June 6th, 1944: Operation Overlord was kicked on, marking the largest invasion force that history has ever seen. Thousands of men died on this day, storming the beaches of Normany, but their sacrifices were not in vain, as a little under a year later in 1945, the war was over, and Europe was again free from tyranny (Until the Soviets started showing their true faces). My favorite books are authored by Stephen Ambrose: D-Day, Band Of Brothers, Pegasus Bridge, and many others. I know just about everyone has either seen or heard of the HBO Mini-series based on the book, but I recommend reading the book, as it is just incredibly written.
The author also helped found a tour company, that has tours based on the sites he wrote about in his books. If I could afford the money to go, I want to go on all of them ROFL.
