Corellia, Voss might also be in trouble because Severin's death.
And in the novel it was made clear that the Empire was in big disadvantage.
corellia and especially voss were never the empires in the first place and the war pretty much wasting corellia is a solid win for the empire though a costly one. As for the novel i did say it was clear the empire was losing but 1. Novels always dramatize things, and every thing in it was basically saying we are losing until we start winning. Or in the novels owen words "unless something changes we will lose" which means as soon as something changes they will start winning. and 2. The republic lost alot while they were trying to lure the super weapon into a trap a super weapon which by the way always seemed to be in trouble in every battle it participated in. Oh and 3. The novel flat out failed to properly display the scope of each sides fighting power dumbing the numbers down by a factor of ten so why should i or any one be concerned that it displays the republic in a good light?
