Army loss while under siege

[SillySirius]

I don't know ..doing siegey stuff like digging trenches and throwing up berms as they seal off the city or get closer to the walls.Just in case they make an assault.

I know,the game doesn't simulate that.

Wear and tear from the siege.Accidents,illness,injury,the occasional raid to test the sieging army or probe for a weak spot.It just seems odd that a sieging army never losses even a single man since the biesieged losses are not from combat.

[Titus Marcellus Scato]

The game engine ensures that all armies NOT under seige get automatic full replacements for sick, injured, and discharged (old age) soldiers, just from normal supply. That's why a unit recruited 50 years ago could still be at full strength if it hadn't seen any action.

But a city under siege is cut off from normal supply, so doesn't get automatic replacements.
