Battle of Bosworth Field

The Battle of Bosworth Field (or the Battle of Bosworth) was the penultimate battle of the Wars of the Roses, the civil war between the House of Lancaster and the House of York that raged across England in the latter half of the 15th century. Fought on Event date::22 August 1485, the battle was won by the Lancastrians. Their leader Henry Tudor, Earl of Richmond, became the first English monarch of the Tudor dynasty by his victory and subsequent marriage to a Yorkist princess. His opponent Richard III, the last king of the House of York, was killed in the battle. Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it one of the defining moments of English history.

Richard's reign began in 1483 when he seized the throne from his twelve-year-old nephew Edward V. The boy and his younger brother soon disappeared, to the distress of many, and Richard's support was further eroded by rumours of his involvement in the death of his wife. Across the English Channel Henry Tudor, a descendant of the greatly diminished House of Lancaster, seized on Richard's difficulties and laid claim to the throne. Henry's first attempt to invade England in 1483 was frustrated by a storm, but his second arrived unopposed on 1 August 1485 on the southwest coast of Wales. Marching inland, Henry gathered support as he made for London. Richard hurriedly mustered his troops and intercepted Henry's army south of the town of Market Bosworth in Leicestershire. Lord Thomas Stanley and Sir William Stanley also brought a force to the battlefield, but held back while they decided which side it would be more advantageous to support.

Richard divided his army, which outnumbered Henry's, into three groups (or "battles"). One was assigned to the Duke of Norfolk and another to the Earl of Northumberland. Henry kept most of his force together and placed it under the command of the experienced Earl of Oxford. Richard's vanguard, commanded by Norfolk, attacked but struggled against Oxford's men, and some of Norfolk's troops fled the field. Northumberland took no action when signalled to assist his king, so Richard decided to gamble everything on a charge across the battlefield to kill Henry and end the fight. Seeing the king's knights separated from his army, the Stanleys intervened; Sir William led his men to Henry's aid, surrounding and killing Richard. After the battle, Henry was crowned king on Crown Hill.

Henry hired chroniclers to portray his reign favourably; the Battle of Bosworth Field was popularised to represent his Tudor dynasty as the start of a new age. From the 15th to 18th centuries the battle was glamorised as a victory of good over evil, and as the climax of William Shakespeare's play about Richard's rise and fall, it provides a focal point for critics in later film adaptations. The exact site of the battle is disputed because of the lack of conclusive data, and memorials have been erected at different locations. The Bosworth Battlefield Heritage Centre was built, in 1974, on a site chosen based on a theory that has been challenged by several scholars and historians in the following years. In October 2009, a team of researchers, who had performed geological surveys and archaeological digs in the area from 2003, suggested a location two miles (3 km) southwest of Ambion Hill.

Background
During the 15th century, civil war raged across England as the Houses of York and Lancaster fought each other for the English throne. In 1471, the Yorkists defeated their rivals in the battles of Barnet and Tewkesbury. The Lancastrian King Henry VI and his only son, Edward of Lancaster, died in the aftermath of the Battle of Tewkesbury. Their deaths left the House of Lancaster with no direct claimants to the throne. The Yorkist king, Edward IV, was in complete control of England. He attainted those who refused to submit to his rule, such as Jasper Tudor and his nephew Henry, naming them traitors and confiscating their lands. The Tudors tried to flee to France but strong winds forced them to land in Brittany, then a semi-independent duchy, where they were taken into the custody of Francis II, Duke of Brittany. Henry's mother, Lady Margaret Beaufort, was a distant descendant of John of Gaunt, uncle of King Richard II and father of King Henry IV. The Beauforts were originally bastards, but Henry IV legitimated them on the condition that their descendants were not eligible to inherit the throne. Henry Tudor, the only remaining Lancastrian noble with a trace of the royal bloodline, had a weak claim to the throne, and Edward regarded him as "a nobody". Francis, however, viewed Henry as a valuable tool to bargain for England's aid and kept the Tudors under his protection.

Edward IV died twelve years later on 9 April 1483. His twelve-year-old elder son succeeded him as King Edward V; the younger son, nine-year-old Richard of Shrewsbury, was next in line to the throne. Edward V was too young to rule and a Royal Council was established to rule the country until the king's coming of age. The royal court was worried when they learned that the Woodvilles, relatives of the Queen Mother Elizabeth, were plotting to seize control of the council. Having offended many in their quest for wealth and power, the Woodville family was not popular. To frustrate the Woodvilles' ambitions, Lord Hastings and other members of the council turned to the new king's uncle&mdash;Richard, Duke of Gloucester, brother of Edward IV. The courtiers urged Gloucester to assume the role of Protector quickly, as had been previously requested by his now dead brother. On 29 April, Gloucester, accompanied by a contingent of guards and Henry Stafford, 2nd Duke of Buckingham, took Edward V into custody and arrested several prominent members of the Woodville family. After bringing the young king to London, Gloucester had the Woodvilles executed, without trial, on charges of treason.

