John Page's The Siege of Rouen is an eyewitness narrative account of Henry V's siege of Normandy's capital in 1418-19. The text is unique in English verse of the fifteenth century in providing a first-hand narrative of a significant event in contemporary warfare. The poet was (if we take him at his word) present at the siege, and his narration of the event is a complex mixture of patriotism and compassion, verse chronicle and historical romance. Page's poem is a rich and sophisticated piece of work, which until recently has received little critical interest. As a historical account it is highly valuable, containing many pieces of information not found elsewhere, and comparing favourably with other contemporary sources. Associated with the Middle English 'Brut' chronicle, it also sheds light on that text's process of composition and treatment of its source material. As a literary text it possesses a clarity of style, beauty of expression, and complexity of theme that merit much greater attention. This volume constitutes the first critical edition since Herbert Huscher's 'John Page's Siege of Rouen' published in 1927. It contains an introduction with descriptions of the fourteen manuscripts in which the text is known to survive complete or in fragments, discussions of historical context, authorship, language, metre and verse form, genre, literary background, and reception. The edition includes a full collation of the extant manuscripts in the textual notes and variants, a commentary, glossary, and index of personal and place names.
