Arnulf III, Count of Flanders
Arnulf III († 22 February 1071) a.k.a Arnulf 'the unlucky' became Count of Flanders as a minor in 1070 and until his death in 1071.
Born c. 1055, Arnulf was the eldest son of Baldwin VI, Count of Flanders and Richilde, Countess of Mons and Hainaut. On his deathbed in 1070, Baldwin VI, left Flanders to his eldest son Arnulf III and Hainaut to the next oldest son Baldwin with the provision that if either preceded the other in death, he would inherit the other's county as well. Baldwin VI further entrusted his brother Robert with the safeguard of his son Arnulf III, who was still a minor, to which Robert gave his oath of homage and solemn promise to protect his nephew. Richilde, Arnulf's mother, the dowager Countess of Flanders and de jure Countess of Hainaut, was to be regent in Flanders until Arnulf came of age.
After his father's death in 1070, his uncle Robert 'the Frisian' broke his oath and disputed the succession. Richilde appealed to King Philip I of France who summoned Robert to appear before him. Robert refused and continued his aggression against Richilde and Arnulf at which point Philip I amassed an army which he brought to Flanders. The French army was accompanied by Norman troops, probably sent by Arnulf's aunt Queen Matilda and led by William FitzOsborn. Also allied to Arnulf III was Eustace II, Count of Boulogne who raised considerable support for the young count and his mother. The two forces met at the Battle of Cassel on 22 February 1071. In that engagement Robert's forces were ultimately victorious[a] but Robert himself was captured and his forces in turn captured the Countess Richilde. Both were freed in exchange and the battle continued to its conclusion. Among the dead was Arnulf III, killed by Gerbod the Fleming, 1st Earl of Chester, possibly by accident.[b] As a result of the battle Robert claimed the countship of Flanders. The Countess Richilde and her son Baldwin returned to Hainaut but continued to instigate hostilities against Robert. As he was a minor at his death and unmarried, Arnulf III had no issue.
- The outcome of the battle itself was not a clear victory for either side, but the fact that Arnulf III was killed during the battle led to Robert's perceived victory by his recognition as Count of Flanders. See: Heather Tanner, Families, Friends, and Allies (Brill, 2004), 104.
- Gerbod the Fleming, Earl of Chester and hereditary advocate of the Abbey of Saint Bertin at Saint-Omer, Flanders, had obtained permission of William the Conqueror to return to Flanders, ostensibly to tend to his affairs there. See: C.P. Lewis, 'The Formation of the Honor of Chester, 1066-1100,' The Earldom of Chester and its Charters; A Tribute to Geoffrey Barraclough, Ed. A.T. Thacker, Journal of the Chester Archaeological Society, Chester, Vol. 71, 1991, p.39. He was at the Battle of Cassel in early 1071 and according Gilbert of Mons killed Arnulf III in battle. After realizing he had killed the rightful count of Flanders who was also the Conqueror's nephew, he fled to Rome to seek forgiveness for the sin of killing his liege lord. The Pope, Gregory VII sent him to Hugh Abbot of Cluny who permitted him to become a monk at Cluny.
