Very Large World War 2 Histories

I have Max Hasting's Armageddon on my bookshelf and I plan to read it soon. On the World War 2 front, Rick Atkinson's Day of Battle is first in line, so Mr. Hastings will have to wait. I can see my Very Large History pile growing as Hastings has yet another one coming called Nemesis, the Battle for Japan 1944-45. It's UK only and the Antony Beever (Stalingrad, Fall of Berlin) review is one of those that talks about the subject matter instead of the book itself.
