The fleet left Lisbon on 6 April 1506. Afonso piloted his ship himself, having lost his appointed pilot on departure. In Mozambique Channel, they rescued Captain Joao da Nova, who had encountered difficulties on his return from India; da Nova and his ship, the Frol de la mar, joined da Cunha's fleet. From Malindi, da Cunha sent envoys to Ethiopia, which at the time was thought to be closer than it actually is. Those included the priest Joao Gomes, Joao Sanches and Tunisian Sid Mohammed who, having failed to cross the region, headed for Socotra; from there, Afonso managed to land them in Filuk. After successful attacks on Arab cities on the east Africa coast, they conquered Socotra and built a fortress at Suq, hoping to establish a base to stop the Red Sea commerce to the Indian Ocean. However, Socotra was abandoned four years later, as it was not advantageous as a base. At Socotra, they parted ways: Tristao da Cunha sailed for India, where he would relieve the Portuguese besieged at Cannanore, while Afonso took seven ships and 500 men to Ormuz in the Persian Gulf, one of the chief eastern centers of commerce. On his way, he conquered the cities of Curiati (Kuryat), Muscat in July 1507, and Khor Fakkan, accepting the submission of the cities of Kalhat and Sohar. He arrived at Ormuz on 25 September and soon captured the city, which agreed to become a tributary state of the Portuguese king. Hormuz was then a tributary state of Shah Ismail of Persia. In a famous episode, shortly after it's conquest Albuquerque was confronted by Persian envoys, who demanded the payment of the due tribute from him instead. He ordered them be given a stock of cannonballs, arrows and weapons, retorting that "such was the currency struck in Portugal to pay the tribute demanded from the dominions of King Manuel" According to Bras de Albuquerque, it was Shah Ismael who coined the term "Lion of the seas", addressing Albuquerque as such. Afonso began building the Fort of Our Lady of Victory (later renamed Fort of Our Lady of the Conception), engaging his men of all ranks in the work. However, some of his officers revolted against the heavy work and climate and, claiming that Afonso was exceeding his orders, departed for India. With the fleet reduced to two ships and left without supplies, he was unable to maintain this position for long. Forced to abandon Ormuz in January 1508, he raided coastal villages to resupply the settlement of Socotra, returned to Ormuz, and then headed to India. Afonso arrived at Cannanore on the Malabar coast in December 1508, where he opened before the viceroy, Dom Francisco de Almeida, the sealed letter which he had received from the King, and which named as governor to succeed Almeida. The viceroy, supported by the officers who had abandoned Afonso at Ormuz, had a matching royal order, but declined to yield, protesting that his term ended only in January and stating his intention to avenge his son's death by fighting the Mamluk fleet of Mirocem, refusing Afonso's offer to fight him himself. Afonso avoided confrontation, which could have led to civil war, and moved to Kochi, India, to await further instruction from the King, maintaining his entourage himself. He was described by Fernao Lopes de Castanheda as patiently enduring open opposition from the group that had gathered around Almeida, with whom he kept formal contact. Increasingly isolated, he wrote to Diogo Lopes de Sequeira, who arrived in India with a new fleet, but was ignored as Sequeira joined the Viceroy. At the same time, Afonso refused approaches from opponents of the Viceroy, who encouraged him to seize power. On 3 February 1509, Almeida fought the naval Battle of Diu against a joint fleet of Mamluks, Ottomans, the Zamorin of Calicut, and the Sultan of Gujarat, regarding it as personal revenge for the death of his son. His victory was decisive: the Ottomans and Mamluks abandoned the Indian Ocean, easing the way for Portuguese rule there for the next century. In August, after a petition from Afonso's former officers with the support of Diogo Lopes de Sequeira claiming him unfit for governance, Afonso was sent in custody to St. Angelo Fort in Cannanore. There he remained under what he considered to be imprisonment. In September 1509, Sequeira tried to establish contact with the Sultan of Malacca but failed, leaving behind 19 Portuguese prisoners. Afonso returned from Malacca to Cochin, but could not sail to Goa as it faced a serious revolt headed by the forces of Ismael Adil Shah, the Sultan of Bijapur, commanded by Rasul Khan and his countrymen. During Afonso's absence from Malacca, Portuguese who opposed the taking of Goa had waived its possession, even writing to the King that it would be best to let it go. Held up by the monsoon and with few forces available, Afonso had to wait for the arrival of reinforcement fleets headed by his nephew D. Garcia de Noronha, and Jorge de Mello Pereira. While at Cochin, Albuquerque started a school. In a private letter to King Manuel I, he states that he had found a chest full of books with which to teach the children of married Portuguese settlers (casados) and Christian converts to read and write which, according to Albuquerque, there were about a hundred in his time, "all very sharp and easily learn what they are taught". On 10 September 1512, Afonso sailed from Cochin to Goa with fourteen ships carrying 1,700 soldiers. Determined to recapture the fortress, he ordered trenches dug and a wall breached. But on the day of the planned final assault, Rasul Khan surrendered. Afonso demanded the fort be handed over with its artillery, ammunition and horses, and the deserters to be given up. Some had joined Rasul Khan when the Portuguese were forced to flee Goa in May 1510, others during the recent siege. Rasul Khan consented, on condition that their lives be spared. Afonso agreed and he left Goa. He did spare the lives of the deserters, but had them horribly mutilated. One such renegade was Fernao Lopes, bound for Portugal in custody, who escaped at the island of Saint Helena and led a 'Robinson Crusoe' life for many years. After such measures the town became the most prosperous Portuguese settlement in India.
