According to the wiki http://wiki.warlight.net/index.php/Fog
if an attack occurs between two territories where you can only see the owner you can see (even if the attack fails): number of attacking armies, number of defending armies and casualties on both sides. I might be wrong and that's why i'm making this thread but to me this just seems illogical specially since it says you can only see the attack if there is an owner change, so then if the attack fails you don't see the attack but see the attacking armies? I might simply be misunderstanding something though, so if someone could clarify this I'd greatly apreaciate it. In my opinion, in that chart numbers 4, 5, 8 and 9 in owner to owner should just say "No".
