This is an audio CD called "In Freedom's Cause:  The Real Story of Wallace and Bruce"  from The Extraordinary Adventures of G.A. Henty.  It is an excellent audio book.  My kids have enjoyed listening several times to the story and it is a great history lesson, too.  I have 3 more brand new copies to sell.  

Can one man's faith and vision inspire a group of farmers, shepherds, and merchants to defeat the mightiest military force on the planet? William Wallace, but his undaunted courage and strength of character, forever changed the history of Scotland. His stand against oppression-despite overwhelming odds-inspired the heroic leader who would eventually gain Scotland's freedom. King Robert the Bruce. The source of Wallace's fire was his faith in God. Join an all-star cast in this epic tale of freedom. It's time to Live the Adventure®!
