If you’ve got control of the Med’ & can keep your troops supplied by switching to their closest port
How does one do this? In my current game (Battle of France start) the entire British army is motorised so supply was a right pain because it all had to come from Alex. I got by on supplies captured from Italy (I often took provinces with 4-500 supplies and fuel for some reason, no idea what ITA AI was doing) but would have liked to have used the ports that I captured. Is it a case of setting convoys to manual and making them yourself?
