In 1522, the Habsburg force under Georg Schenck van Toutenburg resumed the offensive and pushed the Guelders forces the following year out of Frisia. Furthermore, the Frisians rebels, whose charismatic leader Pier Gerlofs Donia had died from illness in 1520, were also defeated. Their leader Wijerd Jelckama and what was left of the Frisian army were captured in 1523, taken to the city of Leeuwarden and publicly beheaded. Jancko Douwama was also taken prisoner and died in captivity in Vilvoorde.By December 1524, Frisia was firmly in the hands of the Habsburg. It was renamed into the Lordship of Frisia and ruled by a Stadtholder. Henry of the Palatinate, the new Prince-Bishop of Utrecht, was in conflict with his own Utrecht citizens, who invited troops from Guelders to occupy the city. Henry had no choice but to ask Charles of Habsburg for help. The States of Overijssel also asked Charles to liberate their lands from Guelders. Charles of Habsburg demanded a price, namely that they recognized him as Lord, to which they agreed.Schenck van Toutenburg moved his army into Overijssel and Utrecht and easily chased the Guelders troops, who had already become very unpopular amongst the population. On October 20, 1528, Bishop Henry handed over power to Charles of Habsburg. The Bishopric of Utrecht came to an end and was divided into the Lordship of Utrecht and the Lordship of Overijssel, both ruled by a Habsburg Stadtholder. A daring raid through Holland, culminating in the sack of The Hague by Maarten van Rossum, Field Marshal of Guelders, didn't prevent Schenk van Toutenburg to attack some cities in Guelders, after which Charles of Guelders agreed to sign the Treaty of Gorinchem on October 3, 1528.
