On 17 September, the five ships under the orders of Admiral van Warwyck came into view of Mauritius. On 20 September, they entered a sheltered bay which they named "Port de Warwick" (now known as "Grand Port"). They landed and decided to name the island "Prins Mauritz van Nassaueiland," after the son of William the Silent, Prince Maurits (Latin version: Mauritius) of the House of Nassau, the stadtholder of most of the Dutch Republic, and after the main vessel of the fleet, the "Mauritius".
