Marmion: A Tale of Flodden Field - Sir Walter Scott

Marmion is an epic poem in six cantos, written in emulation of the ancient Scottish minstrel style which was of such great interest to Scott. Unlike its predecessor, The Lay of the Last Minstrel, this one contains "introductions" to each canto, in the guise of poetic letters which serve the purpose of linking the ancient historical setting with Scott's contemporaneous society - a device which attracted some criticism.
The story of Lord Marmion and his arch-enemy Harold de Wilton is told with Scott's familiar swirling dark flair, combining a complex tale of intrigue, inconstancy and deception with the historical details of the Battle of Flodden Field, in which the English forces routed those of Scotland, killing the Scottish king. - Summary by Peter Tucker
