 His handling of relations with the natives of Formosa too was a cause for concern , with the residents of Sinkan contrasting his harsh treatment with the " generous hospitality of the Japanese " . Nuyts had a low opinion of the natives , writing that they were " a simple , ignorant people , who know neither good nor evil " . In 1629 he narrowly escaped death when after being feted at the aboriginal village of Mattau , the locals took advantage of the relaxed and convivial atmosphere to slaughter sixty off @-@ guard Dutch soldiers — Nuyts was spared by having left early to return to Zeelandia . This incident was later used as a justification for the Pacification Campaign of 1635 – 36 .
