The Battle of Bosworth or Bosworth Field ( BOZ-wərth) was the last significant battle of the Wars of the Roses, the civil war between the houses of Lancaster and York that extended across England and Wales in the latter half of the 15th century. Fought on 22 August 1485, the battle was won by an alliance of Lancastrians and disaffected Yorkists. Their leader Henry Tudor, Earl of Richmond, became the first Welsh monarch of England from the House of Tudor by his victory and subsequent marriage to the de facto Yorkist heiress, Elizabeth of York. His opponent Richard III, the last king of the House of York, was killed during the battle, the last English monarch to fall in 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 ascended the throne after his twelve-year-old nephew, Edward V, was declared illegitimate, likely at Richard's instigation. The boy and his younger brother Richard soon disappeared, and their fate remains a mystery. 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 foundered in a storm, but his second arrived unopposed on 7 August 1485 on the south-west coast of Wales. Marching inland, Henry gathered support as he made for London. Richard hurriedly mustered his troops and intercepted Henry's army near Ambion Hill, south of the town of Market Bosworth in Leicestershire. Lord Stanley and Sir William Stanley also brought a force to the battlefield, but held back while they decided which side it would be most advantageous to support, initially lending only four knights to Henry's cause: Sir Robert Tunstall, Sir John Savage (nephew of Lord Stanley), Sir Hugh Persall and Sir Humphrey Stanley. Sir John Savage was placed in command of the left flank of Henry's army.
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 gambled 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.
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, marking the end of the Middle Ages for England. From the 15th to the 18th centuries the battle was glamourised as a victory of good over evil, and features as the climax of William Shakespeare's play Richard III. 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 that has since been challenged by several scholars and historians. In October 2009, a team of researchers who had performed geological surveys and archaeological digs in the area since 2003 suggested a location two miles (3 km) south-west 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 Westminster, 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, which was a semi-independent duchy, where they were taken into the custody of Duke Francis II. Henry's mother, Lady Margaret Beaufort, was a great-granddaughter of John of Gaunt, uncle of King Richard II and father of King Henry IV. The Beauforts were originally bastards, but Richard II legitimised them through an Act of Parliament, a decision quickly modified by a royal decree of Henry IV ordering 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". The Duke of Brittany, however, viewed Henry as a valuable tool to bargain for England's aid in conflicts with France, and kept the Tudors under his protection.
Edward IV died 12 years after Tewkesbury in April 1483. His 12-year-old elder son succeeded him as King Edward V; the younger son, nine-year-old Richard of Shrewsbury, Duke of York, 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. Some among the council were worried when it became apparent that the relatives of Edward V's mother, Elizabeth Woodville, were plotting to use their control of the young king to dominate 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—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 Queen's brother Anthony Woodville, 2nd Earl Rivers, and her son by her first marriage Richard Grey 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 the Three Estates of the Realm, an informal Parliament declared the marriage between Edward IV and Elizabeth illegal, rendering their children illegitimate and disqualifying them from the throne. With his brother's children 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.
In October 1483, a conspiracy emerged to displace Richard from the throne. The rebels were mostly loyalists to Edward IV, who saw Richard as a usurper. Their plans were coordinated 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 fact, 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 in Rennes Cathedral 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. Later findings though, showed that Richard had entered into negotiations to marry Joanna of Portugal and to marry off Elizabeth to Manuel, Duke of Beja. The gossip must have 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 Elizabeth as his bride, Henry recruited mercenaries formerly in French service to supplement his following of exiles and set sail from France on 1 August.
Factions
By the 15th century, English chivalric ideas of selfless service to the king had been corrupted. Armed forces were raised mostly through musters in individual estates; every able-bodied man had to respond to his lord's call to arms, and each noble had authority over his militia. Although a king could raise personal militia from his lands, he could muster a large army only 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 very 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 had served Richard's brother for many years and had been one of Edward IV's closer confidants. 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 bore 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 ascension to 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.
