In the bitter winter of 1429, during the grueling Siege of Orléans, a massive French and Scottish force intercepted a modest English supply convoy. The ensuing clash should have been an easy victory for the attackers. Instead, it went down in history as the Battle of the Herrings. The English defenders famously barricaded themselves behind hundreds of wagons filled with salted fish, using the barrels of preserved food to shatter the cavalry charge. This book delves into the absurdity and brutal reality of medieval military logistics. It strips away the romanticized myths of knights in shining armor to focus on the terrifying struggle of keeping thousands of men fed during a winter siege. The narrative uncovers how a simple supply run of Lenten provisions dictated the tactical movements of empires and inadvertently set the stage for Joan of Arc's miraculous arrival. Through the lens of this peculiar battle, readers gain a visceral understanding of the Hundred Years' War. Discover how terrain, weather, and barrels of pickled fish were often more decisive than the sharpest swords and greatest military minds.
