At this point, Count Fulk IV of Anjou, whose son Geoffrey was engaged to Elias's daughter Eremburga, intervened, entering Le Mans.
[13] After William's death in 1100, Elias and Fulk took over Le Mans and expelled the Norman garrison, which surrendered after not obtaining help either from the Duke Robert Curthose or King Henry Beauclerc.
[14] In the king's conflict with Robert Curthose, he led a sizable Manceaux contingent in the campaign of 1105,[15] was present at the siege of Bayeux,[16] and was a crucial ally at the decisive Battle of Tinchebray in 1106, where he commanded the Manceaux/Breton infantry which inflicted heavy casualties on the enemy.
[20] In 1109, says Orderic Vitalis, Elias remarried to Agnes, the daughter of Duke William VIII of Aquitaine and widow of King Alfonso VI of Castile.
[20] He died on 11 July 1110 and was buried in the choir of the abbey church Notre-Dame de la Couture in Le Mans.
