We have excellent sources of First Crusade or the successful expedition of 1096–1099. There are a number of crusade chronicles, some composed by actual participants in the expedition. Among these eyewitnesses was an anonymous writer, probably a Norman cleric from southern Italy. His "Gesta Francorum" (Deeds of the Franks), in (1100/1101), strongly partial to the Norman prince Bohemond (1050/1058–1111), was widely employed as a source by other authors. Among the “crusader chroniclers” was also a chaplain named Raymond of Aguilers, who sometime between 1099 and 1105 composed a "Historia francorum qui ceperunt Hierusalem" (History of the Franks who conquered Jerusalem) completely from the perspective of Provence. The already-familiar Fulcher of Chartres should also be mentioned in this context.
These one-sided eyewitness reports can be supplemented with the works of authors who did not actually take part in the expedition, but rather compiled their own impressions from written and oral sources. We have already encountered two of these, Robert of Rheims and Baldric of Dol. Other important sources of this sort are Guibert of Nogent (d. 1124) source "Dei gesta per francos", completed in (1109), and the work of the educated Norman knight Radulfus (Raoul) of Caen, who was in the service of the Norman prince Tancred and honored his lord in the "Gesta Tancredi" of 1112. Scholars for a long time unjustly discounted the six-book crusade chronicle of Albert, probably a cleric from Aachen. Albert of Aachen’s anecdote-filled account is the only one composed without reliance on the anonymous Gesta Francorum and gives a perspective significantly different from that of the French chroniclers. He writes favorably of Godfrey of Bouillon, within whose duchy Aachen lay, and Albert’s informants for the most part were members of Godfrey’s force. Besides these various texts we have about twenty letters written by participants in the crusade. These are outstanding sources that report first-hand on the crusaders’ troubles, wishes, and state of mind. And finally, the crusaders produced many documents before their departure. By using all these complementary and sometimes contradictory sources it is possible to create a picture of the crusade waves of 1096 to 1101.