On 13 June, Gloucester accused Hastings of plotting with the Woodvilles and had him beheaded. Nine days later, Gloucester convinced Parliament to declare the marriage between Edward IV and Elizabeth illegal, rendering their children illegitimate and disqualifying them from the throne. With his nephews out of the way, he was next in the line of succession and was proclaimed King Richard III on 26 June. The timing and extrajudicial nature of the deeds done to obtain the throne for Richard won him no popularity, and rumours that spoke ill of the new king spread throughout England. After they were declared bastards, the two princes were confined in the Tower of London and never seen in public again. Except for those in the north, the people of England firmly believed that Richard, the "tyrant", had murdered his nephews.

Discontent with Richard's actions manifested itself in the summer after he took control of the country, as a conspiracy emerged to displace him from the throne. The rebels were mostly loyalists to Edward IV, who saw Richard as a usurper. Their plans were co-ordinated by a Lancastrian, Henry's mother Lady Margaret, who was promoting her son as a candidate for the throne. The highest-ranking conspirator was Buckingham. No chronicles tell of the duke's motive in joining the plot, although historian Charles Ross proposes that Buckingham was trying to distance himself from a king who was becoming increasingly unpopular with the people. Michael Jones and Malcolm Underwood suggest that Margaret deceived Buckingham into thinking the rebels supported him to be king.

The plan was to stage uprisings within a short time in southern and western England, overwhelming Richard's forces. Buckingham would support the rebels by invading from Wales, while Henry came in by sea. Bad timing and weather wrecked the plot. An uprising in Kent started 10 days prematurely, alerting Richard to muster the royal army and take steps to put down the insurrections. Richard's spies informed him of Buckingham's activities, and the king's men captured and destroyed the bridges across the River Severn. When Buckingham and his army reached the river, they found it swollen and impossible to cross because of a violent storm that broke on 15 October. Buckingham was trapped and had no safe place to retreat; his Welsh enemies seized his home castle after he had set forth with his army. The duke abandoned his plans and fled to Wem, where he was betrayed by his servant and arrested by Richard's men. On 2 November, he was executed. Henry had attempted a landing on 10 October (or 19 October), but his fleet was scattered by a storm. He reached the coast of England (at either Plymouth or Poole), and a group of soldiers hailed him to come ashore. They were, in truth, Richard's men, prepared to capture Henry once he set foot on English soil. Henry was not deceived and returned to Brittany, abandoning the invasion. Without Buckingham or Henry, the rebellion was easily crushed by Richard.

The survivors of the failed uprisings fled to Brittany, where they openly supported Henry's claim to the throne. At Christmas, Henry Tudor swore an oath to marry Edward IV's daughter, Elizabeth of York, to unite the warring houses of York and Lancaster. Henry's rising prominence made him a great threat to Richard, and the Yorkist king made several overtures to the Duke of Brittany to surrender the young Lancastrian. Francis refused, holding out for the possibility of better terms from Richard. In mid-1484, Francis was incapacitated by illness and while recuperating, his treasurer, Pierre Landais, took over the reins of government. Landais reached an agreement with Richard to send back Henry and his uncle in exchange for military and financial aid. John Morton, a bishop of Flanders, learned of the scheme and warned the Tudors, who fled to France. The French court allowed them to stay; the Tudors were useful pawns to ensure that Richard's England did not interfere with French plans to annex Brittany. On 16 March 1485, Richard's queen, Anne Neville, died, and rumours spread across the country that she was murdered to pave the way for Richard to marry his niece, Elizabeth. The gossip alienated Richard from some of his northern supporters, and upset Henry across the English Channel. The loss of Elizabeth's hand in marriage could unravel the alliance between Henry's supporters who were Lancastrians and those who were loyalists to Edward IV. Anxious to secure his bride, Henry assembled approximately 2,000 men and set sail from France on 1 August.

Commanders
By the 15th century, English chivalric ideas of selfless service to the king had been corrupted. Armed forces were mostly raised through musters in individual estates; every able-bodied man had to respond to their lord's call to arms, and each noble had exclusive authority over his militia. Although a king could raise personal militia from his lands, he could only muster a significantly large army through the support of his nobles. Richard, like his predecessors, had to win over these men by granting gifts and maintaining cordial relationships. Powerful nobles could demand greater incentives to remain on the liege's side or else they might turn against him. Three groups, each with its own agenda, stood on Bosworth Field: Richard III and his Yorkist army; his challenger, Henry Tudor, who championed the Lancastrian cause; and the fence-sitting Stanleys.

Yorkist
Small and slender, Richard III did not have the robust physique associated with many of his Plantagenet predecessors. However, he enjoyed rough sports and activities that were considered manly. His performances on the battlefield impressed his brother greatly, and he became Edward's right hand man. During the 1480s, Richard defended the northern borders of England. In 1482, Edward charged him to lead an army into Scotland with the aim of replacing King James III with the Duke of Albany. Richard's army broke through the Scottish defences and occupied the capital, Edinburgh, but Albany decided to give up his claim to the throne in return for the post of Lieutenant General of Scotland. As well as obtaining a guarantee that the Scottish government would concede territories and diplomatic benefits to the English crown, Richard's campaign retook the town of Berwick-upon-Tweed, which the Scots had conquered in 1460. Edward was not satisfied by these gains, which, according to Ross, could have been greater if Richard had been resolute enough to capitalise on the situation while in control of Edinburgh. In her analysis of Richard's character, Christine Carpenter sees him as a soldier who was more used to taking orders than giving them. However, he was not averse to displaying his militaristic streak; on ascending the throne he made known his desire to lead a crusade against "not only the Turks, but all [his] foes".

