This episode offers extensive overviews of Fall Gelb, the German military plan to invade the Low Countries (Netherlands, Belgium, and Luxembourg) during World War II, which was part of the larger Battle of France. We detail the evolution of the German operational plans, from initial, uninspired proposals to the radical Manstein Plan that shifted the main thrust through the Ardennes, achieving a breakthrough at Sedan. Furthermore, we meticulously cover the Allied defensive strategies, particularly the French focus on the Dyle-Breda Line, and chronicle the invasion itself, including key battles like the breakthrough at Sedan, the ensuing race to the English Channel, and the Miracle of Dunkirk (Operation Dynamo).
