Won's execute action

[Shawmut]

I am in Great War, turn 22. When I maneuver to commit an action - attack, I am getting no indication on my 'right click.
I can move a unit 'single' or 'group' per right click OK. It's just not allowing an attack. I've read again your scenario - looking for caveats of cease-fires or some indication of activity suspension, but found none.
Please advise.[&o]
Thank you.

If no attack button is available then either you've used up all your movement for that turn meaning no attack is available or your attacking into a hex that doesn't allow it i.e. river marsh etc. I don't know the specific scenario so I hope this helps.

turn 22 should be christmas truth?

=> cease fire! (for one round)
