Chronicle of Walter of Guisborough
A canon regular of the Augustinian Guisborough Priory, Yorkshire, formerly known as The Chronicle of Walter of Hemingburgh, describes the period from 1066 to 1346. Before 1274 the Chronicle is based on other works. Thereafter, the Chronicle is original, and a remarkable source for the events of the time. This book provides a translation of the Chronicle from that date. The Latin source for our translation is the 1849 work edited by Hans Claude Hamilton. Hamilton, in his preface, says: 'In the present work we behold perhaps one of the finest samples of our early chronicles, both as regards the value of the events recorded, and the correctness with which they are detailed; Nor will the pleasing style of composition be lightly passed over by those capable of seeing reflected from it the tokens of a vigorous and cultivated mind, and a favourable specimen of the learning and taste of the age in which it was framed.'

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.
