Thanks for the tip!Lies! - send your army (brigade) into claimed area and leave it out there to increase your odds +0.2% - but I am not absolutely certain were there other variables that increased that rate even more like... my personal charisma impacting national focus
In my game UK and Mexico were claiming west coast with at least 50% completion bar when I joined the race ...in both cases I was way ahead of 'em within short time so I gained historical outcome.
With one unit is enough? If I join more units to the army in the claimed territory?
Thanks