Richard's most loyal subject was John Howard, 1st Duke of Norfolk. The duke served Richard's brother for many years and was one of Edward IV's closer confidantes. He was a military veteran, having fought in the Battle of Towton in 1461 and served as Hastings' deputy at Calais in 1471. Ross speculates that he may have borne a grudge against Edward for depriving him of a fortune. Norfolk was due to inherit a share of the wealthy Mowbray estate on the death of eight-year-old Anne de Mowbray, the last of her family. However, Edward convinced Parliament to circumvent the law of inheritance and transfer the estate to his younger son, who was married to Anne. Consequently, Howard supported Richard III in deposing Edward's sons, for which he received the dukedom of Norfolk and his original share of the Mowbray estate.

Henry Percy, 4th Earl of Northumberland, also supported Richard's seizure of the throne of England. The Percys were loyal Lancastrians, but Edward IV eventually won the earl's allegiance. Northumberland had been captured and imprisoned by the Yorkists in 1461, losing his titles and estates; however, Edward released him eight years later and restored his earldom. From that time Northumberland served the Yorkist crown, helping to defend northern England and maintain its peace. Initially the earl had issues with Richard III as Edward groomed his brother to be the leading power of the north. Northumberland was mollified when he was promised he would be the Warden of the East March, a position that was formerly hereditary for the Percys. He served under Richard during the 1482 invasion of Scotland, and the allure of being in a position to dominate the north of England if Richard went south to assume the crown was his likely motivation for supporting Richard's bid for kingship. However, after becoming king, Richard began moulding his nephew, John de la Pole, 1st Earl of Lincoln, to manage the north, passing over Northumberland for the position. According to Carpenter, although the earl was amply compensated he despaired of any possibility of advancement under Richard.

Lancastrian
Henry Tudor was unfamiliar with the arts of war and a stranger to the land he was trying to conquer. He spent the first fourteen years of his life in Wales and the next fourteen in Brittany and France. Slender but strong and decisive, Henry lacked a penchant for battle and was not much of a warrior; chroniclers such as Polydore Vergil and ambassadors like Pedro de Ayala found him more interested in commerce and finance. Having not fought in any battles, Henry recruited several experienced veterans on whom he could rely for military advice and the command of his armies.

John de Vere, 13th Earl of Oxford, was Henry's principal military commander. He was adept in the arts of war. At the Battle of Barnet, he commanded the Lancastrian right wing and routed the division opposing him. However, as a result of confusion over identities, Oxford's group came under friendly fire from the Lancastrian main force and retreated from the field. The earl fled abroad and continued his fight against the Yorkists, raiding shipping and eventually capturing the island fort of St Michael's Mount in 1473. He surrendered after receiving no aid or reinforcement, but in 1484 escaped from prison and joined Henry's court in France, bringing along his erstwhile gaoler Sir James Blount. Oxford's presence raised morale in Henry's camp and troubled Richard III.

Stanleys
In the early stages of the Wars of the Roses the Stanleys of Cheshire were predominantly Lancastrians. Sir William Stanley, however, was a staunch Yorkist supporter, fighting in the Battle of Blore Heath in 1459 and helping Hastings to put down uprisings against Edward IV in 1471. When Richard took the crown, Sir William showed no inclination to turn against the new king, refraining from joining Buckingham's rebellion, for which he was amply rewarded. Sir William's elder brother, Thomas Stanley, 2nd Baron Stanley, was not as steadfast. By 1485, he had served three kings, namely Henry VI, Edward IV, and Richard III. Lord Stanley's skilled political manoeuvrings&mdash;vacillating between opposing sides until it was clear who would be the winner&mdash;gained him high positions; he was Henry's chamberlain and Edward's steward. His non-committal stance, until the crucial point of a battle, earned him the loyalty of his men, who felt he would not needlessly send them to their deaths.

Even though Lord Stanley had served as Edward IV's steward, his relations with the king's brother, the eventual Richard III, were not cordial. The two had conflicts with each other that erupted into violence around March 1470. Furthermore, having taken Lady Margaret as his second wife in June 1472, Stanley was Henry Tudor's stepfather, a relationship which did him nothing to win Richard's favour. Despite these differences, Stanley did not join Buckingham's revolt in 1483. When Richard executed those conspirators who were unable to flee England, he spared Lady Margaret. However, he declared her titles forfeit, and transferred her estates to Stanley's name, to be held in trust for the Yorkist crown. Richard's act of mercy was calculated to reconcile with Stanley, but it may have been to no avail—Carpenter has identified a further cause of friction in Richard's intention to reopen an old land dispute that involved Thomas Stanley and the Harrington family. Edward IV had ruled the case in favour of Stanley in 1473, but Richard planned to overturn his brother's ruling and give the wealthy estate to the Harringtons. Wary of Stanley, Richard took his son, Lord Strange, as hostage to discourage him from joining Henry.

