Edmund Beaufort (c. 1438 – 6 May 1471), styled 4th
Duke of Somerset, 6th Earl of Somerset, 3rd Marquess of Dorset, 3rd Earl of Dorset,[1] was an English nobleman, and a military commander during the
Wars of the Roses, in which he supported the
Lancastrian king
Henry VI.[a]
After the defeat of the Lancastrians in 1461, Edmund was brought up in
France with his younger brother
John Beaufort, Marquess of Dorset, and on the execution of his elder brother
Henry Beaufort, 3rd Duke of Somerset after the Battle of Hexham in 1464, Edmund is said to have succeeded as 4th Duke of Somerset by Lancastrians in February 1471, though his brother's attainder was never reversed, and his titles remained forfeit. In a proclamation dated 27 April 1471 Edmund is spoken of as "Edmund Beaufort, calling himself duke of Somerset".[6]
In October 1470 Beaufort returned from France when
King Edward IV was driven from the throne[6] after
Richard Neville, 16th Earl of Warwick's defection and alliance with
Queen Margaret and the
restoration of
King Henry VI, who was the first monarch ousted by the family feud, and whom due to occasional insanity she assisted in his duties, Somerset was unenthusiastic over the reconciliation and made little effort to co-operate. In fact his failure to hold London against Edward IV was a decisive moment, leading to the
Battle of Barnet (14 April 1471) and the death of Warwick. Some sources say he was present at Barnet, but this is an error.[8]
Fleeing west towards
Wales to seek help from
Jasper Tudor, but halted by the
Yorkist army at the
Battle of Tewkesbury (4 May 1471),[9] he commanded the van of the Lancastrian army at the battle. His position was almost unassailable,[10][11] but under the pressure of Edward's Flemish handgunners, once the battle began Beaufort moved down from the heights and attacked Edward IV's right flank. He was assailed by both the king and
Richard, Duke of Gloucester, and was soon put to flight, his conduct having practically decided the battle in favour of the Yorkists.[12]
After the defeat, Somerset and other Lancastrian leaders took refuge in
Tewkesbury Abbey, but they were forced from sanctuary two days later. They were tried and executed immediately, at the Cross in the centre of
Tewkesbury,[13] on Monday 6 May 1471.[6] He was buried on the south side of Tewkesbury Abbey, under an arch.[14] His younger brother John had been killed during the battle, and as both died unmarried, "the house of Beaufort and all the honours to which they were entitled became extinct".[6]
^Henry Beaufort, 3rd Duke of Somerset, was
attainted by Parliament on 4 November 1461, and most of his lands were granted to
King Edward IV's brother
Richard, Duke of Gloucester, and other Yorkists.[2] Henry Beaufort received a general pardon on 10 March 1463,[3] but after his execution Parliament annulled the act restoring him to his dignities, which again became forfeit and were not restored.[4] So although Edmund Beaufort was styled by supporters of the House of Lancaster as 4th Duke of Somerset, by act of Parliament he had no legitimate right to use the title. In 1485, some twenty-one years after the execution of the 3rd Duke of Somerset, Edmund Beaufort, along with
Jasper Tudor, had all acts of attainder against his father annulled in the first Parliament of
King Henry VII, "for their true and faithfull Allegeaunces and Services doune to the said blessed
King Herrie [VI]."[5]
