An Honest Documentary About the Italian Campaign.
"The Story of G.I. Joe" is about as good a treatment of the troops that we're liable to get but it's a bottom-up point of view. The most honest treatment of this horrifying and fruitless campaign is in a documentary from the History Channel called "Up the Boody Boot." You can buy it from places like Amazon.com but it's only available on VHS and isn't listed on IMDB.com for some reason. (It's about two hours, minus commercial time.)
The documentary, narrated by Fritz Weaver, doesn't pull any punches. It names names, gives credit where it's due, and faults openly some of the Allied commanders, chiefly Mark Clark and Gen. Alexander. It's pretty brutal and includes shots of Allied dead, their faces obscured.
The focus is on the landings at Anzio, where my Uncle Florian was hit in the spine, at what came to be called the Battle of the Caves, and become a paraplegic. Another old friend, now aged, spent a year in hospital and almost lost his leg. James Arness of "Gunsmoke" fame was also on the beach.
I can't recommend the documentary highly enough for anyone who wants an analysis of the Italian campaign rather than a flag-waving tribute to men who were unquestionably brave but misused.
