Three of these, led by Fulcher of Orleans, Gottschalk and William the Carpenter respectively, failed to reach even Constantinople.
The armies of Fulcher and Gottschalk were destroyed by the Hungarians in just revenge for their excesses (June); the third, after joining in a wild Judenhetze in the towns of the valley of the Rhine, during which some io,000 Jews perished as the first-fruits of crusading zeal, was scattered to the winds in Hungary (August).
In writing his account of the First Crusade, von Sybel accordingly based himself on the three contemporary Western authorities - the Gesta Francorum, Raymond of Agiles, and Fulcher.
Fulcher of Chartres originally followed Robert of Normandy, but in October 1097 he joined Baldwin of Lorraine in his expedition to Edessa, and afterwards followed his fortunes.
A kindly old pedant, Fulcher interlards his history with much discourse on geography, zoology and sacred history.
