Why can't the AI naval invade?

[ImAdrian]

I'm an Irish nation, fighting against England with Castille as an ally. We have total naval supremacy, blockading all of England.
Castille has like 20 transports and 45k troops. Aragon (their PU) has another 10-15 transports and 25k troops.
England has 25k troops.

No-one is trying to land on the british isles..... i had to white peace because I couldn't 1v1 england alone... Should I just assume all my allies will be useless in the future?

The thing is, I have land on the main island, they dont have to disembark in hostile territory....

If you have stronger navy just trap english army in one of the northern islands when they cross strait to resiege or fight your army.
If possible you can try allowing smaller stacks to Ulster and blocking strait to kill them

To me it sounds like he might have already united the island and that he is fighting an offensive war.

@Commonblob I think so too but by this point England usually has control over Hebrides and Orkney. If all of them belong to someone else he can use military access and lure the English army there, later trap it with his navy. Straits are very powerful if you have the stronger navy

try getting military access to france, putting your transport fleet in the channel, and click "allow allies to board". That used to make the AI happy, if you have a bunch of transports.

Set Castiles goal to take London and set Aragon's to take the Northumberland fort or the Wales fort. See if that gets them moving. Make Pale the war goal and you should be able to cut them off easy if you have naval blockade. That's should get you a ticking warscore, maybe in the 40% range? Then take London in peace deal if you can.

I feel 1.33 has ruined the last improvements to naval invasions...

Yea, thank you. For this specific scenario I used your advice... (well sort of). I trapped them in Ireland, because i took the other side of the strait from Scotland. They did siege all my land in Ireland and I ended the war with 20/20 war exhaustion, but I managed to beat England alone with half the troops

Still, I made the thread mostly because I was stunned to see my allies not moving at all when we control the sea. I kept hearing about all the latest AI improvements

Yep I just had a fun experience with GB as an ally in a war against Spain. They sat on their island for two whole war's and made peace while surrendering French Lands back to France despite me starting to occupy Aragon...

I guess it's back to England being a useless ally for now.

I know that pain and I wish it would be possible for AI to help with the invasions. This strategy is only workaround, not the sollution.

I saw France land 28k troops later against England in that same game (in a war unrelated to me).
Maybe its because they had 28 transports and could move them all in 1 go ? So i guess the problem is the AI won't try it unless they have a clear advantage with 1 single troop transport. Not accounting for any other allies or subjects, just their own strength.

 

[necro84]

I'm not sure. In some games I tried to force Byzantium, Aragon or other vassals/allies to take Crete, Rhodes or Cyprus. Provinces had 1-2k troops and they wouldn't do it. The same situation is with Socotra - I usually fight two wars vs Mahra because I don't have the navy and my vassals can't land. In the first war I take only the island, in second I take Arabian provinces so I don't have problems with separatists there.
