Morale Decrease

On a regular basis, the morale base for each unit among the garrison decreases by 1. These decreases are cumulative, and remain in effect until the fortification is relieved, or until it falls. In either case, the morale of surviving troops returns to normal as soon as they are once more in complete supply.

Morale Checks

Regular morale checks reflect the debilitating effect of being out of supply. Eventually, units will become shaken, and commanders must make an effort to rally them if they wish to make sorties against the investing forces.
