 When "Vianen" finally departed Batavia again on 20 January, the monsoon had set in, preventing her from taking the usual route through the Sunda Strait.Instead, the captain, Gerrit Frederikszoon de Witt, was ordered to set a course through the Strait of Balamboan.Strong head winds then drove "Vianen" so far south that she ran aground in the vicinity of Barrow Island on the northwest coast of Australia.
