Question: The battle in which Engenulf, Lord of Laigle died was fought against which Anglo-Saxon king?

Context paragraphs:
Eadbald of Kent: Eadbald (Old English: "Ēadbald" ) was King of Kent from 616 until his death in 640.  He was the son of King Æthelberht and his wife Bertha, a daughter of the Merovingian king Charibert.  Æthelberht made Kent the dominant force in England during his reign and became the first Anglo-Saxon king to convert to Christianity from Anglo-Saxon paganism.  Eadbald's accession was a significant setback for the growth of the church, since he retained his people's paganism and did not convert to Christianity for at least a year, and perhaps for as much as eight years.  He was ultimately converted by either Laurentius or Justus, and separated from his first wife, who had been his stepmother, at the insistence of the church.  Eadbald's second wife was Emma, who may have been a Frankish princess.  She bore him two sons, Eormenred and Eorcenberht, and a daughter, Eanswith.

The Last English King: The Last English King (1997) is a historical novel by English writer Julian Rathbone.  The novel covers the time of the Battle of Hastings.  It revolves around Walt Edwinson, a housecarl of Harold Godwinson, the last Anglo-Saxon king of England.  The story starts with Walt returning to his home at Iwerne in Dorset four years after the Battle of Hastings.  He had fled England after the defeat of the Anglo-Saxons and had spent the time travelling across Europe and Asia Minor.  The story of his journey from Constantinople via Nicomedia and Nicaea to Side is then recounted in parallel with his recollections of the time before the battle, such as his accompanying Harold to William of Normandy's attack on Dinan.

Laigle family: The Laigle family is among the best known of the families that came to England in the aftermath of the Norman Conquest.  The family took its name from the town of L'Aigle.  In the ducal period of Normandy it was the site of some strategic importance as it lay on the fringe of the duchy.  The record of the 12th century chronicler Orderic Vitalis shows Engenulf, Lord of Laigle, to have been one of the very few proven companions of William the Conqueror at the Battle of Hastings in 1066.  He was the only prominent Norman noble to lose his life at the Battle of Hastings.

Anglo-Normans: The Anglo-Normans were the medieval ruling class in England, composed mainly of a combination of ethnic Anglo-Saxons and Normans, following the Norman conquest.  A small number of Normans had earlier befriended future Anglo-Saxon King of England, Edward the Confessor, during his exile in his mother's homeland of Normandy.  When he returned to England some of them went with him, and so there were Normans already settled in England prior to the conquest.  Following the death of Edward, the powerful Anglo-Saxon noble, Harold Godwinson, acceded to the English throne until his defeat by William, Duke of Normandy at the Battle of Hastings.

Trinoda necessitas: Trinoda necessitas ("three-knotted obligation" in Latin) is a term used to refer to a "threefold tax" in Anglo-Saxon times.  Subjects of an Anglo-Saxon king were required to yield three services: bridge-bote (repairing bridges and roads), burgh-bote (building and maintaining fortifications), and fyrd-bote (serving in the militia, known as the fyrd).  Rulers very rarely exempted subjects from the "trinoda necessitas", because these services were the lifeblood of an Anglo-Saxon kingdom.  After the Norman Conquest, exemptions from the "trinoda necessitas" became more common.

Harold Godwinson: Harold Godwinson (  1022  – 14 October 1066), often called Harold II, was the last Anglo-Saxon king of England.  Harold reigned from 6 January 1066 until his death at the Battle of Hastings on 14 October, fighting the Norman invaders led by William the Conqueror during the Norman conquest of England.  His death marked the end of Anglo-Saxon rule over England.

Battle of Hastings: The Battle of Hastings was fought on 14 October 1066 between the Norman-French army of William, the Duke of Normandy, and an English army under the Anglo-Saxon King Harold Godwinson, beginning the Norman conquest of England.  It took place approximately 7 mi northwest of Hastings, close to the present-day town of Battle, East Sussex, and was a decisive Norman victory.

Saint Margaret of Scotland: Saint Margaret of Scotland (c. 1045 – 16 November 1093), also known as Margaret of Wessex, was an English princess of the House of Wessex.  Margaret was sometimes called "The Pearl of Scotland".  Born in exile in the Kingdom of Hungary, she was the sister of Edgar Ætheling, the shortly reigned and uncrowned Anglo-Saxon King of England.  Margaret and her family returned to the Kingdom of England in 1057, but fled to the Kingdom of Scotland following the Norman conquest of England in 1066.  In 1070 Margaret married King Malcolm III of Scotland, becoming Queen of Scots.  She was a very pious Roman Catholic, and among many charitable works she established a ferry across the Firth of Forth in Scotland for pilgrims travelling to St Andrews in Fife, which gave the towns of South Queensferry and North Queensferry their names.  Margaret was the mother of three kings of Scotland, or four, if Edmund of Scotland, who ruled with his uncle, Donald III, is counted, and of a queen consort of England.  According to the "Vita S. Margaritae (Scotorum) Reginae" ("Life of St. Margaret, Queen (of the Scots)"), attributed to Turgot of Durham, she died at Edinburgh Castle in Edinburgh, Scotland in 1093, merely days after receiving the news of her husband's death in battle.  In 1250 Pope Innocent IV canonized her, and her remains were reinterred in a shrine in Dunfermline Abbey in Fife, Scotland.  Her relics were dispersed after the Scottish Reformation and subsequently lost.  Mary, Queen of Scots at one time owned her head, which was subsequently preserved by Jesuits in the Scottish College, Douai, France, from where it was subsequently lost during the French Revolution.

Mayor of Barnstaple: The Mayor of Barnstaple together with the Corporation long governed the historic Borough of Barnstaple, in North Devon, England.  The seat of government was the Barnstaple Guildhall.  The mayor served a term of one year and was elected annually on the Feast of the Assumption of the Virgin (15 August) by a jury of twelve.  However Barnstaple was a mesne borough and was not held by the Mayor and Corporation in chief from the king but from the feudal baron of Barnstaple, later known as the lord of the "Castle Manor" or "Castle Court".  The Corporation tried on several occasions to claim the status of a "free borough" which answered directly to the monarch and to divest itself of this overlordship, but without success.  The mayor was not recognised as such by the monarch, but merely as the bailiff of the feudal baron.  The powers of the borough were highly restricted, as was determined by an inquisition "ad quod damnum" during the reign of King Edward III (1327–1377), which from an inspection of evidence found that members of the corporation elected their mayor only by permission of the lord, legal pleas were held in a court at which the lord's steward, not the mayor, presided, that the borough was taxed by the county assessors, and that the lord held the various assizes which the burgesses claimed.  Indeed, the purported ancient royal charter supposedly granted by the Anglo-Saxon King Aethelstan (d.939) (King of the Anglo-Saxons from 924 to 927 and King of the English from 927 to 939) and held by the corporation, from which it claimed its borough status, was suspected to be a forgery.

Ancestry of the Godwins: Very little is known for certain of the ancestry of the Godwins, the family of the last Anglo-Saxon King of England, Harold II.  When King Edward the Confessor died in January 1066 his closest relative was his great-nephew, Edgar the Ætheling, but he was young and lacked powerful supporters.  Harold was the head of the most powerful family in England and Edward's brother-in-law, and he became king.  In September 1066 Harold defeated and killed King Harald Hardrada of Norway at the Battle of Stamford Bridge, and Harold was himself defeated and killed the following month by William the Conqueror at the Battle of Hastings.
