@Psychronia uh.. In the LN the major who proposed the strategy indeed dead in his last stand against Olivia and that royal brat will also dead.. shot by his own underlings for being too dumb and the HQ agreed it was enemy arrow..
@Wizard_of_Oz I think one of the letdown of this series compared to The Girl Who Ate the Dead God are with the story progress more and more stupid and incompetent general appear in the Empire like their conquest until now is a lie. In the other hand almost all Kingdom's general and top branch are really competent, rational and know their shit like their lose until now is also a lie.
Also How Olivia climb her career until become major general in a little amount of time is too easy. Compared to The Girl who Ate a Dead God is in hard mode then Olivia is in easy mode
