Attacking a unit moving to the place of the attacker?

Postby lweinreb » 19 Jul 2019, 06:10

Say Italy is in Vienna and Austria is in Budapest and Russia is in Galicia. Italy and Russia are allies, so Russia supports Italy's move from Vienna into Budapest. However, Austria wants to get Vienna back and so attempts to go there with Budapest. Given that Austria has no extra support, are they allowed to move into Vienna even though Italy was attacking them with Vienna?

No. Budapest is dislodged and may not retreat to Vienna.

If you're ever unsure of moves like this, use the Orders Solver (tab at the top...) You can copy and paste your game number in, and it populates all units' positions. From there, you simply have to enter any number of orders (you don't need to give all units orders,) and then click resolve. You will go to a page that tells you the results of each unit's order.

Hope this helps!

While not addressed in the original question, it's also helpful to note that the dislodged A Bud has no effect on the province which dislodged it, in this case Vienna.
So, if there were an army in Tyrolia, also ordered to Vienna as A Bud was, there would be no standoff in Vienna. A Tyr to Vienna would succeed (assuming no other unit other than A Bud was ordered to Vienna).

It isn't part of the rules, and I don't think I've seen it elsewhere, but I tend to think of this situation as "overwhelming force".

This is clearly a 2v1 situation. Italy is attacking with a force of 2, Austria with a force of 1. Austria's attack is therefore overwhelmed by the Italian attack (with Russian support) and therefore is routed. It can't affect the space it is trying to attack. So, as Shyvve said, should another unit be attempting to move into Vienna, it would succeed even if, without the Italian attack, Austria's order of Bud-Vie would usually bounce Tyl-Vie.

Again, not addressed, but as a contrast, if Russia didn't offer support for Vie-Bud, then Austria's order of Bud-Vie wouldn't be overwhelmed, although it also wouldn't succeed. Not being overwhelmed, it would be able to bounce a potential Tyl-Vie order.

Maybe I'm being over-complicated in thinking about this situation in this way :) It is just as easy to remember that a dislodged unit has no affect on the space from which it has been attacked. And it doesn't work if the situation is slightly changed. For instance, keeping the original orders:
ITALY: Vie-Bud
RUSSIA: Gal S Vie-Bud
but changing Austria's order to Bud-Ser, and adding a Turkish order of Con-Ser, although Austria's army is dislodged, it can bounce Con-Ser (so doesn't act as a routed army).

So, well, make it simple, I guess :)
