  The follow-up expedition, the Second India Armada, launched in 1500 under the command of Pedro Álvares Cabral with the mission of making a treaty with the Zamorin of Calicut and setting up a Portuguese factory in the city. However, Pedro Cabral entered into a conflict with the local Arab merchant guilds, with the result that the Portuguese factory was overrun in a riot and up to 70 Portuguese were killed. Cabral blamed the Zamorin for the incident and bombarded the city. Thus war broke out between Portugal and Calicut.
  
  Vasco da Gama invoked his royal letter to take command of the Fourth India Armada, scheduled to set out in 1502, with the explicit aim of taking revenge upon the Zamorin and force him to submit to Portuguese terms. The heavily armed fleet of fifteen ships and eight hundred men left Lisbon on 12 February 1502. It was followed in April by another squadron of five ships led by his cousin, Estêvão da Gama (the son of Aires da Gama), which caught up to them in the Indian Ocean. The Fourth Armada was a veritable da Gama family affair. Two of his maternal uncles, Vicente Sodré and Brás Sodré, were pre-designated to command an Indian Ocean naval patrol, while brothers-in-law Álvaro de Ataíde (brother of Vasco's wife Catarina) and Lopo Mendes de Vasconcelos (betrothed to Teresa da Gama, Vasco's sister) captained ships in the main fleet.
  
  On the outgoing voyage, da Gama's fleet opened contact with the East African gold trading port of Sofala and reduced the sultanate of Kilwa to tribute, extracting a substantial sum of gold.
