After violence and failed diplomacy during earlier Portuguese contact with Calicut, King Manuel I prepared a heavily armed follow-up expedition. In January 1502, Vasco da Gama was given the title of admiral and command of a major fleet intended to force trading terms and punish opponents on the Malabar Coast.
Da Gama’s main squadron sailed in February 1502 as part of the larger “4th India Armada.” The voyage combined long-distance commerce with naval coercion, signaling that Portugal intended to use force to shape Indian Ocean trade routes.
In mid-June 1502, da Gama’s expedition reached Sofala, a key trading port linked to gold routes in southeast Africa. Stopping at Sofala helped the Portuguese gather supplies and intelligence and reinforced their effort to control strategic ports along the route to India.
In July 1502, da Gama confronted the ruler of Kilwa (in present-day Tanzania) and threatened bombardment unless Kilwa submitted. Kilwa agreed to Portuguese demands, showing how the expedition used intimidation to reshape political relationships along the East African coast.
While operating near Cannanore, da Gama’s fleet seized an Arabian ship carrying both cargo and hundreds of passengers. Later accounts describe the ship being burned with many passengers killed, but major reference works note the story is based on late, disputed reporting and may be exaggerated or partly legendary.
By October 1502, the armada reached Cannanore (Kannur), north of Calicut. Da Gama negotiated cooperation with Cannanore’s ruler—an enemy of Calicut’s Zamorin—helping Portugal build a network of local partners for trade and protection.
In late October 1502, da Gama sailed to Calicut (Kozhikode) to compel favorable trade terms and retaliate for earlier attacks on Portuguese interests. When negotiations failed, he bombarded the port and seized hostages, escalating the conflict into open warfare along the Malabar Coast.
In early November 1502, da Gama moved south to Cochin (Kochi), where the local ruler was hostile to Calicut. Da Gama concluded a new commercial agreement and supported the Portuguese factory (trading post), aiming to secure steady spice purchases through an allied port.
In early January 1503, da Gama’s fleet fought a naval action off Calicut against forces linked to the Zamorin and allied corsairs. The engagement highlighted Portugal’s reliance on ship-mounted cannon and organized formation fighting to overpower larger regional fleets.
Before departing India, da Gama ordered a small squadron to remain near the Malabar Coast to defend Portuguese factories and allied cities, especially Cochin and Cannanore. This decision was meant to turn earlier, temporary voyages into a more continuous Portuguese naval presence in the Indian Ocean.
On February 20, 1503, da Gama sailed from Cannanore and began the long voyage back to Portugal via East Africa. His return marked the end of the expedition’s direct operations, leaving local allies and the patrol squadron to face immediate retaliation risks.
Da Gama reached Portugal in 1503 (with accounts noting arrival in Lisbon in September and later reaching the Tagus in October). He reported that he had not forced the Zamorin of Calicut into submission and argued for stronger, permanent defenses to protect Cochin and Cannanore—pointing toward a shift from raiding voyages to sustained occupation and fortification.
