Answer:
A. Abraham Lincoln was elected president of the United States
He made the wrong decision, in my opinion, but that’s more of an opinion type thing, but I think he did because of his actions during the revolutionary war, which is, he led troops from Great Britain and loyalist to the throne, he was against American colonist who are fighting to gain their independence from Great Britain. Grant was also perhaps falsely accused of committing war crimes, for which she received no punishment.
