However, he was probably not a member of the cathedral chapter, since he is not named in the listing of the Dignitaries of the Church of Our Lady of Chartres.
Fulcher was part of the entourage of Count Stephen II of Blois and Duke Robert Curthose of Normandy[2] which made its way through southern France and Italy in 1096, crossing into the Eastern Roman Empire from Bari and arriving in Constantinople in 1097, where they joined with the other armies of the First Crusade.
He travelled through Asia Minor to Marash, shortly before the army's arrival at Antioch in 1097, where he was appointed chaplain to Baldwin of Boulogne.
Although the Crusaders were routed at first, Baldwin committed his reserves and lead the counter charge himself and defeated the Muslim force.
Fulcher wrote his chronicle of the Crusade Gesta Francorum Iherusalem Peregrinantium (A history of the expedition to Jerusalem) in three books.

[5] At the earliest, Fulcher began his chronicle in the late autumn of 1100, or at the latest in the spring of 1101, in a version that has not survived but which was transmitted to Europe during his lifetime.
The third and final book reported on the life of king Baldwin II, until 1127 when there was a plague in Jerusalem, during which Fulcher apparently died.
