 The Sultan of Tidore, Gapi Baguna, had supported Babullah after the murder of Hairun, but grew increasingly uneasy with Ternate's power ambitions.He therefore sailed over to Ambon in 1576 to draw up a strategical alliance with the Portuguese.On his way back he was trapped by a Ternate fleet and captured, though he was liberated through a daring raid by his kinsman Kaicili Salama.
