Members of the same country (the Confederacy wasn't recognized - it doesn't count as a separate country) were making absolute war on one another. It was brother fighting brother.
I’m going with true if it’s wrong I’m sorry
5 people were killed and 6 were injured
The people that were killed were:
Crispus Attucks
Samuel Gray
James Caldwell
Samuel Maverick
Patrick Carr
Hope this helps :3
