failed to impress. While Zamorin's officials wondered at why there was no gold or silver, the Muslim merchants who considered da Gama their rival suggested that the latter was only an ordinary pirate and not a royal ambassador. Vasco da Gama's request for permission to leave a factor behind him in charge of the merchandise he could not sell was turned down by the King, who insisted that da Gama pay customs duty – preferably in gold – like any other trader, which strained the relation between the two. Annoyed by this, da Gama carried a few Nairs and sixteen fishermen (mukkuva) off with him by force. Return Vasco da Gama left Calicut on 29 August 1498. Eager to set sail for home, he ignored the local knowledge of monsoon wind patterns that were still blowing onshore. The fleet initially inched north along the Indian coast, and then anchored in at Anjediva island for a spell. They finally struck out for their Indian Ocean crossing on 3 October 1498. But with the winter monsoon yet to set in, it was a harrowing journey. On the outgoing journey, sailing with the summer monsoon wind, da Gama's fleet crossed the Indian Ocean in only 23 days; now, on the return trip, sailing against the wind, it took 132 days. Da Gama saw land again only on 2 January 1499, passing before the coastal Somali city of Mogadishu, then under the influence of the Ajuran Empire in the Horn of Africa. The fleet did not make a stop, but passing before Mogadishu, the anonymous diarist of the expedition noted that it was a large city with houses of four or five storeys high and big palaces in its center and many mosques with cylindrical minarets. Da Gama's fleet finally arrived in Malindi on 7 January 1499, in a terrible state – approximately half of the crew had died during the crossing, and many of the rest were afflicted with scurvy. Not having enough crewmen left standing to manage three ships, da Gama ordered the São Rafael scuttled off the East African coast, and the crew re-distributed to the remaining two ships, the São Gabriel and the Berrio. Thereafter, the sailing was smoother. By early March, they had arrived in Mossel Bay, and crossed the Cape of Good Hope in the opposite direction on 20 March, reaching the west African coast by 25 April.
