In prison at Gorkum (from 26 June to 6 July 1572), the first 15 prisoners were transferred to Brielle, arriving there on 8 July. On their way to Dordrecht they were exhibited for money to the curious. The following day, William de la Marck, Lord of Lumey, commander of the "Gueux de mer", had them interrogated and ordered a disputation. In the meantime, four others arrived. It was demanded of each that he abandon his belief in the Transubstantiation, the doctrine of the real presence of Christ in the Blessed Sacrament, as well as the belief in the Papal supremacy. All remained firm in their faith. Meanwhile, there came a letter from the Prince of Orange, William the Silent, which enjoined all those in authority to leave priests and religious unmolested. Despite this call, on 9 July, they were hanged in a turfshed.
