In 1099 AD, during the early days of the Spanish Reconquista, the Christian statesman and general Rodrigo Díaz de Vivar (aka El Cid) died of illness while defending Valencia from the Moors. As the battle raged and with their Hero dead, the surviving nobles inside the walls desperately needed to find some way to rally their dispirited troops for one final charge to break the siege and relieve the city.

And so, as the legend tells, Rodrigo's wife Jimena ordered the corpse of El Cid to be mounted in full battle dress on his faithful steed. The animal was then sent galloping straight at the Moorish lines. The Valencia troops, stunned out of their apathy by the seeming miracle of a resurrected El Cid, instinctively followed the warhorse into battle and won a smashing victory before anybody on either side realized the guy leading the charge wasn't actually sentient.

900 years later on Super Tuesday 2020, El Cid rode again.
