Today is the sixtieth anniversary of D-Day: the date when the Allies of World War II began their invasion of France to defeat the Axis powers in Europe. It is without a doubt one of the most spectacular battles of all time, and represents probably the single greatest achievement of logistics in warfare ever. It’s been some time since topics related to WWII were at the top of my reading list, but I remember Ryan’s The Longest Day as being informative and a good read. You can look at this Amazon list for other books that might help you learn about the events surrounding June 6th, 1944.
