The Battle of Waterloo is remembered as a triumph of English redcoats, but this episode makes the case that the army under the Duke of Wellington was overwhelmingly not English at all, drawing on Dutch, Belgian, and German troops alongside Napoleon's veterans. The film covers the climactic clash between Wellington and Napoleon Bonaparte, tracing the collapse of the French Imperial Guard, the pressure of Blucher's Prussian reinforcements arriving late in the day, and the terrain around the farmhouses of Hougoumont and La Haye Sainte that shaped how the battle actually unfolded. Historians walk the ground where the fighting happened, using maps, battlefield reconstructions, and period accounts to explain troop movements and command decisions on both sides. As the second episode in the Waterloo Warriors series, it builds on the buildup to the battle to focus squarely on the day's fighting itself, treating the outcome not as inevitable but as a near-run result decided by exhausted, multinational armies pushed to their limits.
