April 1503 – Not long after the Sodré patrol departed for the Red Sea, the Zamorin of Calicut arrived with his 50,000-strong army at Repelim (Edapalli), on the boundaries of the Cochinese state. He demanded that the Raja Trimumpara of Cochin hand his Portuguese guests over to him. But Trimumpara refused and his son Narayan repels two Calicut assaults. By bribery and deceit, the Zamorin manages to detach a lot of Cochin's army, overwhelms the defenses and kills prince Narayan at a battle near the Edapalli ford. The Trimumpara Raja and his Portuguese guests (factor Diogo Fernandes Correia and his assistants), accompanied by a small loyal Nair guard, abandon Cochin city and flee across the harbor to Vypin, a barrier island of the Vembanad lagoon. Vypin's natural defenses and the deteriorating weather prevent the Zamorin from launching assault boats and seizing the island. Frustrated, the Zamorin burns down the city of Cochin. The siege will drag on for several months, until Francisco de Albuquerque, leading the remnant of the Sodré patrol, hurrying down from Angediva, arrived in Cochin in August–September, and forced the Calicut forces to withdraw.