Prelude
Henry's crossing of the English Channel in 1485 was without incident. He sailed from Harfleur on 1 August and, with fair winds, landed at Mill Bay on the north side of Milford Haven on 7 August, easily capturing nearby Dale Castle. Although hailed by contemporary Welsh bards as the native prince to bring their country back to glory, Henry received a muted response from the local population. No joyous welcome awaited him on shore, and few individual Welshmen joined his army as it marched inland. Historian Geoffrey Elton suggests only Henry's ardent supporters felt pride over his Welsh blood. It was a different story when Henry moved to Haverfordwest, the county town of Pembrokeshire. Richard's lieutenant in South Wales, Sir Walter Herbert, failed to move against Henry, and two of his officers, Richard Griffith and Evan Morgan, deserted to Henry with their men. Another prominent local figure, Rhys Fawr ap Maredudd, also joined Henry.

However, the most important defector to Henry in this early stage of the campaign was probably Rhys ap Thomas, who was the leading figure in West Wales. Richard had appointed Rhys Lieutenant in West Wales for his refusal to join Buckingham's rebellion, asking that he surrender his son Gruffydd ap Rhys ap Thomas as surety, although by some accounts Rhys had managed to evade this condition. However, Henry successfully courted Rhys, offering the lieutenancy of all Wales in exchange for his fealty. Henry marched via Aberystwyth while Rhys followed a more southerly route, recruiting 500 Welshmen en route to swell Henry's army when they reunited at Welshpool. By 15 or 16 August, Henry and his men had crossed the English border, making for the town of Shrewsbury.

Since 22 June 1485 Richard had been aware of Henry's impending invasion, and had ordered his lords to maintain a high level of readiness. News of Henry's landing reached Richard on 11 August, but it took three to four days for his messengers to notify his lords of their king's mobilisation. On 16 August, the Yorkist army started to gather; Norfolk set off for Leicester, the assembly point, that night. The city of York, a traditional stronghold of Richard's family, asked the king for instructions, and receiving a reply three days later sent 80 men to join the king. Simultaneously Northumberland, whose northern territory was the most distant from the capital, had gathered his men and ridden to Leicester.

Although London was his goal, Henry did not move directly towards the city. After resting in Shrewsbury, his forces went eastwards and picked up Gilbert Talbot and other English allies, including deserters from Richard's forces. Although its size had increased substantially since the landing, Henry's army was not yet large enough to contend with the numbers Richard could muster. Henry's pace through Staffordshire was slow, delaying the confrontation with Richard so that he could gather more recruits to his cause. Henry had been communicating on friendly terms with the Stanleys for some time before setting foot in England, and the Stanleys had mobilised their forces on hearing of Henry's landing. They ranged themselves ahead of Henry's march through the English countryside, meeting twice in secret with Henry as he moved through Staffordshire. At the second of these, at Atherstone in Warwickshire, they conferred "in what sort to arraign battle with King Richard, whom they heard to be not far off". On 21 August, the Stanleys were making camp on the slopes of a hill north of Dadlington, while Henry encamped his army at White Moors to the northwest of their camp.

On 20 August, Richard reached Leicester, joining Norfolk. Northumberland arrived the following day. The royal army proceeded westwards to intercept Henry's march on London. Passing Sutton Cheney, Richard moved his army towards Ambion Hill—which he thought would be of tactical value—and made camp on it. Richard's sleep was not peaceful and, according to the Croyland Chronicle, in the morning his face was "more livid and ghastly than usual".

Engagement


The Yorkist army, numbering about 10,000 men, deployed on the hilltop along the ridgeline from west to east. Norfolk's group (or "battle" in the parlance of the time) of spearmen stood on the right flank, protecting the cannon and about 1,200 archers. Richard's group, comprising 3,000 infantry, formed the centre. Northumberland's men guarded the left flank; he had approximately 4,000 men, many of them mounted. Standing on the hilltop, Richard had a wide, unobstructed view of the area. He could see the Stanleys and their 6,000 men holding their position at Dadlington Hill, while to the southwest was Henry's army.

Henry had very few Englishmen&mdash;fewer than a thousand&mdash;in his army. Between three and five hundred of them were exiles who had fled from Richard's rule, and the remainder were Talbot's men and recent deserters from Richard's army. Historian John Mackie believes that 1,800 French mercenaries, led by Philibert de Chandée, formed the core of Henry's army. John Mair, writing thirty-five years after the battle, claimed that this force contained a significant Scottish component, and this claim is accepted by some modern writers, but Mackie reasons that the French would not have released their elite Scottish knights and archers, and concludes that there were probably few Scottish troops in the army, although he accepts the presence of captains like Bernard Stewart, Lord of Aubigny. In total, Henry's army was around 5,000 strong, a substantial portion of which was made up by the recruits picked up in Wales. Rhys ap Thomas's Welsh force was described as being large enough to have "annihilated" the rest of Henry's force.

