Invasion question

[cwemyss]

How long do invasions take to play out?

My troops (US) have been fighting on Sakhalin, backed up by anywhere between 2x and 5x naval superiority, for nearly a year.

I'm about to give up on maintaining a battleship sqdn in Northeast Asia, and just go blockade N Europe instead.

Its a random event. As Germany during a two-year war with France I parked a trio of obsolete battleships in South East Asia and during that time launched two colonial invasions. The first one only lasted a couple months before I took over. The second one took the better part of a year, and when I finally took over I was told the enemy was still resisting, so it could've changed hands back to France! The war ended only a couple months later though.

If I remember correctly it states in the Manual that invasions during a war can trigger and continue if your forces outnumber the enemies 4:1
