In 1294, Eric "Menved" in return ordered Grand's and Lange's arrestment. Grand was imprisoned in Søborg Castle in Northern Zealand under both humiliating and unhealthy conditions. After some months in terrible conditions, Eric "Menved" sent a messenger to Grand to see if he would swear allegiance again and promise to seek no revenge for his captivity. He replied: "Rather than bend to his will, I would rather that the king sliced me apart joint by joint than submit to his commands." Pope Celestine V protested Grand's imprisonment, but in vain. Lange was held in captivity in Kalundborg castle. At the beginning of 1295 Lange managed to escape and fled to Rome pleading the new Pope Boniface VIII for help.
