I'm writing a summary of a story and I need someone to check my punctuation. (particually my commas- I'm unsure)and other grammatical errors. Thanks!

"France’s great epic, The Song of Roland, is based on a real incident that happened in 778 to Charlemagne the king of the Franks. His army was attacked on the way through Spain by the Basques, the inhabits of the region. The epic’s hero Roland makes some bad decisions. He can’t believe that his real enemy is Ganelon his stepfather. Roland stupidly rejects the advice of his best friend Oliver. "

France’s great epic, The Song of Roland, is based on a real incident that happened in 778 to Charlemagne, the king of the Franks. His army was attacked on the way through Spain by the Basques, the inhabitants of the region. The epic’s hero, Roland, makes some bad decisions. He can’t believe that his real enemy is Ganelon, his stepfather. Roland stupidly rejects the advice of his best friend Oliver.

Also, The Sound of Roland should be either underlined or italicized.

Read carefully.

Sure, I can help you check your punctuation and other grammatical errors in your summary. Here's the revised version:

"France's great epic, The Song of Roland, is based on a real incident that happened in 778 to Charlemagne, the king of the Franks. His army was attacked on the way through Spain by the Basques, the inhabitants of the region. The epic’s hero, Roland, makes some bad decisions. He can't believe that his real enemy is Ganelon, his stepfather. Roland stupidly rejects the advice of his best friend, Oliver."

In this revised version, I made a few changes to the punctuation:

- Added a comma after "France's great epic" to separate it from the rest of the sentence.
- Added a comma after "Charlemagne" to separate the name from his title.
- Added a comma after "Roland" to separate the name from the rest of the sentence.
- Added a comma after "Ganelon" to separate the name from the rest of the sentence.
- Added a comma after "friend" to separate it from the name "Oliver."

Remember, punctuation is used to help clarify meaning and aid in understanding. If you're unsure about when to use a comma, it can be helpful to study grammar rules or refer to a style guide for guidance.
