It remembers me of my Danish king...
In my mod the danish gets the Varangian Guard as royal unit in high and late, so it's not uncommon to see the king leading the charge into the fray... Once i started having 5+ stars kings i just used to send the king's unit along with a handful support units to capture the provinces... Those 80 varangites slew thousands enemy troops with ease, until they got killed by a massive spanish army in a last stand...
With less than 1000 men they faced 18000 spaniards which had fairly good units, including lancers and the dreaded almughavars (those guys rocks!)... After over 6000 enemy soldiers were down my king's unit was finally wiped out by a shower of javelins while fighting against some pesky crusaders. It was an epic battle, only surpassed by the head on fight against the Horde in Kazhar (yes, i like facing them the hard way, after all MHC is an easy prey of heavy AP units in the woods... obviously it wasn't the same king)
