to return to England, his lands were confiscated in March 1326. In September, Isabella and Mortimer invaded England with mercenary soldiers, and Edmund took part in the invasion. The invasion won the support of a great part of the English nobility, including Edmund's brother Thomas, and Henry, Earl of Lancaster, Thomas of Lancaster's brother. Edmund took part in the trials of the two Despensers, and in the council transferring power to Prince Edward, who was crowned King Edward III. For his participation in the coup, Edmund received a reward of land belonging to the Despensers, and the Earl of Arundel, who was also executed as a supporter of Edward II.
