trimumpara of Cochin receives intelligence that the Zamorin of Calicut is at this very moment preparing a landward invasion of Cochin. Portuguese factor Diogo Fernandes Correia urges Vicente Sodré to keep the caravel patrol squadron close to Cochin. But Vicente Sodré, eager for the easy plunder of the Arab Red Sea shipping, dismisses the rumors, Correia reminds him of Gama's orders, to no avail – Sodré pulls out his old royal regimento and orders the coastal patrol to follow him out to the Red Sea.[125] It is said that at least two of the captains of the coastal patrol refuse Sodré's orders, and willingly surrender the command of their ships rather than disobey Gama's original orders.

The composition of the patrol that set out to the Red Sea varies in different accounts. One arrangement[126] is that it was six ships: 1. Vicente Sodré, 2. Brás Sodré, 3. Pêro de Ataíde, 4. Pêro Rafael, 5. Diogo Pires, 6. Fernão Rodrigues Bardaças.

Vicente Sodré first sets out north to Gujarat, where it captures a great merchant ship off Chaul.[127] The patrol then sails west into the Gulf of Aden, at the mouth of the Red Sea, to catch more prizes.[128] About five Arab merchant ships are seized by the patrol there but, according to the account written later by Pêro de Ataíde,[129] the Sodré brothers set about claiming a disproportionate share of the plunder for themselves, including embezzling the royal fifth. In Ataíde's account, Brás Sodré appears as the villain of the story.[130] Already unhappy at the decision to abandon their comrades in India, the patrol captains quarreled with the Sodré brothers and nearly mutinied.

In late April, the patrol anchored in at Kuria Muria islands (off the coast of Oman). The local inhabitants warned them that a seasonal tempest was forming and that they had better move their ships to a safer shelter on the southern side of the island. Four patrol captains moved their ships accordingly, but Vicente Sodré and Brás Sodré refused (the ongoing quarrel over the spoils may have been a factor in this decision.) As the locals predicted, the tempest came, destroyed and sunk the ships of Vicente Sodré and Brás Sodré. Vicente went down with his ship, Brás survived to make it ashore, although he would die soon after in mysterious circumstances [131] The wreck site of the ships was discovered in May 1998 by Blue Water Recoveries Ltd (BWR) and archaeologically excavated in a series of subsequent expeditions in the years 2013, 2014 and 2015 jointly conducted and managed by David L. Mearns of BWR and Oman's Ministry of Heritage and Culture. The findings and conclusions of the project were made public by the MHC in a press conference in Muscat on 15 March 2016, on the same date that a project specific website[132] was launched and an interim report by Mearns, Parham and Frohlich was published in the International Journal of Nautical Archaeology.[133]

In the aftermath, the four remaining ships of the coastal patrol, who elected of Pêro de Ataíde as their new commander, set back for India. However, contrary winds make it a difficult journey, and they inch back only painfully and slowly. The battered patrol hobbles into Angediva island sometime in the summer of 1503, where they are forced to stop to repair their crippled ships. Four days after arriving in Angediva, a fifth ship, the caravel of António do Campo (who having missed the previous year's monsoon, was forced to stay in East Africa throughout all this) arrives in Anjediva and joins the patrol.[134] They are still repairing at Angediva when the ships of Francisco de Albuquerque and Nicolau Coelho, the vanguard of the 5th Armada, arrives in India in August, 1503.

April 1503 – Not long after the Sodré patrol departed for the Red Sea, the Zamorin of Calicut arrived with his 50,000-strong army at Repelim (Edapalli), on the boundaries of the Cochinese state. He demanded that the Raja Trimumpara of Cochin hand his Portuguese guests over to him. But Trimumpara refused and his son Narayan repels two Calicut assaults. By bribery and deceit, the Zamorin manages to detach a lot of Cochin's army, overwhelms the defenses and kills prince Narayan at a battle near the Edapalli ford. The Trimumpara Raja and his Portuguese guests (factor Diogo Fernandes Correia and his assistants), accompanied by a small loyal Nair guard, abandon Cochin city and flee across the harbor to Vypin, a barrier island of the Vembanad lagoon. Vypin's natural defenses and the deteriorating weather prevent the Zamorin from launching assault boats and seizing the island. Frustrated, the Zamorin burns down the city of Cochin. The siege will drag on for several months, until Francisco de Albuquerque, leading the remnant of the Sodré patrol, hurrying down from Angediva, arrived in Cochin in August–September, and forced the Calicut forces to withdraw.

Sometime during the course of this siege, the two Italian military engineers (and probable Venetian agents) that had come as passengers on Gama's ships - known only as João Maria (Gianmaria) and Pêro António (Pierantonio) – escaped Cochin and made their way to the Zamorin' camp, offering their services to the army of Calicut.[135] Expert gun-founders, the Italians will teach Calicut to found large European guns and help close the technological gap between Indian and Portuguese artillery.

The Zamorin of Calicut, before burning down Cochin, removed an ancient sacred stone, upon which the ancient Kings of Malabar (see Chera Dynasty) were traditionally ceremonially esconsed as lords of the sea and overlords of all the Malabari states. The sacred stone had originally been housed at the ancient Malabari capital of Cranganore, but had since been moved to Cochin. The Zamorin now moved it once more, to Edapalli.[136]
