Throughout the 16th Century, the Spanish had an aura of invincibility. They controlled a vast colonial empire that stretched across the Americas and the Pacific, and held considerable territories in Europe, centring on the so-called ‘Spanish Road’. The Dutch War of Independence (also known as the 80 Years' War) was a major challenge to their dominance. The Dutch army created by Maurice of Nassau used innovative new tactics and training to take the fight to Spain and in so doing created a model that would be followed by European armies for generations to come. The second in a two-part series on the Dutch armies of the 80 Years’ War, focuses on the cavalry, artillery and engineers of the evolving armies created by Maurice of Nassau. Using specially commissioned artwork and photographs of historical artefacts, it shows how the Dutch cavalry arm, artillery, and conduct of siege warfare contributed to the long struggle against the might of the Spanish Empire.