In their interpretations of the vague mentions of the battle in the old text, historians placed areas near the foot of Ambion Hill as likely regions where the two armies clashed, and thought up possible scenarios of the engagement. In their recreations of the battle, Henry started by moving his army towards Ambion Hill where Richard and his men stood. As Henry's army advanced past the marsh at the southwestern foot of the hill, Richard sent a message to Stanley, threatening to execute his son, Strange, if Stanley did not join the attack on Henry immediately. Stanley replied that he had other sons. Incensed, Richard gave the order to behead Strange but his officers temporised, saying that battle was imminent, and it would be more convenient to carry out the execution afterwards. Henry had also sent messengers to Stanley asking him to declare his allegiance. The reply was evasive&mdash;the Stanleys would "naturally" come, after Henry had given orders to his army and arranged them for battle. Henry had no choice but to confront Richard's forces alone.

Well aware of his own military inexperience, Henry handed command of his army to Oxford and retired to the rear with his bodyguards. Oxford, seeing the vast line of Richard's army strung along the ridgeline, decided to keep his men together instead of splitting them into the traditional three battles: vanguard, centre, and rearguard. He ordered the troops to stray no further than 10 ft from their banners, fearing that they would become enveloped. Individual groups clumped together, forming a single large mass flanked by horsemen on the wings.

The Lancastrians were harassed by Richard's cannon as they manoeuvred around the marsh, seeking firmer ground. Once Oxford and his men were clear of the marsh, Norfolk's battle and several contingents of Richard's group started to advance. Hails of arrows showered both sides as they closed. Oxford's men proved the steadier in the ensuing hand-to-hand combat; they held their ground and several of Norfolk's men, recruits from southern England, fled the field. Recognising that his force was at a disadvantage, Richard signalled for Northumberland to assist but Northumberland's group showed no signs of movement. Historians, such as Horrox and Pugh, believe Northumberland chose not to aid his king for personal reasons. Ross doubts the aspersions cast on Northumberland's loyalty, suggesting instead that Ambion Hill's narrow ridge hindered him from joining the battle. The earl would have had to either go through his allies or execute a wide flanking move&mdash;near impossible to perform given the standard of drill at the time&mdash;to engage Oxford's men.

At this juncture Henry rode off towards the Stanleys. Seeing this, Richard decided to end the fight quickly by killing the enemy commander. He led a charge of mounted men around the melee and tore into Henry's group; several accounts state that Richard's force numbered 800–1000 knights, but Ross says it was more likely that Richard was accompanied only by his household men and closest friends. Richard killed Henry's standard-bearer Sir William Brandon in the initial charge and unhorsed burly John Cheyne, Edward IV's former standard-bearer, with a blow to the head from his broken lance. Henry's bodyguards surrounded their master and succeeded in keeping him away from the Yorkist king. On seeing Richard embroiled with Henry's men and separated from his main force, William Stanley made his move. He led his men into the fight at Henry's side. Outnumbered, Richard's group was surrounded and gradually pressed back against the marsh. Richard's banner man&mdash;Sir Percival Thirwell&mdash;lost his legs but held the Yorkist banner aloft until he was hacked to death. The king's horse got mired in the soft ground and he was forced to continue the fight on foot. His followers offered him their horses to escape but Richard refused. All chroniclers agree that Richard fought bravely to the end; overwhelmed by the masses of Welsh spearmen around him, the last Yorkist king died on the battlefield. Richard's forces disintegrated as news of his death spread. Northumberland and his men fled north on seeing the king's fate, and Norfolk was killed.

Post-battle
After the battle, Richard's circlet was found and brought to Henry, who was crowned king at the top of Crown Hill, near the village of Stoke Golding. According to Vergil, Henry's official historian, Lord Stanley found the circlet. Historian Stanley Chrimes and Professor Sydney Anglo dismiss the legend of the crown's finding in a hawthorn bush; none of the contemporary sources reported such an event. Ross, however, does not ignore the legend. He opines that the hawthorn bush would not be part of Henry's coat of arms if it did not have a strong relationship to his ascendance. In Vergil's chronicle, 100 of Henry's men, compared to 1,000 of Richard's, died in this battle&mdash;a ratio Chrimes believes to be an exaggeration. The bodies of the fallen were brought to St James Church at Dadlington for burial. However, Henry denied any immediate rest for Richard; instead the last Yorkist king's corpse was stripped naked and strapped across a horse. His body was brought to Leicester and openly exhibited in a church to show his death. After two days, the corpse was interred in a plain unmarked tomb.

Henry dismissed the mercenaries in his force, retaining only a small core of local soldiers to form the "Yeomen of his Garde", and proceeded to establish his rule of England. Parliament reversed his attainder and recorded Richard's kingship as illegal, although the Yorkist king's reign remained officially in the annals of England history. The proclamation of Edward IV's children as illegitimate was also reversed, restoring Elizabeth's status to a royal princess. The marriage of Elizabeth, the heiress to the House of York, to Henry, the master of the House of Lancaster, marked the end of the feud between the two houses and the start of the Tudor dynasty. The royal matrimony, however, was delayed until Henry was crowned king and had established his claim on the throne firmly enough to preclude that of Elizabeth and her kin. Henry further convinced Parliament to backdate his reign to the day before the battle, effectively enabling those who fought against him at Bosworth Field to be declared traitors. Northumberland, who had remained inactive during the battle, was imprisoned but later released and reinstated to pacify the north in Henry's name. The purge of those who fought for Richard occupied Henry's first two years of rule, although later he proved prepared to accept those who submitted to him regardless of their former allegiances.

