I'm finally getting around to ordering this book today. While looking around, I did find this book on I./JG3, too bad they don't have one on JG1. Although I do have the Defenders of the Reich Series by Mombeek, so it's probably just as effective. I wonder if Defending the Reich: The History of Jagdgeschwader 1 "Oesau", also by Mombeek, is just a rewrite of those 3 smaller paperback books. I find it hard to spend ~$70 to find out, though.
