This is a good video especially, if you have an interest in WW2/European Theater of Operations. It is a little long, but worth it. Many do not realize that during this engagement that came to be known as "TheBattle of Hurtgen Forest", the United States lost almost as many men killed from September 19th-December 16th, 1944 as it did during the entire Vietnam War. It was a meat grinder.