Of his supporters, Henry rewarded the Stanleys the most generously. Aside from making William his chamberlain, he bestowed the earldom of Derby upon Lord Stanley along with grants and offices in other estates. Henry rewarded Oxford by restoring to him the lands and titles confiscated by the Yorkists and appointing him as Constable of the Tower and admiral of England, Ireland, and Aquitaine. For his kin, Henry created Jasper Tudor the Duke of Bedford. He returned to his mother the lands and grants stripped from her by Richard, and proved to be a filial son, installing her as Queen Mother in the palace and faithfully attending to her throughout his reign. Parliament's declaration of Margaret as femme sole effectively empowered her; she no longer needed to manage her estates through Stanley. Elton points out that despite his initial largesse, Henry's supporters at Bosworth would only enjoy his special favour for the short term; in later years, he would instead promote those who best served his interests.

Like the kings before him, Henry faced dissenters. The first open revolt occurred two years after Bosworth Field; Lambert Simnel claimed to be Edward Plantagenet, 17th Earl of Warwick, who was Edward IV's nephew. The Earl of Lincoln backed him for the throne and led rebel forces in the name of the House of York. The rebel army fended off several attacks by Northumberland's forces, before engaging Henry's army at the Battle of Stoke Field on 16 June 1487. Oxford and Bedford led Henry's men, including several former supporters of Richard III. Henry won this battle easily, but other malcontents and conspiracies would follow. A rebellion in 1489 started with Northumberland's murder; military historian Michael C. C. Adams says that the author of a note, which was left next to Northumberland's body, blamed the earl for Richard's death.

Legacy
Contemporary accounts of the Battle of Bosworth Field can be found in four main sources, one of which is the English Croyland Chronicle, written by a senior Yorkist chronicler who relied on second-hand information from nobles and soldiers. The other accounts were written by foreigners&mdash;Vergil, Jean Molinet, and Diego de Valera. Whereas Molinet was sympathetic to Richard, Vergil was in Henry's service and drew information from the king and his subjects to portray them in a good light. Diego de Valera, whose information Ross regards as unreliable, compiled his work from letters of Spanish merchants. However, other historians have used Valera's work to deduce possibly valuable insights not readily evident in other sources. Ross finds the poem, The Ballad of Bosworth Field, a useful source to ascertain certain details of the battle. The multitude of different accounts, mostly based on second- or third-hand information, has proved an obstacle to historians as they try to reconstruct the battle. Their common complaint is that, except for its outcome, very few details of the battle are found in the chronicles. According to historian Michael Hicks, the Battle of Bosworth Field is one of the worst-recorded clashes of the Wars of the Roses.

Henry tried to present his victory as a new beginning for the country; he hired chroniclers to portray his reign as a "modern age" with its dawn in 1485. Hicks states that the works of Vergil and the blind historian Bernard André, promoted by subsequent Tudor administrations, became the authoritative sources for writers for the next four hundred years. As such, Tudor literature paints a flattering picture of Henry's reign, depicting the Battle of Bosworth Field as the final clash of the civil war and downplaying the subsequent uprisings. For England the Middle Ages ended in 1485, and English Heritage claims that other than William the Conqueror's successful invasion of 1066, no other year holds more significance in English history. By portraying Richard as a hunchbacked tyrant who usurped the throne by killing his nephews, the Tudor historians attached a sense of myth to the battle: it became an epic clash between good and evil with a satisfying moral outcome. According to Reader Colin Burrow, André was so overwhelmed by the historic significance of the battle that he represented it with a blank page in his Henry VII (1502). For Professor Peter Saccio, the battle was indeed a unique clash in the annals of English history, because "the victory was determined, not by those who fought, but by those who delayed fighting until they were sure of being on the winning side."

Historians such as Adams and Horrox believe that Richard lost the battle not for any mythic reasons, but because of morale and loyalty problems in his army. Most of the common soldiers found it difficult to fight for a liege whom they distrusted, and some lords believed that their situation might improve if Richard was dethroned. According to Adams, against such duplicities Richard's desperate charge was the only knightly behaviour on the field. As fellow historian Michael Bennet puts it, the attack was "the swan-song of [mediaeval] English chivalry". Adams believes this view was shared at the time by the printer William Caxton, who enjoyed sponsorship from Edward IV and Richard III. Nine days after the battle, Caxton published Thomas Malory's story about chivalry and death by betrayal&mdash;Le Morte d'Arthur&mdash;seemingly as a response to the circumstances of Richard's death.

Elton does not believe Bosworth Field has any true significance, pointing out that the 20th century English public largely ignored the battle until its quincentennial celebration. In his view, the dearth of specific information about the battle&mdash;no-one even knows exactly where it took place&mdash;demonstrates its insignificance to English society. Elton considers the battle as just one part of Henry's struggles to establish his reign, underscoring his point by noting that the young king had to spend ten more years pacifying factions and rebellions to secure his throne. Mackie agrees that contemporary historians, wary of the three royal successions during the long Wars of the Roses, considered Bosworth Field just another in a lengthy series of such battles. It was through the works and efforts of Francis Bacon and his successors that the public started to believe the battle had decided their futures by bringing about "the fall of a tyrant". Mackie concludes that, in hindsight, Bosworth Field is notable as the decisive battle that established a dynasty which would rule unchallenged over England for more than a hundred years.

