Adam Murimuth's Continuation and Robert of Avesbury’s 'The Wonderful Deeds of King Edward III'

This volume brings together two of the most important contemporary chronicles for the reign of Edward III and the opening phases of the Hundred Years’ War. Written in Latin by English clerical observers, these texts provide a vivid and authoritative window into the political, diplomatic, and military history of fourteenth-century England and its continental ambitions. Adam Murimuth Continuatio's Chronicarum continues an earlier chronicle into the mid-fourteenth century, offering concise but valuable notices on royal policy, foreign relations, and ecclesiastical affairs. Its annalistic structure makes it especially useful for establishing chronology and tracing the development of events year by year. Complementing it, Robert of Avesbury’s De gestis mirabilibus regis Edwardi tertii is a rich documentary chronicle preserving letters, treaties, and official records alongside narrative passages. It is an indispensable source for understanding Edward III’s claim to the French crown, the conduct of war, and the mechanisms of medieval diplomacy. Together, these works offer scholars, students, and enthusiasts a reliable and unembellished account of a transformative period in English and European history. Essential for anyone interested in medieval chronicles, the Hundred Years’ War, or the reign of Edward III.

History of the Dukes of Normandy by William of Jumieges. So then, to the aforementioned Robert, Count of Flanders, Henry, king of the Saxons and emperor of the Romans, granted the County of Cambrai, and Robert did homage to him for it. This Robert begot two sons, Robert and Philip. Robert, who was called the Jerusalemite because he was present when Jerusalem was taken by the Christians, begot Baldwin, who succeeded him. But Baldwin died from a wound that he had received in a certain battle near the castle of Auc in Normandy. After him, Charles his kinsman succeeded. And when this Charles was treacherously killed, as has already been said, [her former husband] William [aged 25], the son of Robert, Duke of Normandy, received the county of Flanders, as stated above. But he lived only a short time afterward, for while assaulting a certain town he was struck by a mortal wound. He died on the sixth day before the Kalends of August [27th July], in the year of the Lord 1128¹. He was buried in the church of Saint Bertin the Confessor, and Thierry [aged 29] of Alsace, a kinsman of the preceding counts, succeeded him. To this Thierry, Henry, king of the English, gave in marriage the sister [Sibylla²] of Geoffrey Martel, Count of Anjou.

Igitur prædicto Roberto comiti Flandriæ Henricus rex Saxonum et imperator Romanorum, dedit comiD talum Cameracensem et ipse fecit ei inde fidelitatem. Genuit autem idem Robertus duos filios, Robertum et Philippum. Robertus vero Hierosolymitanus cognominatus, quia interfuit, dum Hierusalem a Christianis caperetur, genuit Balduinum qui ei successit. Eodem vero Balduino mortuo ex vulnere, quod in conflicta quodam apud Aucum castrum quoddam Northmanniæ acceperat, Carolus cognatus ipsius ei successit Quo per traditionem occiso, sicut jam dictum est, cumdem comitatum Flandriæ, sicut superius diximus, Willelmus filius Roberti ducis Northmanniæ habuit. Sed parvo tempore supervixit, in cujusdam oppidi assultu appetitus lethali vulnere. Decessit vero 6 Kal. Aug. anno ab incarnatione Domini 1188. Sepultus est autem in ecclesia Sancti Bertini confessoris et successit ei Terricus de Avseis, congnatus præcedentium comitum. Huic Henricus rex Anglorum copulavit sororem Gaufridi Martelli comitis Andegavorum.

His Chronicle describes the events of the period 1303-1356: Gaveston, Bannockburn, Boroughbridge, the murder of King Edward II, the Scottish Wars, Sluys, Crécy, the Black Death, Winchelsea and Poitiers. To quote Herbert Bruce 'it possesses a vigorous and characteristic style, and its value for particular events between 1303 and 1356 has been recognised by its editor and by subsequent writers'. The book provides remarkable detail about the events it describes. Baker's text has been augmented with hundreds of notes, including extracts from other contemporary chronicles, such as the Annales Londonienses, Annales Paulini, Murimuth, Lanercost, Avesbury, Guisborough and Froissart to enrich the reader's understanding.
