Thomas of Woodstock was in command of a large campaign in northern France that followed the War of the Breton Succession of 1343–64. The earlier conflict was marked by the efforts of John IV, Duke of Brittany to secure control of the Duchy of Brittany against his rival Charles of Blois. John was supported in this struggle by the armies of the Kingdom of England, whereas Charles was supported by the Kingdom of France. At the head of an English army, John prevailed after Charles was killed in battle in 1364, but the French continued to undermine his position, and he was later forced into exile in England. John returned to Brittany in 1379, supported by Breton barons who feared the annexation of Brittany by France. An English army was sent under Woodstock to support his position. Due to concerns about the safety of a longer shipping route to Brittany itself, the army was ferried instead to the English continental stronghold of Calais in July 1380. As Woodstock marched his 5,200 men east of Paris, they were confronted by the army of Philip the Bold, Duke of Burgundy, at Troyes, but the French had learned from the Battle of Crécy in 1346 and the Battle of Poitiers in 1356 not to offer a pitched battle to the English. Eventually, the two armies simply marched away. French defensive operations were then thrown into disarray by the death of King Charles V of France on 16 September 1380. Woodstock's chevauchée continued westwards largely unopposed, and in November 1380 he laid siege to Nantes and its vital bridge over the Loire towards Aquitaine. However, he found himself unable to form an effective stranglehold, and urgent plans were put in place for Sir Thomas Felton to bring 2,000 reinforcements from England. By January, though, it had become apparent that the Duke of Brittany was reconciled to the new French king Charles VI, and with the alliance collapsing and dysentery ravaging his men, Woodstock abandoned the siege.
Thomas of Woodstock was the leader of the Lords Appellant, a group of powerful nobles whose ambition to wrest power from Thomas's nephew, King Richard II of England, culminated in a successful rebellion in 1388 that significantly weakened the king's power. Richard II managed to dispose of the Lords Appellant in 1397, and Thomas was imprisoned in Calais to await trial for treason. During that time he was murdered, probably by a group of men led by Thomas de Mowbray, 1st Duke of Norfolk, and the knight Sir Nicholas Colfox, presumably on behalf of Richard II. This caused an outcry among the nobility of England that is considered by many to have added to Richard's unpopularity. Thomas was buried in Westminster Abbey, first in the Chapel of Saint Edmund and Saint Thomas in October 1397, and two years later reburied in the Chapel of Saint Edward the Confessor. His wife was buried next to him.
Marriage and progeny
Thomas married Eleanor de Bohun, the elder daughter and co-heiress with her sister, Mary de Bohun, of their father Humphrey de Bohun, 7th Earl of Hereford. Thomas of Woodstock and his wife Eleanor had:
Joan, who married Gilbert Talbot, 5th Lord Talbot and died in childbirth
Isabel, a nun of the Order of Minoresses
Philippa, died young
As he was attainted as a traitor, his dukedom of Gloucester was forfeit. The title Earl of Buckingham was inherited by his son, who died in 1399 only two years after Thomas' own death. Thomas of Woodstock's eldest daughter, Anne, married into the powerful Stafford family, who were Earls of Stafford. Her son, Humphrey Stafford was created Duke of Buckingham in 1444 and also inherited part of the de Bohun estates. The other part of these estatesincluding the Earldom of Hereford, which had belonged to Mary de Bohun and had then become incorporated into the holdings of the House of Lancasterbecame a matter of contention in the latter 15th century.
In literature
Thomas of Woodstock's murder plays a prominent part in William Shakespeare's play Richard II, though he is dead at the time of the play's beginning.
He also is the subject of Thomas of Woodstock, another Elizabethan drama by an anonymous playwright. Because of its stylistic affinities to Shakespeare's play, it is also called Richard the Second Part One.
