 Robert Ferrers , Earl of Derby , was singled out in particular for his central involvement in the rebellion , and for him the multiple was seven rather than five . The same was the case for Henry de Hastings , who was the commander of Kenilworth Castle . Those who had not taken part in the fighting themselves , but had incited others to rise up against the king , were fined at two year 's value , while those who had been compelled to fight , or played only a minor part , had to pay one year 's value of their land . The proceedings from the fines were awarded to royal supporters , some of whom had already been awarded parts of the rebels ' land , and now had to give it back .
