Ending a turn early or how to get multi-phases

[Fulcrum]

I have been away from the game for awhile and I was curious what some people think causes premature turn endings. I know there are some ways to ensure a turn ends because I am doing them despite my best efforts to get multiple rounds out of a turn.

just curious and trying to start a conversation

The best way to get multiple rounds is using minimize loss setting. Try with this. There are several causes for premature endings: defender is ignoring losses, or attacking with ignore losses, morale check failure because the attack uses too many units with poor supply, good defensive terrain and bad scenario design: Maximum Combats per Battle settings should be 3 or 4 and sometimes this isn´t changed.
My advice: try attacking with minimal loses, strong direct support from artillery and good odds!
