Thank you. I don't know if 'she' and 'her' refer to a woman or (militarily speaking), a convoy or ship, for example.
Anyway, I think 'dead to right' means 'to have cornered' or 'to have trapped'. So, it might be 'ella (¿el enemigo?) está arrinconada, ¿y no quieres conseguirla/destruirla?
Just my opinion.
