Charles de Lannoy kept Francis I in his custody and imprisoned him in a tower of Pizzighettone. The king was then brought to Genoa and from there he was taken to Spain. He remained jailed in a tower in Madrid until the Treaty of Madrid was signed. According to the treaty, Francis I abandoned its claims over Flanders, Milan and Burgundy. However, the peace treaty was broken in the same year and a new French-Imperial war lasted from 1526 to 1529.
