In the 15th century, the Hussites mastered using war wagons and took their creativity to another level by assembling them to make war wagon forts. Žižka was highly proud of his ingenious invention, which surprised every opponent. Harvest wagons were transformed into Hussites transport wagons which were also used as a defensive barricade and fort. All Hussite warriors were former farmers, which meant they could manoeuvre the wagons skillfully to construct a war wagon fort and create a protective wall easily anywhere, gaining an advantage over their opponents in the middle of a battlefield.
