The Minister of the Imperial Navy had to negotiate a settlement, I think she threatened to restart the conflict and carnage inland if she and the majority of her pirates were to peaceably withdraw and all charges dropped. In the deal, some pirates were laid blame and were detained and executed that were likely her political enemies. So the Minister blinked and caved to her terms to keep the peace. I think she knew her time has come to retire, she could take on the Imperial Navy but with the powerful Portuguese Warships allied with the Navy?
