"Maarten (Martin) Schenck van Nydeggen, (1540?, – 11 August 1589) was a noted military commander in the Netherlands.
He first served with William of Orange in the fight for Dutch independence from Spain then switched to serve with distinction in the Spanish army. In 1580 he changed his allegiance to the Dutch Republic and was declared Lord of Toutenburg in Gelderland, Knight and Marshall of the Camp by the Dutch States General.
He then served on the Protestant side in the Cologne War with some success until he drowned in the Waal in a failed attack on Nijmegen in 1588." - (en.wikipedia.org 20.05.2022)
