Sebastian Gonzales Tibao/Tibeau, a salt-dealer who had come to Bengal in 1605, had escaped Arakanese punishment in Dianga with some other Portuguese captives and began a life of piracy which consisted of robbing the Arakan port and keeping their merchandise with their native allies in Bakla, or as some sources say Bhatkal. In March 1609, Fateh Khan dispatched a fleet to suppress these pirates who had been located in nearby South Shahbazpur. In retaliation, Tibao led 400 Portuguese mercenaries in a plan to colonise Sandwip. Tibao negotiated a deal with the King of Bakla or Bhatkal, receiving support such as ships and 200 horses for the takeover, in exchange for half of the revenue of the island to be given to Bakla's king. However, Tibao withheld the agreed payment and later warred with the King of Bakla too. A great battle took place in Sandwip, and it was only resolved after a Spanish ship of 50 men arrived at the island to help the Portuguese take over the Sandwip Fort. Fateh Khan, 3000 Muslim pirates and all of the island's male Muslim inhabitants were killed, allowing Tibao to become the ruler of Sandwip.
