Even with Lancaster defeated, the battle against the rebels was not over. Edmund was charged with overtaking Wallingford Castle from Maurice de Berkeley in January 1323, a task which he fulfilled with great success. For his loyalty, Edmund was rewarded with substantial holdings in Wales, primarily land forfeited by Roger Mortimer. The greater part of the spoils of war, however, went to the Despensers, who both benefited greatly from the forfeiture of the rebels. By 1326, the Despensers, father and son respectively, enjoyed incomes of £3,800 and £7,000, while Edmund's annual income was at only 2,355 marks (£1,570).
