The Black Eagle: Bertrand Du Guesclin, Sword of France by M. Coryn is a stirring historical novel that brings to life the legendary Breton knight who became one of France's greatest military leaders of the 14th century. Du Guesclin, known as "the Black Eagle," rose from relatively modest origins to command armies during the Hundred Years' War, earning renown for both his battlefield brilliance and his unwavering loyalty to France. Coryn's narrative traces Du Guesclin's journey from his youth in Brittany—where his courage and tenacity first set him apart—to his pivotal role in France's campaigns against the English. With vivid battle scenes, courtly intrigues, and finely drawn characters, the novel captures the drama of a tumultuous age marked by shifting alliances, dynastic rivalries, and relentless conflict. But The Black Eagle is not just a chronicle of war; it is also the story of a man of principle and determination, whose humility and fierce devotion made him beloved by soldiers and respected even by his enemies. Coryn presents Du Guesclin as both a national hero and a deeply human figure, whose victories helped shape the course of French history. Richly detailed and energetically written, The Black Eagle blends history and fiction into a compelling portrait of one of medieval Europe's most remarkable warriors. It remains an inspiring tale of honor, courage, and the enduring legacy of a knight who became the sword and shield of his country.
