The use of Wagon Shields, wagons and other forms of protective barriers in war were not a new innovation by the Late Middle Ages. Nations and Kingdoms were constantly improving designs for use. One such development was The Mobile Shield Wagon System. Seen in used during The English Civil War and Jacobite Rebellions, they “appeared” at first to be common “covered” supply wagons. However, once deployed - the “covers” were removed and latched into place on either side of the wagon bed. This provided a 5 to 6 foot thick wooden barricade. Several wagons could be placed to create a mobile breastwork. Small Swivel Guns could be mounted as well as providing a platform for Crossbowmen and Musketmen. Unfortunately, Artillery would make quick work of The Wagon Shield.
