22nd August 1659
Dutch Indonesia, Batavia (Jakarta)
Hundreds of warships of different sizes, carrying firearms of varying calibres, poured out from the Strait of Malacca. All the ships flew the tricolour flag of the Dutch, with an emblem printed on the top left corner. It was the Navy of Batavia, a separate naval unit of the Dutch Republic.
Leading all these ships was His Highness Henry Casimir II himself. He was the Count of Nassau-Dietz and a stakeholder of Fierceland and Groningen in the Dutch Republic. His father was William Frederick, Prince of Nassau-Dietz and Count of Albertine Agnes of Nassau, making him the cousin of the current leader of the Dutch Republic, William III, through their shared parenthood under their ancestor William the Silent.
