Early campaigns Hostilities between the rival Yorkist and Lancastrian factions flared into armed conflict in 1455 with provocations directed against the Duke of York that are reckoned as the beginning of the
War of the Roses, in which Margaret asserted a decided role of leadership as the position of her husband deteriorated. In May, just over five months after Henry VI recovered from a bout of mental illness and Richard of York's protectorship had ended, Margaret and Henry called for a
Great Council from which the Yorkists were excluded. The Council called for an assemblage of the peers at
Leicester with the stated purpose to protect the king from his enemies. The Lancastrians suffered a crushing defeat at the
First Battle of St Albans on 22 May 1455. In March 1458, along with her husband and leading nobles of the warring factions, she took part in
The Love Day procession in
London. In 1459, hostilities resumed at the
Battle of Blore Heath, where
James Tuchet, 5th Baron Audley, was defeated and killed by the Yorkist army under the command of
Richard Neville, 5th Earl of Salisbury. In 1457, the kingdom was again shaken when it was discovered that
Pierre de Brézé, a powerful French general and an adherent of Margaret, had landed on the English coast and burnt the town of
Sandwich. As leader of a French force of 4,000 men from
Honfleur, he aimed at taking advantage of the chaos in England. The mayor, John Drury, was killed in this raid. It thereafter became an established tradition, which survives to this day, that the
Mayor of Sandwich wears a black robe mourning this ignoble deed. Margaret, in association with Brézé, became the object of scurrilous rumours and vulgar ballads. Public indignation was so high that Margaret, with great reluctance, was forced to give the Duke of York's kinsman
Richard Neville, 16th Earl of Warwick, a commission to keep the sea for three years. He already held the post of
Captain of Calais. While Margaret was attempting to raise further support for the Lancastrian cause in
Scotland, her principal commander,
Henry Beaufort, 3rd Duke of Somerset, gained a major victory for her at the
Battle of Wakefield on 30 December 1460 by defeating the combined armies of the Duke of York and the Earl of Salisbury. Both men were beheaded and their heads displayed on the gates of the city of York. As Margaret was in Scotland at the time of the battle, it was impossible that she issued the orders for their execution, despite popular belief to the contrary. Next was the
Second Battle of St Albans (at which she was present) on 17 February 1461.
Sojourn to France The Lancastrian army was beaten at the
Battle of Towton on 29 March 1461 by the son of the late Duke of York, the future
Edward IV of England, who deposed King Henry and proclaimed himself king. Margaret was determined to win back her son's inheritance and fled with him into Wales and later Scotland. Finding her way to France, she made an ally of her cousin, King
Louis XI of France, and at his instigation, she allowed an approach from Edward's former supporter, Richard Neville, Earl of Warwick, who had fallen out with his former friend as a result of Edward's marriage to
Elizabeth Woodville, and was now seeking revenge for the loss of his political influence. Warwick's daughter,
Anne Neville, was married to Margaret's son Edward, Prince of Wales, in order to cement the alliance, and Margaret insisted that Warwick return to England to prove himself before she followed. He did so,
restoring Henry VI briefly to the throne on 3 October 1470.
Final defeat at Tewkesbury By the time Margaret, her son and daughter-in-law Anne were ready to follow Warwick back to England, the tables had again turned in favour of the Yorkists, and the Earl was defeated and killed by the returning King Edward IV in the
Battle of Barnet on 14 April 1471. Margaret was forced to lead her own army at the
Battle of Tewkesbury on 4 May 1471, at which the Lancastrian forces were defeated and her seventeen-year-old son
Edward of Westminster was killed. The circumstances of Edward's death have never been made clear; it is not known whether he was killed in the actual fighting or executed after the battle by the
Duke of Clarence. Over the previous ten years, Margaret had gained a reputation for aggression and ruthlessness, but following her defeat at Tewkesbury and the death of her only son, she was completely broken in spirit. After she was taken captive by
William Stanley at the end of the battle, Margaret was imprisoned by the order of King Edward. It is said that Stanley informed Margaret of her son's death. Once she learned of this, she "had to be bodily dragged from the priory where she was hiding." She was sent first to
Wallingford Castle and then was transferred to the more secure
Tower of London. Henry VI was also imprisoned in the Tower in the wake of Tewkesbury and he died there on the night of 21 May; the cause of his death is unknown, though
regicide was suspected, specifically smothering in his sleep. In 1472 she was placed in the custody of her former lady-in-waiting
Alice Chaucer, Duchess of Suffolk, where she remained until ransomed by Louis XI of France in 1475. == Final years and death ==