Shakespearian dramatisation
William Shakespeare gives prominence to the Battle of Bosworth Field in his play, Richard III. It is the "one big battle"; no other fighting scene distracts the audience from this action, represented by a one-on-one swordfight between Henry Tudor and Richard III. Shakespeare uses their duel to bring a climactic end to the play and the Wars of the Roses; he also uses it to champion morality, portraying the "unequivocal triumph of good over evil". Richard, the villainous lead character, has been built up in the battles of Shakespeare's earlier play, Henry VI, Part 3, as a "formidable swordsman and a courageous military leader"&mdash;in contrast to the dastardly means by which he becomes king in Richard III. Although the Battle of Bosworth Field has only five sentences to direct it, three scenes and more than four hundred lines precede the action, developing the background and motivations for the characters in anticipation of the battle.

Shakespeare's account of the battle was mostly based on chroniclers Edward Hall's and Raphael Holinshed's dramatic versions of history, which were sourced from Vergil's chronicle. However, Shakespeare's attitude towards Richard was shaped by scholar Thomas More, whose writings displayed extreme bias against the Yorkist king. The result of these influences is a script that vilifies the king, and Shakespeare had few qualms about departing from history to incite drama. Margaret of Anjou died in 1482, but Shakespeare had her speak to Richard's mother before the battle to foreshadow Richard's fate and fulfil the prophecy she had given in Henry VI. Shakespeare exaggerated the cause of Richard's restless night before the battle, imagining it as a haunting by the ghosts of those whom the king had murdered, including Buckingham. Richard is portrayed as suffering a pang of conscience, but as he speaks he regains his confidence and asserts that he will be evil, if such needed to retain his crown.

The fight between the two armies is simulated by rowdy noises made off-stage (alarums or alarms) while actors walk on-stage, deliver their lines, and exit. To build anticipation for the duel, Shakespeare requests more alarums after Richard's councillor, William Catesby, announces that the king is "[enacting] more wonders than a man". Richard punctuates his entrance with the classic line, "A horse, a horse! My kingdom for a horse!" He refuses to withdraw, continuing to seek to slay Henry's doubles until he has killed his nemesis. There is no documentary evidence that Henry had five decoys at Bosworth Field; the idea was Shakespeare's invention. He drew inspiration from Henry IV's use of them at the Battle of Shrewsbury (1403) to amplify the perception of Richard's courage on the battlefield. Similarly, the single combat between Henry and Richard is Shakespeare's creation. The True Tragedy of Richard III, a play earlier than Shakespeare's, has no signs of staging such an encounter: its stage directions give not a hint of visible combat.

Despite the dramatic licences taken, Shakespeare's version of the Battle of Bosworth Field was the model of the event for English textbooks for many years during the 18th and 19th centuries. This glamorised version of history, promulgated in books and paintings and played out on stages across the country, perturbed humorist Gilbert Abbott à Beckett. He voiced his criticism in the form of a poem, equating the romantic view of the battle to watching a "fifth-rate production of Richard III": shabbily costumed actors fight the Battle of Bosworth Field on-stage while those with lesser roles lounge at the back, showing no interest in the proceedings.

In Laurence Olivier's 1955 film adaptation of Richard III, the Battle of Bosworth Field is represented not by a single duel but a general melee that became the film's most recognised scene and a regular screening at Bosworth Battlefield Heritage Centre. The film depicts the clash between the Yorkist and Lancastrian armies on an open field, focusing on individual characters amidst the savagery of hand-to-hand fighting, and received accolades for the realism portrayed. One reviewer for The Manchester Guardian newspaper, however, was not impressed, finding the number of combatants too sparse for the wide plains and a lack of subtlety in Richard's death scene. The means by which Richard is shown to prepare his army for the battle also earned acclaim. As Richard speaks to his men and draws his plans in the sand using his sword, his units appear on-screen, arraying themselves according to the lines that Richard had drawn. Intimately woven together, the combination of pictorial and narrative elements effectively turns Richard into a storyteller, who acts out the plot he has constructed. Shakespearian critic Herbert Coursen extends that imagery: Richard sets himself up as a creator of men, but dies amongst the savagery of his creations. Coursen finds the depiction a contrast to that of Henry V and his "band of brothers".

The adaptation of the setting for Richard III to a 1930s fascist England in Ian McKellen's 1995 film, however, did not sit well with historians. Adams posits that the original Shakespearian setting for Richard's fate at Bosworth teaches the moral of facing one's fate, no matter how unjust it is, "nobly and with dignity". By overshadowing the dramatic teaching with special effects, McKellen's film reduces its version of the battle to a pyrotechnic spectacle about the death of a one-dimensional villain. Coursen agrees that, in this version, the battle and Richard's end are trite and underwhelming.

