Under new king Manuel I of Portugal, on July 1497 a small exploratory fleet of four ships and about 170 men left Lisbon under the command of Vasco da Gama. By December the fleet passed the Great Fish River—where Dias had turned back—and sailed into unknown waters. On 20 May 1498, they arrived at Calicut. The efforts of Vasco da Gama to get favorable trading conditions were hampered by the low value of their goods, compared with the valuable goods traded there. Two years and two days after departure, Gama and a survivor crew of 55 men returned in glory to Portugal as the first ships to sail directly from Europe to India.
