Slitherine

Playing a campaign. Am told to 'evacuate' my forces on 'South east road'. Assume map is oriented to North, so can determine where SE is. But, how do you actually evacuate units?
If I'm in the wrong forum or page pls advise. I'm new to this.

Click on the button in the top left hand side of the screen where it says the message and it will display the hex where you need to move your units to, hope that helps and good luck hop you are enjoying the game
