I've noticed that, when an Ally fight a battle, during turn resolution there are battle animations but no battle report.
I believe it could be helpful and realistic to have some kind of info about the battle results...maybe not something as detailed as a normal Battle Report, to take account of fog of war...even a simple line describing who won and how many were the losses would be perfect. As it is now, it's quite hard to understand what's going on other fronts.
