Schenck van Toutenburg was unable to unite the Catholics under his archbishopric. Under his tenure, many good Catholic Utrecht burgers became secret Protestants. As the Dutch Revolt began and William the Silent, stadtholder since 1559, fled, Maximilien de Hénin-Liétard was named the official stadtholder of the Netherlands in 1567 with his base in Utrecht at Vredenburg (castle). Like Schenck van Toutenburg, he met with insurrection with those under his command. After unsuccessfully preventing the Capture of Brielle in April–June 1572, he convened a meeting of the States General in The Hague in July 1572, but many representatives convened a new meeting in Dordrecht later that month, in which they pledged allegiance to William the Silent (or now, William of Orange). As the country turned to Protestantism and the Orange sympathies grew, Hénin-Liétard was taken prisoner at the Battle on the Zuiderzee on 11 October 1573. His Spanish troops based at Vredenburg thus lost their local leader.
