Thomas Mortimer and Thomas Molineux: Radcot Bridge and the Appeal of 1397

The appeal for treason lodged against Sir Thomas Mortimer in the parliament of 1397 as well as the entire background to the event has been the subject of considerable confusion. Much of this confusion has been the result of poor communication within the historical community. The information has been available, but it has appeared in diverse places. Thus, the two most recent biographers of Richard II, Anthony Steel and Harold Hutchison, have each been puzzled by the appeal of Mortimer: “The reasons for his inclusion are not clear…”; “…a mysterious addition for which no satisfactory explanation has ever been offered.” Sir Charles Oman, however, offered an explanation over sixty years ago: “As a small supplementary addition to the appeals of the previous autumn, two noted supporters of Gloucester in 1387 were dealt with—Lord Cobham, and Sir Thomas Mortimer, who had murdered the constable of Chester at Radcot Bridge.” Oman was not quite accurate when he grouped Mortimer with Cobham. Although Sir Thomas was not included in the original bill of appeal, he was cited in the summary of the appeal and the subsequent processes of the autumn session of Richard II's last parliament; lord Cobham did not become involved until the parliament reassembled in the next year. Oman's explanation of the matter, however, is not vitiated by this error. It, therefore, deserves further investigation as a solution to the mystery of Mortimer's appeal.
