Book vs. Web
Both the book and website describe the Battle of Gettysburg and say how it lasted for 3 days. They both say how General Lee surrendered and talks about how many people died during the battle also how many casualties had occurred.
The Slopes of War by N.A. Perez
The Slopes of War was more of a love story and was more detailed when it came to the solider's emotions during the war. The book also had more information on the Battle of Gettysburg and had maps showing where the battles took place.
The Battle of Gettysburg website
The website talks about how on the last day of the Battle, which was July 3rd, 1863, many men were casualties. This website was very plain and boring compared to the book because the website wasn't as descriptive as the book.
