The American Civil War was a pretty big deal, happening from 1861 to 1865. It was fought between the Union (also known as the North) and the Confederacy (also known as the South). The main issue at hand was slavery and states’ rights. The Union ended up victorious, and slavery was abolished as a result.
But it was a brutal war, with an estimated 620,000 to 750,000 soldiers losing their lives. It’s considered one of the bloodiest conflicts in American history and had a huge impact on America’s future. So, finding contemporary sources like this is like striking gold for a historian; they’re priceless.
