Mounted Combat

Characters fighting from horseback (or other strange beasts) have certain advantages and disadvantages in combat, as described below.

Mounts aren't dealt Action Cards–they act with their riders. Animals specifically noted as being trained to fight (such as warhorses) may attack any threat to their front during their riders' action. Untrained horses do not fight unless riderless, and even then usually only if cornered.
