Question: On which date was this battle of the English Wars of the Roses fought after which William Bonville, 1st Baron Bonville was executed?

full_context: Document 1: Second Battle of St Albans: The Second Battle of St Albans was a battle of the English Wars of the Roses, fought on 17 February 1461, at St Albans. The army of the Yorkist faction under the Earl of Warwick attempted to bar the road to London north of the town. The rival Lancastrian army used a wide outflanking manoeuvre to take Warwick by surprise, cut him off from London, and drive his army from the field. The victors also released the feeble King Henry VI, who had been Warwick's prisoner, from his captivity. However, they ultimately failed to take advantage of their victory.
Document 2: Baron Bonville: The title of Baron Bonville was created once in the Peerage of England. On 23 September 1449, William Bonville was summoned to Parliament. On his death in 1461, the barony was inherited by his great-granddaughter Cecily Bonville, who two months before succeeded as Baroness Harington, with which title the barony merged until 1554, when both baronies were forfeited. From her death in 1529 to the forfeiture in 1554, the baronies were merged with the title of Marquess of Dorset.
Document 3: Richard Neville, 16th Earl of Warwick: Richard Neville, 16th Earl of Warwick (22 November 1428 – 14 April 1471), known as Warwick the Kingmaker, was an English nobleman, administrator, and military commander. The son of Richard Neville, 5th Earl of Salisbury, Warwick was the wealthiest and most powerful English peer of his age, with political connections that went beyond the country's borders. One of the leaders in the Wars of the Roses, originally on the Yorkist side but later switching to the Lancastrian side, he was instrumental in the deposition of two kings, a fact which later earned him his epithet of "Kingmaker" to later generations.
Document 4: Cecily Bonville, 7th Baroness Harington: Cecily Bonville, 7th Baroness Harington and 2nd Baroness Bonville (c. 30 June 1460 – 12 May 1529) was an English peer, who was also Marchioness of Dorset by her first marriage to Thomas Grey, 1st Marquess of Dorset, and Countess of Wiltshire by her second marriage to Henry Stafford, 1st Earl of Wiltshire.
Document 5: James Harrington (Yorkist knight): Sir James Harrington, KB, MP of Hornby (?1430 – 22 August 1485) was a prominent supporter of the House of York in Northern England during the Wars of the Roses, having been retained by Richard Neville, 5th Earl of Salisbury, who was brother-in-law to the head of the House of York, Richard of York. He was second son of Sir Thomas Harrington, who had died with the king's father at the Battle of Wakefield in December 1460. James himself had fought with Salisbury at the Battle of Blore Heath in 1459, where he had been captured and imprisoned by the Lancastrians until the next year. He was a significant regional figure during the reign of King Edward IV, although the early years of the new king's reign were mared by a bitter feud between him and the Stanley family over a castle in Lancashire. On the accession of King Richard III in 1485, he was appointed to the new king's Household, and as such was almost certainly with him at Battle of Bosworth two years later. It is likely that he fell in battle there, although precise details of his death are now unknown.
Document 6: Edmund Beaufort, 2nd Duke of Somerset: Edmund Beaufort, 2nd Duke of Somerset, KG (1406 – 22 May 1455), sometimes styled 1st Duke of Somerset, was an English nobleman and an important figure in the Wars of the Roses and in the Hundred Years' War. He also succeeded in the title of 4th Earl of Somerset and was created 1st Earl of Dorset and 1st Marquess of Dorset (previously held by his father and later forfeited), and Count of Mortain. He was known for his deadly rivalry with Richard Plantagenet, 3rd Duke of York.
Document 7: Thomas de Courtenay, 5th/13th Earl of Devon: Thomas Courtenay, 5th/13th Earl of Devon (1414–1458) was an English nobleman who was involved in the Wars of the Roses. His seat was Colcombe Castle, near Colyton, Devon, and later the principal historic family seat of Tiverton Castle after his mother's death. Much of his life was spent in armed territorial struggle against his near-neighbour in Devon Sir William Bonville of Shute, Devon, at a time when central control over the provinces was weak. He had been married off as an infant to Margaret Beaufort, granddaughter of John of Gaunt, Duke of Lancaster, and started his career an adherent to the Lancastrian Beaufort party. On the demise of the Beaufort party he abandoned it in favour of the Duke of York. When York sought the support of Courtenay's arch-enemy Bonville, Courtenay fell out of favour with York. The Wars of the Roses led to the deaths and executions of all three of his sons, successively 6th, 7th, and 8th Earls of Devon, and the eventual attainder of his titles and forfeiture of his lands. The Earldom was however revived in 1485 for his distant cousin Sir Edward Courtenay, KG, (d. 1509), third in descent from his great-uncle. The ordinal number given to the early Courtenay Earls of Devon depends on whether the earldom is deemed a new creation by the letters patent granted 22 February 1334/5 or whether it is deemed a restitution of the old dignity of the de Redvers family. Authorities differ in their opinions, and thus alternative ordinal numbers exist, given here.
Document 8: Battle of Hedgeley Moor: The Battle of Hedgeley Moor, 25 April 1464, was a battle of the Wars of the Roses. It was fought at Hedgeley Moor, north of the village of Glanton in Northumberland, between a Yorkist army led by John Neville, Lord Montagu and a Lancastrian army led by Henry Beaufort, Duke of Somerset. The battle ended in a Yorkist victory.
