Norman preparations and forces William assembled a large invasion fleet and an army gathered from Normandy and all over France, including large contingents from
Brittany and Flanders. The exact numbers and composition of William's force are unknown. A contemporary document claims that William had 726 ships, but this may be an inflated figure. Figures given by contemporary writers are highly exaggerated, varying from 14,000 to 150,000 men. Modern historians have offered a range of estimates for the size of William's forces: 7000–8000 men, 1000–2000 of them cavalry; 10,000–12,000 men; or 7500 men. Although later lists of
companions of William the Conqueror are extant, most are padded with extra names; only about 35 individuals can be reliably claimed to have been with William at Hastings. Though contemporary historian
William of Poitiers states that William obtained
Pope Alexander II's consent for the invasion, signified by a papal banner, along with diplomatic support from other European rulers, these claims should be treated with caution and were probably made to strengthen William's claims to legitimacy.
Landing and Harold's march south depicting ships grounding and horses landing in England|thumb|upright=1.5|left The Normans crossed to England a few days after Harold's victory over the Norwegians at Stamford Bridge on 25 September, following the dispersal of Harold's naval force. They landed at
Pevensey in
Sussex on 28 September and erected a wooden castle at
Hastings, from which they raided the surrounding area. This ensured supplies for the army, and as Harold and his family held many of the lands in the area, it weakened William's opponent and made him more likely to attack to put an end to the raiding. After defeating Tostig and Harald Hardrada in the north, Harold left much of his force there, including Morcar and Edwin, and marched the rest of his army south to deal with the threatened Norman invasion. It is unclear when Harold learned of William's landing, but it was probably while he was travelling south. Harold stopped in London for about a week before reaching Hastings, so it is likely that he took a second week to march south, averaging about per day, for the nearly to London. Although Harold attempted to surprise the Normans, William's scouts reported the English arrival to the duke. The events preceding the battle remain obscure, with contradictory accounts in the sources, but all agree that William led his army from his castle and advanced towards the enemy. Harold had taken up a defensive position at the top of Senlac Hill (present-day
Battle, East Sussex), about from William's castle at Hastings. Contemporary sources do not give reliable data on the size and composition of Harold's army, although two Norman sources give figures of 1.2 million or 400,000 men. Recent historians have suggested figures of between 5000 and 13,000 for Harold's army at Hastings, but most agree on a range of between 7000 and 8000 English troops. These men would have comprised a mix of the
fyrd (militia mainly composed of foot soldiers) and the
housecarls (nobleman's personal troops), who usually also fought on foot. The main difference between the two types was in their armour; the
housecarls used better protecting armour than the
fyrd. The English army does not appear to have had many archers, although some were present. Although the numbers on each side were probably about equal, William had both cavalry and infantry, including many archers, while Harold had only foot soldiers and few archers. The English soldiers formed up as a
shield wall along the ridge, and were at first so effective that William's army was thrown back with heavy casualties. Some of William's Breton troops panicked and fled, and some of the English troops appear to have pursued the fleeing Bretons. Norman cavalry then attacked and killed the pursuing troops. While the Bretons were fleeing, rumours swept the Norman forces that William had been killed, but William rallied his troops. Twice more the Normans made
feigned withdrawals, tempting the English into pursuit and allowing the Norman cavalry to attack them repeatedly. The available sources are more confused about events in the afternoon, but it appears that the decisive event was the death of Harold, about which different stories are told.
William of Jumieges claims that Harold was killed by William. The
Bayeux Tapestry has been claimed to show Harold's death by an arrow to the eye, but this may be a later reworking of the tapestry to conform to 12th-century stories that Harold had died from an arrow wound to the head. Other sources state that no one knew how Harold died because the press of battle was so tight around the king that the soldiers could not see who struck the fatal blow. William of Poitiers gives no details about Harold's death.
Aftermath The day after the battle, Harold's body was identified, either by his armour or marks on his body. The bodies of the English dead, which included some of Harold's brothers and his
housecarls, were left on the battlefield,
Gytha, Harold's mother, offered William the weight of her son's body in gold for its custody, but her offer was refused. William ordered that Harold's body be thrown into the sea, but whether that took place is unclear.
Waltham Abbey, which had been founded by Harold, later claimed that his body had been buried there secretly. Later legends claimed that Harold did not die at Hastings but escaped and became a hermit at Chester. William therefore advanced, marching around the coast of
Kent to London. He defeated an English force that
attacked him at Southwark, but being unable to storm
London Bridge, he sought to reach the capital by a more circuitous route. William moved up the
Thames valley to cross the river at
Wallingford, Berkshire; while there he received the submission of Stigand. He then travelled north-east along the
Chilterns, before advancing towards London from the north-west, fighting further engagements against forces from the city. Having failed to muster an effective military response, Edgar's leading supporters lost their nerve, and the English leaders surrendered to William at
Berkhamsted, Hertfordshire. William was
acclaimed King of England and crowned by Ealdred on 25 December 1066, in
Westminster Abbey. ==English resistance==
