After his proclamation as Count of Castile, Fernán González leads his men in scaling a castle wall to attack the Moors therein.

The loopholes of Manzanares are easily recognisable, and the Moors clearly get what they deserve and they are slaughtered asleep or half asleep, their only guard standing but dozing, facing way from danger.
