Detail from the Bayeux Tapestry, a possible depiction of Eustace II inscribed in margin above in Latin: E...TIUS, which may be the Latinised form of his name.
Eustace's wife was Gode, the sister of King Edward the Confessor of England. In 1047, Godfrey III, Duke of Lower Lorraine rebelled against the Holy Roman Emperor, Henry III, and Eustace joined the rebellion. Then or earlier, he repudiated Gode and married Godfrey's daughter Ida.[7] The next year Eustace was excommunicated by Pope Leo IX for marrying within the prohibited degree of kinship.[8][a] Eustace and Ida were both descended from Louis II of France, and just within the prohibited seventh degree. However, since not all their ancestors are known, there might have existed a closer relationship.[10] The Pope's action was possibly at the behest of Henry III. The rebellion failed, and in 1049 Eustace and Godfrey submitted to Henry III.
Eustace visited England in 1051, and was received with honour at the court of Edward the Confessor, his former brother-in-law.[11] Edward attempted to invest Eustace as castellan of a castle in Dover, which was met with resistance by the locals resulting in nearly forty deaths.[11] The brawl in which Eustace and his servants became involved with the citizens of Dover led to a serious quarrel between the king and Godwin. The latter, to whose jurisdiction the men of Dover were subject, refused to punish them.[12] His lack of respect to those in authority became the excuse for his being outlawed together with his family. They left England, but returned the next year in 1052 with a large army, aided by the Flemish.
The following years saw still further advances by Eustace's rivals and enemies. Count Baldwin of Flanders consolidated his hold over territories he had annexed to the east. In 1060 he became tutor of his nephew King Philip I of France. In contrast Eustace's stepson Walter of Mantes failed in his attempt to claim the County of Maine. He was captured by the Normans and died soon afterwards in mysterious circumstances.
Battle of Hastings
These events evidently caused a shift in Eustace's political allegiances, for he then became an important participant in the Norman Conquest of England in 1066. He fought at Hastings, although sources vary regarding the details of his conduct during the battle. The contemporary chronicler William of Poitiers wrote concerning him:
With a harsh voice he [Duke William] called to Eustace of Boulogne, who with 50 knights was turning in flight and was about to give the signal for retreat. This man came up to the Duke and said in his ear that he ought to retire since he would court death if he went forward. But at the very moment when he uttered the words Eustace was struck between the shoulders with such force that blood gushed out from his mouth and nose and half dead he only made his escape with the aid of his followers.[13]
The depiction in the Bayeux Tapestry shows a knight carrying a banner who rides up to Duke William and points excitedly with his finger towards the rear of the Norman advance. William turns his head and lifts up his visor to show his knights following him that he is still alive and determined to fight on. This conforms therefore with Eustace having somewhat lost his nerve and having urged the Duke to retreat while the Battle was at its height with the outcome still uncertain. Other sources suggest that Eustace was present with William at the Malfosse incident in the immediate aftermath of the battle, where a Saxon feigning death leapt up and attacked him, and was presumably cut down before he could reach William.
Eustace received large land grants afterwards, which suggests he contributed in other ways as well, perhaps by providing ships.
Rebellion
In the following year, probably because he was dissatisfied with his share of the spoil, he assisted the Kentishmen in an attempt to seize Dover Castle. The conspiracy failed, and Eustace was sentenced to forfeit his English fiefs. Subsequently, he was reconciled to the Conqueror, who restored a portion of the confiscated lands.[12]
Death
Eustace died circa 1087, and was succeeded by his son, Eustace III.
By his second wife, Eustace may also have had a daughter, Ida, wife of Conon, Count of Montaigu.
Eustace also had a son, Geoffrey fitz Eustace, who married Beatrice de Mandeville, daughter of Geoffrey de Mandeville. Geoffrey and Beatrice were parents of William de Boulogne and grandparents of William's son Faramus de Boulogne.
