Reddit reviews The Last Battle: When U.S. and German Soldiers Joined Forces in the Waning Hours of World War II in Europe

This book is a rather interesting read, too. Very well presented, and a good 2/3rds of the book is background behind the incident. How everyone wound up being there, what their reasons were (or hypotheses on what they were), etc.

Edit: ooh, and it looks like they're going to make a movie about it. That's cool. Hopefully it turns out to be a good one.

There's a book about these events:

It's a good read, just a bit short after all the built up for my taste.

You might want to look into The Last Battle, a nonfiction book about a tank unit at the end of the war. This unit found a castle that was housing political prisoners. A fanatical SS unit sieges the castle and both political prisoners and captured Wehrmacht end up taking up arms alongside the US forces. It's a pretty remarkable tale and the writing is decent.
