Barker, a British biographer (The Brontës
) and accomplished medievalist, brings an excellent synergy of academic and literary skills to this study of the 1415 British campaign in France and the battle that was its climax, around which she elaborately reconstructs the conflict's antecedents. Henry V spent years preparing the ground: asserting initially shaky authority in England, exploiting domestic strife in France and isolating the disorganized kingdom from its traditional allies. During the campaign itself, a train of artillery manned by foreign gunners supplemented the men-at-arms and the longbowmen, who were the British army's real backbone. But the French were not the vainglorious incompetents of English legend and Shakespearean drama. Many in northern France made a brave effort, often putting aside personal and political differences to stand together at Agincourt, where they came closer to success than is generally realized. Barker shows that the battle hung by a thread: French numbers against English desperation, with courage a common virtue. She also illustrates how Agincourt was decisive—not only for its consequences in France. An English defeat would have meant chaos, perhaps civil war. Destiny on both sides of the Channel turned on the outcome of St. Crispin's Day. (June 14)
