Willem van Nassau

Willem van Nassau was born in 1595 and died at Groenlo on 18 August 1627. He was lord van der Leck (illegitimate son of Prince Maurits of Nassau). He was an infantry officer who commanded in a joint English-Dutch expedition to Spain. He commanded the blockade of Dunkirk from 1626 to 1627. He was killed in the siege of Groenlo. He was appointed as Lieutenant-Admiral of Holland and West-Friesland on 18 June 1625. The source for this is my translation of the entry in Luc Eekhout's Het Admiralenboek.
