At some point in the civil war, Braose, fighting for the king, had devastated young SImon’s Sussex manor of Sedgewick, one of Mansel’s former possessions. Simon had his revengge on 30 June 1264, probably in the final days of the parliament which had seen his father’s power confirmed. Summoned several times to the Tower to answer for his offence before a ‘court’ headed by Hugh Despenser, th ejusticiar, Henry de Montfort, and Henry de Hastings, Braose failed to appear. Damages were then awarded against him in the sum of 10,000 makrs, the outraeously high figure put on his losses by Simon; and Braose was told to pay this amount, or name pledges for payment, within ten days. In the meantime, Simon was to retain his enemy’s young heir and his Sussex castel and park at Knep, already in his hands by a prior agreement with Braose, until payment ofr pledges had been proffered.
