Battle screen translation

[stars&bars]

When a battle is underway, that picture automaticaly pops up, with the CSA flag on the left & the USA flag on the right, with a half circle that changes colour from green/red during battle to one side to the other.

green = CSA
Red = USA

But what does that domination mean when it goes to one side(green/red) or the other ?

I always assumed it meant the amount of casualties inflicted or who was dominating the battle. But I have sometimes won the battle, even when, as CSA(the red portion), the USA had the majority of the circle. Its one of the things i havent seen talked about much, and clarification on it would be nice.

Thanks

green = CSA
Red = USA

Almost; green = friend; red = enemy

But what does that domination mean when it goes to one side(green/red) or the other ?

IIRC, it represents the total power of each side in the combat; if it's in the middle, they are equally powered.

I see, thanks for clearing that up for me Rafiki
