I'm just a little confused about this translation my book gave me. My book said "Litteris victoriam nuntiant" means they report the victory by means of a letter. Wouldn't this be they report the victory by means of letters? Am I incorrect or is the book? Thank you for clarifying this.

Yes, letters would be correct.
