In the year 1537, Badur became still more intent upon removing the Portuguese from Diu, for which purpose he again sent to procure assistance from the Turks, and in the mean time used his utmost endeavours to take the fort and to destroy Nuno de Cuna, whom he invited to Diu with that view. Though apprized of the treacherous designs of Badur, De Cuna omitted to avail himself of an opportunity of securing him while on a visit on board his ship, deferring it to a future opportunity in a proposed conference in the fort. While Badur was going on shore in his _katur_ or barge, Emanuel de Sousa the commandant of the fort of Diu followed him in a barge and went on board the royal katur to give the invitation from the governor-general. At this time another Portuguese barge coming up hastily, Badur became suspicious of some evil intention, and ordered his officers to kill De Sousa. One Diega de Mosquita who had aided Badur in the late war and had acquired a perfect knowledge of the language, understood what was said by Badur, whom he immediately attacked and wounded, but De Sousa was slain by his attendants. Upon this a bloody affray took place between the Portuguese and the attendants on Badur, in which seven of the latter were slain. Several other boats belonging to both parties came up, and Badur attempted to escape in his barge to the city, but was stopped by a cannon-shot which killed three of his rowers; on which he endeavoured to escape by swimming, but being in danger of drowning he called out, discovering who he was. Tristan de Payva reached out an oar for him to take hold of, that he might get on board the boat; but a soldier struck him on the face with a halberd, and then others, till he was slain. His body sunk, and neither it nor the body of De Sousa could afterwards be found for interment.
