Clearly one of the greatest WW 2 books I have ever read was written by General Leslie R. Groves "Now it Can Be Told". The hands on experience of the development of the atomic bomb. The book is crammed with facts and details you will never see on Television. Also,your learn of General Groves serious and dangerous attempts of espionage in his attempts to learn and to stamp out any efforts of the Germans to produce enriched uranium.
The second greatest book, "Studka Pilot" by Hans Rudel. This book is so entertaining I could not put it down. Hans Rudel the only soldier(airman) to receive the solid gold iron cross in German history. The book is a roller coaster of adventure, all of which is true. You can see videos of him on Youtube.
The third greatest "To Hell and Back" by Audrey Murphy. Bravery beyond belief. You read in detail his version of making a last stand on a burning armoured vehicle firing away with a heavy machine gun. Further, you learn of his Nazi soldier hunt. I mean this man was a dangerous soldier.
Fourth," Marine" Sniper-93 confirm Kills by Carlos Hathcock. I am so surprised that he was not awarded the Medal of Honour for his three days of crawling through a jungle and open field on his belly so that he could eliminate a North Vietnamese General, one of his daring exploits. Mr. Hathcock had no mercy and sent many to Budda Heaven.
