Favourite D-Day-related AH texts

Again, guys, commemorating the 60th anniversary of D-Day, what would you guys list as your favourite D-Day-related AH ? Mine would definitely have DISASTER AT D-DAY by Peter Tsouras, despite its flaws, and the article by Stephen Ambrose in Robert Cowley's 1st WHAT IF book.
 
Second your books,Melvin. Good reads. Don't know though how Rommel was able to wreak a lot of damage. What would've happened if Rommel went after one of the British zones? :) ;)
