If a province has zero food, it will enter into a state of starvation. While a province is starving, its population (peasants, military units and thieves) will die off at a rate proportional to the food deficit. Wizards are not affected. This rate is capped at 5% and will continue until the province has a value for food greater than 0.
The 5%, does it effect army out? If not, then those at home will die in place of the army out right?
