Nazi Germany and civil War. Let's go.
For real. You're talking to the girl who read Gone with the Wind in 5 days at the age of 12, and then spend the next 5 weeks researching its plot holes and historical accuracies/inaccuracies.
I wrote a 22 page paper on African American troops during the Civil War backed by primary resources. It was intense. I also took a class about the social ramifications of the Civil War, and a class on the military tactics of the war before doing so as a senior thesis for my history degree. People underestimate how brutal the war was, especially battles such as Antietam, Spotsylvania Court House, and Chickamuaga, and African Americans were generally thrust right into the front lines and were specifically targeted in many of the battles they fought in.
I did most of my Nazi Germany learning under Norma Goda. He teaches at Florida now, but he's one of the foremost intelligent men on this planet on the subject. His class was mind blowing and his knowledge on the subjects surrounding the events of WW2 make me envious. 10 weeks isn't enough to tap his brain, that's for sure.