Battlefield
Officially the site of the battle is deemed by Leicestershire County Council to be in the vicinity of the town of Market Bosworth. The council engaged historian Daniel Williams to research the battle, and in 1974 his findings were used to build the Bosworth Battlefield Heritage Centre and the presentation it houses. Williams's interpretation, however, has since been questioned. Sparked by the battle's quincentenary celebration in 1985, a dispute among historians has led many to suspect the accuracy of Williams's theory. In particular, geological surveys conducted from 2003 to 2009 by the Battlefields Trust, a charitable organisation that protects and studies old English battlefields, show that the southern and eastern flanks of Ambion Hill were solid ground in the 15th century, contrary to Williams's claim that it was a large area of marshland. Landscape archaeologist Glenn Foard, leader of the survey, said the collected soil samples and finds of mediaeval military equipment suggest that the battle took place two miles (3 km) southwest of Ambion Hill (52°34′41″N 1°26′02″W), contrary to the popular belief that it was fought near the foot of the hill.

English Heritage argues that the battle was named after Market Bosworth because the town was the nearest significant settlement to the battlefield in the 15th century. As explored by Professor Philip Morgan, a battle might initially be treated by society as an unremarkable event, deeming it of no memorable quality and therefore not requiring a name. As time passes, writers of administrative and historical records find it necessary to identify the battle, ascribing it a name that is usually toponymical in nature and sourced from combatants or observers. This official name becomes accepted by society and future generations without question. Early records associated the Battle of Bosworth Field with "Brownehethe", "bellum Miravallenses", "Sandeford" and "Dadlyngton field". The earliest record, a municipal memorandum of 23 August 1485 from York, locates the battle "on the field of Redemore". This is corroborated by a 1485–86 letter that mentions "Redesmore" as its site. According to historian Peter Foss, records did not associate the battle with "Bosworth" until 1510.

Foss is named by English Heritage as the principal advocate for "Redemore" as the battlesite. He suggests the name is derived from "Hreod Mor", an Anglo-Saxon phrase that means "reedy marshland". Basing his opinion on 13th- and 16th-century church records, he believes "Redemore" was an area of wetland that lay between Ambion Hill and the village of Dadlington, and was close to the Fenn Lanes, a Roman road running east to west across the region. Foard believes this road to be the most probable route that both armies took to reach the battlefield. Williams dismisses the notion of "Redmore" as a specific location, calling the word a general term used to describe a large area of reddish soil; Foss argues that Williams's sources are local stories and flawed interpretations of records. Moreover, he proposes that Williams was influenced by William Hutton's 1788 The Battle of Bosworth-Field, which Foss blames for introducing the notion that the battle was fought west of Ambion Hill on the north side of the River Sence. Hutton, as Foss suggests, misinterpreted a passage from his source, Raphael Holinshed's 1577 Chronicle. Holinshed wrote, "King Richard pitched his field on a hill called Anne Beame, refreshed his soldiers and took his rest." Foss believes that Hutton mistook "field" to mean "field of battle", thus creating the idea that the fight took place on Anne Beame (Ambion) Hill. To "[pitch] his field", as Foss clarifies, was a period expression for setting up a camp.

Foss brings further evidence for his "Redemore" theory by quoting Edward Hall's 1550 Chronicle. Hall stated that Richard's army stepped onto a plain after breaking camp the next day. Furthermore, historian William Burton, author of Description of Leicestershire (1622), wrote that the battle was "fought in a large, flat, plaine, and spacious ground, three miles [5 km] distant from [Bosworth], between the Towne of Shenton, Sutton [Cheney], Dadlington and Stoke [Golding]". In Foss's opinion both sources are describing an area of flat ground north of Dadlington.

English Heritage, responsible for managing England's historic sites, used both theories to designate the site for Bosworth Field. Without preference for either theory, they constructed a single continuous battlefield boundary that encompasses the locations proposed by both Williams and Foss. The region has experienced extensive changes over the years, starting after the battle. Holinshed stated in his chronicle that he found firm ground where he expected the marsh to be, and Burton confirmed that by the end of the 16th century, areas of the battlefield were enclosed and had been improved to make them agriculturally productive. Trees were planted on the south side of Ambion Hill, forming Ambion Wood. In the 18th and 19th centuries, the Ashby Canal carved through the land west and south-west of Ambion Hill. Winding alongside the canal at a distance, the Ashby and Nuneaton Joint Railway crossed the area on an embankment. The changes to the landscape were so extensive that when Hutton revisited the region in 1807 after an earlier 1788 visit, he could not readily find his way around.

Bosworth Battlefield Heritage Centre was built on Ambion Hill, near Richard's Well. According to legend, Richard III drank from one of the several springs in the region on the day of the battle. In 1788, a local pointed out one of the springs to Hutton as the one mentioned in the legend. A stone structure was later built over the location. The inscription on the well reads: ""Near this spot, on August 22nd 1485, at the age of 32, King Richard III fell fighting gallantly in defence of his realm & his crown against the usurper Henry Tudor.

The Cairn was erected by Dr. Samuel Parr in 1813 to mark the well from which the king is said to have drunk during the battle.

It is maintained by the Fellowship of the White Boar.""

Northwest of Ambion Hill, just across the northern tributary of the Sence, a flag and memorial stone mark Richard's Field. Erected in 1973, the site was selected on the basis of Williams's theory. St James's Church at Dadlington is the only structure in the area that is reliably associated with the Battle of Bosworth Field; the bodies of those killed in the battle were buried there.
