With Arms and Sorcery is a mass-combat supplement for By Blade And Spell.
It gives you rules for running battles involving lots of combatants.

2d6 <= Morale Value -> Pass
HIt -> 1d6 Damage
Each Unit has X Hit Points (corresponds to its size)
Fall below Half HP: Pass Morale or flee
Half the army destroyed or fleeing: Morale test for all units
1v1 each other with normal combat rules
