To this end he ratified two treaties with the Dutch Admiral Cornelis Matelieff de Jonge in May and September 1606.[2] Following a crippling blockade of the Johor River in 1608 and 1609, he signed a peace agreement with the Portuguese in October 1610. His fate and death remain uncertain. Some claim that he fled Batu Sawar at the time of the Acehnese attack in 1613 and died in exile on Lingga while others claim that he had been captured twice by the Acehnese Acehnese between 1613 and 1615 and subsequently sentenced to death around 1615.
