I am attacking a capital while it is settled as a newly joined player

In Ancient World, when I was attacking Sparta in turn 2, if a newly joined player sets Sparta as capital in turn 2, then where do my army go?
Moreover, this player appears as my ally when he suddenly joins in this turn. Then can I directly take him down after declaring war to him in the same turn? Or get my army back if I can't attack him in this turn?
Please help me, I am so confused about the operation.

Latejoiners are called when they join after the game has started and if u attack for example sparta at turn 1 when it is neutral and a player joins the next turn your units will still attack him but instead of militia sparta will get infantry and a gen if he is premium and after a player latejoins he is automatically peaced with all other players but the very next turn automatically all those peace treaties are ended unless you or he sends you or someone else and ally request
this is to prevent other players insta killing a player that latejoins btw

If I understand this correctly then if a player late joins on T2 does that does mean he/she gets INF and gen for the battle of T1 incase that player's starting country is attacked on T1?

Yeah if the selected country has militias they will turn into inf and add a gen so basically he can be attacked the turn before he late joins but not after for 1 turn until all the auto peaces get nulled
