units totally destroyed

[Mangudai]

Under certain conditions an entire army stack can be destroyed but usually the general will reappear somewhere in friendly territory. I sort of know what is going on, but not completely. Tell me if this is right and if there are other conditions.

1) No retreat. The enemy has military control (~95%?) of all adjacent regions so retreat is impossible. However it seems, and I could be wrong, that the army will try to retreat as normal instead of fighting to the death except during a naval invasion.

2) Ships when the port they are in is captured.

3) Lack of general supplies, harsh weather, and combat cause hits. Enough hits can destroy an entire stack, but usually this won't happen over a single turn.

Had Silbey show up in Dallas the same time that the Feds took it. He bounced to Laredo just when, you guessed it, they took it. Now he's locked in Galveston for awhile.

The Gettysburg campaign is tricky for the Rebs. I lost Ewell's entire corp after a small skirmish. I think it was due to the retreat feature.

Rivers, terrain, troop type, cohesion, generals themselves all influence a units ability to retreat as well as military control. Generals can have specific traits to reduce their ability to retreat, plus abilities to improve a unit's ability to retreat.

Totally unrealistic effects are possible. In the above example a corp scattered like the wind after taking a few hundred combat losses because all the adjacent regions were under enemy control (though unoccupied).
