Together with the republican-minded brothers Cornelis and Andries de Graeff and their cousins Cornelis and Andries Bicker, De Witt supported the Peace of Münster. In May 1650 they proposed to reduce the size of the army, which was opposed by William as commander of the army.
This dispute led to a coup by William, who tried to seize Amsterdam. On 30 June 1650, William arrested De Witt and the burgomasters of Delft, Hoorn, Medemblik, Haarlem, and Dordrecht at the Binnenhof in The Hague. They were imprisoned in Castle Loevestein. On 17 August they were released after having reversed the reduction of the army size.
