In 1512 the forces of Guelders under Duke Charles of Egmond occupied Anholt, as the Bronckhorst counts had sided with his rival Philip I of Castile, and could not be induced to release it until in 1537 they were paid a significant ransom.
William intervened in favor of Edward in the catastrophic war of succession between his brothers-in-law Reinald and Edward for control of the Duchy of Guelders.
The Lordship bordered three larger states: the Duchy of Guelders, the Bishopric of Münster, and the Duchy of Cleves.
It had been agreed that any sons they might have would have no right to the duchy of Guelders.
