Negative units killed "(-5)"?

You should absolutely love getting that message. What it means is that you "stole" units from the enemy in combat. In this case, 5 units that used to be his are now yours, permanently. Did you see spells in combat such as "Enslave Mind"? That will make an enemy unit, even a commander, your slave. In case of commanders, they lose all spell-casting and leadership ability, but they are still useful as fodder. The unit may cost you upkeep, and supplies, but who cares? The unit was FREE! Rejoice, and hope for many more such Messages.
