Danged, I am trying to locate the info in my documents regarding them. I saw it the other day...Should have stopped and copied it here then. That's what I get!
I think I picked up a copy of "Devil's Brigade" in one of those bins of DVD's at $5.
I used to have a book about them called: "The Devils' Brigade" - by Robert Adleman and Colonel George Walton. It was more of an oral history than a real history. So, I gave it to someone who wanted some books to read.
This unit was founded by Colonel Frederick and the trained in Helena, Montanna. Their first assault was the scaling of the 200-foot cliff of the Monte la Difensa in Italy, as depicted in the movie. Later they commanded a 10-mile portion of the Anzio front where their nightly patrols earned them the name Schwartzteufeln, or "Black Devils." The book seemed to tell more about their underground club they built at Anzio then the fighting they did.
Their patch is a red Arrowhead with point down and word CANADA and USA. A very desirable patch for collectors. They had a unique branch collar insignia of 2 crossed arrows forming an X.
