Was it Justified?

Civilians are just normal people, they are women and children who did not deserve to be killed. In both of Grants and Shemerans, kill civilians to get the Confederates to surrender. Yes, it is a terrible thing keeping civilians in a cave, having them live off of there own pets and animals, or burning down their houses making them evacuate their homes. Even though the Union did terrible things to the instant people it was necessary to be able to win the war, blocking off and sieging the Vicksburg it was able to cut off supplies to enter the area.
