of Caen who arrived in 1108, wrote the , extant in a single manuscript and written in idiosyncratic Latin about the exploits of Tancred, Prince of Galilee. Texts such as presented a view of crusading written from a French, Benedictine and Papalist perspective which emphasised the importance of military might and attributed success and failure to God's will. The German cleric Albert of Aachen wrote the longest and most detailed account of the First Crusade and of the following twenty years, without travelling to Outremer. One advantage of his work, is that it informs on the instigation and preaching of the crusade in the Rhineland, the preacher Peter the Hermit, the People's Crusade and the massacres of the Jews in the Rhineland cities. This work provided the only significant challenge to the Papalist, northern French tradition and gained increasing importance before the end of the century, when the cosmopolitan Jerusalemite William of Tyre expanded on Albert's writing. William's Chronicon was written in Outremer using a wealth of earlier materials and became the standard historical account of the Crusades for several centuries, until being questioned by historians in the 19thcentury. The challenge presented by the sources is illustrated by two vernacular accounts of the First Crusade: Zimmern Chronicle is now thought to be a 16thcentury fake. , although composed at the end of the 12thcentury contains later additions that cannot be differentiated. The First Crusade is also evidenced in a small collection of letters from participants to the west including the Laodikeia Letter sent by the leaders of the crusade to the pope in the Autumn of 1099, from Anselm IV, archbishop of Milan, and Stephen of Blois Sources from the Outremer Fulcher missed the culminating events of the First Crusade because he accompanied Baldwin of Boulogne to Edessa. When Baldwin became king of Jerusalem in 1100, Fulcher joined him and for the next twenty-seven years wrote the best-informed account of the kingdom. Between 1114 and 1122 Walter the Chancellor documented of the wars fought by Antioch against the Turks of northern Syria in . Both texts were used by William of Tyre, whose Chronicon deals with the history of the region from Emperor Heraclius until 1184. William was translated into French and continuators' accounts are important for the end of the first kingdom of Jerusalem (1099–1187) and the 13th century.
