Georg built the Toutenburg in Vollenhove, where he had been appointed bailiff. He succeeded in pushing back the Guelders led by Christoffel, Count of Meurs. Jancko Douwama came into conflict with Schenck, but lost. Schenck captured Dokkum (see J. of Golstein), and ultimately Sloten and Lemmer. He took the war out of Friesland, fighting Charles, Duke of Guelders in the Guelders Wars, becoming stadholder of Overijssel, defeating the Anabaptists at Bloemkamp, and also capturing Groningen and Drenthe (1536) after the Battle of Heiligerlee, where he also became stadholder. Friesland's current administrative structures owe much to him. Under his administration the Protestants gained power, despite strict bans.
