The diary record of the expedition ends abruptly here. Reconstructing from other sources, it seems they continued to Cape Verde, where Nicolau Coelho's Berrio separated from Vasco da Gama's São Gabriel and sailed on by itself. The Berrio arrived in Lisbon on 10 July 1499 and Nicolau Coelho personally delivered the news to King Manuel I and the royal court, then assembled in Sintra. In the meantime, back in Cape Verde, da Gama's brother, Paulo da Gama, had fallen grievously ill. Da Gama elected to stay by his side on Santiago island and handed the São Gabriel over to his clerk, João de Sá, to take home. The São Gabriel under Sá arrived in Lisbon sometime in late July or early August. Da Gama and his sickly brother eventually hitched a ride with a Guinea caravel returning to Portugal, but Paulo da Gama died en route. Da Gama disembarked at the Azores to bury his brother at the monastery of São Francisco in Angra do Heroismo, and lingered there for a little while in mourning. He eventually took passage on an Azorean caravel and finally arrived in Lisbon on 29 August 1499 (according to Barros), or early September (8th or 18th, according to other sources). Despite his melancholic mood, da Gama was given a hero's welcome and showered with honors, including a triumphal procession and public festivities. King Manuel wrote two letters in which he described da Gama's first voyage, in July and August 1499, soon after the return of the ships. Girolamo Sernigi also wrote three letters describing da Gama's first voyage soon after the return of the expedition. The expedition had exacted a large cost – two ships and over half the men had been lost. It had also failed in its principal mission of securing a commercial treaty with Calicut. Nonetheless, the small quantities of spices and other trade goods brought back on the remaining two ships demonstrated the potential of great profit for future trade. Vasco da Gama was justly celebrated for opening a direct sea route to Asia. His path would be followed up thereafter by yearly Portuguese India Armadas. The spice trade would prove to be a major asset to the Portuguese royal treasury, and other consequences soon followed. For example, da Gama's voyage had made it clear that the east coast of Africa, the Contra Costa, was essential to Portuguese interests; its ports
