In this state of adversity, Badur at length consented to the erection of a fort at Diu by the Portuguese. He had formerly given up Basseen to them, to secure their friendship during his contest with Humayun, and was now in hopes by their assistance to recover his dominions. Still however his pride prompted him to temporize, and he sent an ambassador to request assistance from the Turks to recover his territories. Hearing that Humayun had taken Champaneer he gave himself up to despair and resolved upon going to Mecca, to wait the answer of the grand Turk; but his mother and friends dissuaded him, advising him to allow the Portuguese to erect the fort at Diu, as by their aid his affairs might be restored. He immediately sent notice to that effect to Martin Alfonso de Sousa, then at Chaul, who communicated the event to Nuno de Cuna, and went immediately to Diu at the request of Badur, arriving on the 21st of September 1536. A league offensive and defensive was immediately entered into between Badur and the Portuguese, in which the former treaty was confirmed, except that the emporium of trade was to be transferred from Basseen to Diu: The fort was to be built where and in what manner should be judged best by the governor-general; and in the mean time a bulwark or castle upon the sea, commanding the entrance of the port was to be delivered up. There were many other articles, and among these that the Portuguese were not to meddle with the kings revenues at Diu and other places. The governor general on receiving notice of this treaty, came immediately to Diu, where he was honourably received by Badur.
