     <History>The Britons were one of the last European peoples to use two-horse chariots in combat. They had two iron-rimmed wheels and a flat riding platform that typically carried a driver and a warrior. Useless as shock weapons against tightly packed troops, they were useful for running down individual soldiers and as a stable mount to launch javelins from. The heads of defeated opponents often adorned the chassis to show the warrior's prowess.</History>

     <History>In Gaul we know of heavy cavalry, possibly predecessors to later knights. They used a Celtic lance overhand, a good shield, and wore good armor. Vercingetorix was famous for having a number of them, but their use long precedes him. Heavy Celtic horsemen are found in graves as early as the 600s, with scale coats. Later, with the advent of mail, their armor would largely change to this. They would be experienced, aristocratic or noblemen, or their retainers equipped in kind. Each man would probably have several personal attendants. Some would be powerful noblemen, such as chiefs and kings. In battle, they would be on par with much of the best heavy cavalry in western Europe, due to superior armor, such as mail armor with additional layers of mail over the vital organs, weapons such as high-quality iron spearheads, swords, and a thong of javelins, giving them versatility, and years of experience and training. Their historical use saw them capable of breaking even well-defended positions, or acting to great effect in flanking manuevers.</History>

     <History>The sword among Celts varies in reputation and commonality. Shortswords, essentially truly just long, broad-bladed daggers, were common, but cheaply made, and most likely the swords refered to as bending after a hard strike, and needing bent back into place. The iron construction of longswords, such as used here, was greatly superior, but also much more expensive. The longsword was primarily a weapon of aristocracy and experienced professional soldiers, who could either afford the weapon, have it made for them by their lord as a reward for service, passed down to them by family, or looted from the field.</History>
