Looking over the map when I toggle on the convoy button at the top of the screen I can see the paths all convoys take for all countries. In certain situations when I try to place escorts in certain locations, I get the message that I don't have any escorts in a particular sea area. That makes me think (correct me if I'm wrong) that only certain countries are using those lanes, for example England in the early part of the war is using the North Atlantic while France is not. I can see from the little escort icons in the convoy escort dialog which country has escorts in a particular location so I'm assuming those are the only routes that are being used for a particular country. The pic below seems to tell me that England is using only the North Atlantic, South Atlantic Pan American Zone, African Coast and Caribbean Sea as convoy routes.
Is there a benefit of turning off the unused routes? I think I'm missing something?
