What are some of the most important/major battles of the Civil War?

I am doing a presentation for school, and obviously don’t have the time to discuss every battle being that they’re about 30 of em. I want to narrow it down to about 5-8 of the major battles. Major being, biggest, turning point, changing outcome, etc. Please help, i’d appreciate anything.

Top 20 important/major civil war battles?

Of the American civil war. I’m making a mock-monopoly, so i need 22 exactly. And there are a ton of top ten lists, but pretty much no top 20 lists (that i can find, anyway). People with a lot of knowledge on the civil war, please help?? Thanks
P.S. Any idea about the amounts [...]
