When Simon de Montfort returned to England, Henry, supported by Eleanor, remained in Paris where he seized the opportunity to reassert royal authority and began to issue royal orders independently of the barons. Henry finally returned to retake power in England in April 1260, where conflict was brewing between Richard de Clare's forces and those of Simon and Edward. Henry's brother Richard mediated between the parties and averted a military confrontation; Edward was reconciled with his father and Simon was put on trial for his actions against the King. Henry was unable to maintain his grip on power, and in October a coalition headed by Simon, Richard and Edward briefly seized back control; within months their baronial council had collapsed into chaos as well.
