Family is important. Sacrificing your sister should be the last thing on your mind. Yes, sacrifices must be made, but the least you can do is attempt to be in sorrow when saying we might need to kill your sister.
Everyone else;
I need all willing vessels to prepare to move out. Colonel Chasseur will be taking command of the rescue fleet. We will plan this, and then inform you of the time of this mission.
That will be all.
Signed,
Adelaide Roux, Marquise of Orleanais
Grande Marechal of the Royal Navy
