He distinguished himself as a counsellor to King John II of Portugal and later in the wars against the Moors and in the conquest of Granada in 1492 . In 1503 he was appointed as the first governor and viceroy of the Portuguese State of India ( " Estado da Índia " ) . Almeida is credited with establishing Portuguese hegemony in the Indian Ocean , with his victory at the naval Battle of Diu in 1509 . Before Almeida could return to Portugal , he lost his life in 1510 . His son Lourenço de Almeida too was killed in the Battle of Chaul in 1508 . Exploits as soldier . As was customary for men in his social circle , he joined the military at a young age . In 1476 he took part in the Battle of Toro . Then he fought in conflicts in different parts of Morocco and in 1492 participated in the Christian conquest of Granada on the side of the Castilians . Mission to the east . In 1505 King Manuel I of Portugal appointed Almeida , then in his mid 50s , as the first viceroy of Portuguese India ( " Estado da Índia " ) . With an armada of 22 ships , including 14 carrack s and 6 caravel s , Almeida departed from Lisbon on March 25 , 1505 . The armada carried a crew of 1 , 500 soldiers . The flagship was the carrack São Rafael captained by Fernão Soares . The mission ' s primary aims were to bring the spice trade under Portuguese control , to construct forts along the east African and Indian coasts , to further Portuguese spice trade through alliances with local chieftains , besides constructing trading posts . African conquest . Almeida rounded the Cape of Good Hope and entered African coastal waters again at Sofala and the Island of Mozambique , whence they proceeded northwards to the coastal settlement of Kilwa . In July 1505 they employed 8 ships to attack and conquer the ca 4 , 000 strong population of this harbour town . Because of the good harbour that the town provided , sufficient for anchoring ships up to 500 tons , the Portuguese decided to build a fort here . For this purpose Pêro Ferreira and a crew of 80 soldiers remained in the town . In August 1505 the Portuguese arrived at Mombasa , a coastal port further north . The city with a population of about 10 , 000 was conquered in heavy combat against the troops of the local Arab sheik . The city was plundered and torched . The Portuguese were assisted in this attack by a Mombasa enemy , the Sultan of Melinde . The same month a caravel of Almeida ' s fleet captained by John ( " João " ) Homere captured Zanzibar island and claimed it for Portugal . Viceroy in India . On 25 March 1505 , Francisco de Almeida was appointed " Viceroy of India " , on the condition that he would set up four forts on the south western Indian coast : at Anjediva Island , Cannanore , Cochin and Quilon . Francisco de Almeida left Portugal with a fleet of 22 vessels with 1 , 500 men . On 13 September , Francisco de Almeida reached Anjadip Island , where he immediately started the construction of Fort Anjediva . On 23 October , he started , with the permission of the friendly ruler Kōlattiri , the building of St . Angelo Fort in Cannanore , leaving Lourenço de Brito in charge with 150 men and two ships . Francisco de Almeida then reached Cochin on 31 October 1505 , with only 8 vessels left . There he learnt that the Portuguese traders at Quilon had been killed . He decided to send his son Lourenço with 6 ships , who wantonly destroyed 27 Calicut vessels in the harbour of Quilon . Almeida took up residence in Cochin . He strengthened the Portuguese fortifications of Fort Manuel on Cochin . The Zamorin of Calicut prepared a large fleet of 200 ships to oppose the Portuguese , but in March 1506 his son Lourenço de Almeida intercepted Zamorin ' s fleet in a sea battle at the entrance to the harbour of Cannanore , the Battle of Cannanore and inflicted heavy loss . Hereupon Lourenço de Almeida explored the coastal waters southwards to Colombo , modern Sri Lanka . Meanwhile , the Zamorin succeeded in convincing the Kōlattiri of Cannanore of the true imperialistic motives of Portuguese in Kerala . The Kōlattiri was already annoyed and angered with the Portuguese for their violation of the safe conduct guaranteed to the ships of Muslim merchants of Cannanore . The Kōlattiri put up a common fight against the Portuguese besieging Fort St . Angelo at the Siege of Cannanore . In 1507 Almeida ' s mission was strengthened by the arrival of Tristão da Cunha ' s squadron . Afonso de Albuquerque ' s squadron had however split from that of Cunha off east Africa and was independently conquering territories to the west . In March 1508 , at the request of the Arab merchants of Calicut , an Egyptian fleet under the command of Amir Husain Al - Kurdi ( Mir Hussain ) of the Mameluk Egyptian attacked and defeated the Portuguese squadron under command of Lourenço de Almeida at Chaul in the Battle of Chaul . Lourenço de Almeida was killed in this battle and led to a temporary retreat by the Portuguese from the Indian waters . Afonso de Albuquerque arrived at Cannanore at the close of 1508 and immediately made known an hitherto secret commission he had received from the King empowering him as governor to supersede Almeida at his term as viceroy . Almeida , determined to avenge the death of his son and free the Portuguese prisoners made at Chaul , refused to recognize Albuquerque ' s credentials immediately , and later arrested him . In 1509 , Almeida become the first Portuguese to set sail in Bombay . He sought Meliqueaz , to whom he had written a menacing letter , and the Mameluk Mirocem , fiercely investing at the naval Battle of Diu on February 3 , 1509 commanding a fleet of 23 ships near the port of Diu . He inflicted a decisive defeat on a joint fleet from the Mamlûk Burji Sultanate of Egypt , the Ottoman Empire , the Zamorin of Calicut and the Sultan of Gujarat , with technical naval support from the Republic of Venice and the Republic of Ragusa ( Dubrovnik ) , that feared for its eastern trade links . His victory was decisive : the Ottomans and Egyptians left the Indian Ocean , enabling Portuguese trade monopoly over Indian waters for over 100 years , into the 17th century when it was ended by the Dutch and English . Albuquerque was released after three months ' confinement , on the arrival of the grand - marshal of Portugal with a large fleet , in November 1509 . Return and death . Almeida sailed for Portugal in December 1509 and reached Table Bay near the Cape of Good Hope , where the Garcia , Belém and Santa Cruz dropped anchor late February , 1510 , to replenish water . There they encountered the local indigenous people the Khoikhoi . It is here the Admiral committed his greatest sin , one which he would pay for with the lives of his men and his own . After friendly trade with the Khoikhoi some of the crew visited their nearby village where they tried to steal some of the locals ' cattle . Almeida allowed his captains Pedro and Jorge Barreto to return to the village on the morning of March 1 , 1510 . The village ' s cattle herd was raided with the loss of one man , while Almeida awaited his men some distance from the beach . As the flagship ' s master Diogo d ' Unhos moved the landing boats to the watering point , the Portuguese were left without a retreat . The Khoikhoi sensed the opportunity for an attack , during which Almeida and 64 of his men perished , including 11 of his captains . Almeida ' s body was recovered the same afternoon and buried on the shore front of the current Cape Town . Relatives and subjects . Almeida was the son of the 1st Count of Abrantes and one of a number of highly distinguished siblings including two bishops , an ambassador to the Holy See and the Portuguese head of the Order of Malta . His son , Lourenço , was killed in battle , but he was survived by a daughter , Leonor , who married Rodrigo de Melo , Count of Tentúgal , precursors of the Dukes of Cadaval . Ferdinand Magellan ( " Fernão de Magalhães " ) accompanied Almeida to the east , but was promoted to captain and only returned in 1512 after losing that commission .