Document 9: Thomas Neville (died 1460): Sir Thomas Neville, (c. 1429–1460) was the second son of Richard Neville, 5th Earl of Salisbury, a major magnate in the north of England during the fifteenth-century Wars of the Roses, and a younger brother to the more famous Richard Neville, Earl of Warwick, known as the 'Kingmaker.' Thomas worked closely with them both in administering the region for the Crown, and became a significant player in the turbulent regional politics of Northern England in the early 1450s. His wedding in August 1453 marked the beginning of his family's armed feud with their rivals, the House of Percy, in which Thomas and his brother John led a series of raids, ambushes and skirmishe across Yorkshire against the Percys. Many historians describe the feud as the beginning of the Wars of the Roses, a series of dynastic struggles in mid-fifteenth century England, and Thomas Neville played a large role in his father's alliance with Thomas's uncle, Richard, 3rd Duke of York.
Document 10: Anne Boleyn: ( 1501 – 19 May 1536) was Queen of England from 1533 to 1536 as the second wife of King Henry VIII. Henry's marriage to her, and her subsequent execution by beheading, made her a key figure in the political and religious upheaval that was the start of the English Reformation.
Document 11: William Bonville, 6th Baron Harington: William Bonville, 6th Baron Harington (1442 –19 February 1461) was an English nobleman who was a loyal adherent of the House of York during the dynastic conflict in England in the 15th century known as the Wars of the Roses. He was executed following the Yorkist defeat at the Second Battle of St Albans, leaving his six-month-old daughter, Cecily Bonville heiress to his barony.
Document 12: Elizabeth Woodville: Elizabeth Woodville (also spelled Wydville, Wydeville, or Widvile; c. 1437 – 8 June 1492) was Queen consort of England as the spouse of King Edward IV from 1464 until his death in 1483. At the time of her birth, her family was mid-ranked in the English aristocracy. Her first marriage was to a minor supporter of the House of Lancaster, Sir John Grey of Groby; he died at the Second Battle of St Albans, leaving Elizabeth a widowed mother of two sons. Her second marriage, to Edward IV, was a cause célèbre of the day, thanks to Elizabeth's great beauty and lack of great estates. Edward was only the second king of England since the Norman Conquest to have married one of his subjects, and Elizabeth was the first such consort to be crowned queen. Her marriage greatly enriched her siblings and children, but their advancement incurred the hostility of Richard Neville, Earl of Warwick, 'The Kingmaker', and his various alliances with the most senior figures in the increasingly divided royal family.
Document 13: William Bonville, 1st Baron Bonville: William Bonville, 1st Baron Bonville (c. 1392/3 – 18 February 1461), KG, of Shute, Devon, was an English nobleman, soldier, and administrator. He was a staunch Yorkist during the Wars of the Roses, and was executed following the Lancastrian victory at the Second Battle of St Albans by order of King Henry VI's Queen Consort, Margaret of Anjou.
Document 14: Historie of the arrivall of Edward IV: The Historie of the Arrivall of Edward IV. in England and the Finall Recouerye of His Kingdomes from Henry VI. A.D. M.CCCC.LXXI is a chronicle from the period of the Wars of the Roses. As the title implies, the main focus of the work is Edward IV's arrival in England in 1471 to reclaim his crown. On 2 October 1470, King Edward had fled to Flanders in the face of a rebellion by Richard Neville, Earl of Warwick. Warwick set upas a puppet kingHenry VI, whom he had himself previously helped depose. On the continent Edward received support from Charles the Bold, Duke of Burgundy, and on 14 March 1471 he landed at Ravenspurn in Yorkshire, and started making his way south. On 14 April Edward defeated Warwick at the Battle of Barnet. Warwick was killed and Edward's reign was secured.
Document 15: John Clifford, 9th Baron Clifford: John Clifford, 9th Baron Clifford, (8 April 1435 – 28 March 1461), was a Lancastrian military leader during the Wars of the Roses. The Clifford family were one of the most prominent families among the northern English nobility of the fifteenth century; and by the marriages of his sisters John Clifford had links to some very important families of the time, including the earls of Devon. He was orphaned at about twenty years of age when his father was slain at the first battle of the Wars of the Roses, the Battle of St Albans in 1455. It was probably as a result of his father's death there that John became one of the strongest supporters of Queen Margaret of Anjou, consort of King Henry VI, who ended up as effective leader of the Lancastrian faction. John Clifford had already achieved prominence in the north where, as an ally of the son of the earl of Northumberland, he took part in a feud against the Neville family, the Percy's natural rivals in Yorkshire. This consisted of a series of armed raids, assaults and skirmishes, and included an ambush on one of the younger Nevilles' wedding party in 1453. Historians have seen a direct connection between his involvement in the local feud in the north with the Nevilles, and his involvement in the national struggle against the duke of York, whom the Nevilles were closely allied with in the late 1450s. Although this was supposedly a period of temporary peace between the factions, Clifford and his allies appear to have made numerous attempts to ambush the Neville and Yorkist lords.
