How do you stackwipe an army ?

[RTErk]

The only thing I know is they get stackwiped when they have nowhere to retreat to but sometimes they just get stackwiped, even if you havent occupied a single province. How does this happen, what is the math here ?

AFAIK the following situations lead to a stackwipe:

• you outnumber the enemy 10:1 at the start of the battle and the enemy doesn't fill their combat width
• the enemy morale is below 0.5 and you outnumber the enemy 2:1 and the battle has lasted for less than 12 days(or maybe exactly 12)
• the enemy morale is below 0.5 at the start of the battle (in some cases this might even work if you are outnumbered 10:1)
• you kill every last enemy soldier
• you win the battle and the enemy has nowhere to retreat to(e.g. on an island or in some situations behind forts)

I'm not exactly sure about these 0.5 thresholds. It may be that 0 morale is required in some situations

Didn't the 10:1 ratio got removed (nerfed ?) in 1.30 ?

Only partialy, if enemy has less then full combatwith of units, then you stackwipe them. If they can fill combatwidth a battle will occur


With that you can stakwipe 20 stack with 200+ doomstack, but if you run into 80+ stack an battle will occur even if you had 1000 + stack marching around (a bit of multiplayer balance check)

It got nerfed. Before 1.30 you could use the 10:1 stackwipe even if the enemy filled the combat width. This nerf doesn't matter much in a normal run, but it makes it impossible to stackwipe every AI army by running around with a stack of one million men. I think some people used that to WC with mil tech 3.

The 0.5 thresholds (or whatever the exact number is) defintely works AGAINST 10:1 odds. If you have 1k in the last province the enemy can retreat to and he will is beaten and does so (of course he has to get there before the turn of month), the enemy army will be insta-crushed, had incredible luck with that as 1 single regiment stack-wiped arounf 120k Ottos (ok, they had benn beaten, but nonetheless )
