The initial association of Operation Overlord and Dragoon is rather interesting and is discussed in this article. August 15 is almost as critical as June 6. This is a good read.

I just finished up Rick Atkinson's excellent The Guns at Last Light, which is the last in his trilogy on the Western Front in WWII, so read all about this again, and it's contribution to the drive to the heart of Germany. The book covered D-Day through VE, so perfect background reading for our contest theme!
