One of the best books on WWII ever written. I highly recommend all of Cornelius Ryan’s books.
Sadly, I think the movies aren’t so good. The Longest Day being better by far (IMHO) than A Bridge Too Far.
Another Ryan book, The Last Battle, is a must read. It deals with the battle for Berlin.
From the book, A Bridge Too Far, a fantastic story is a P-51 pilot that was making repeated runs against a AAA gun, flying low over a paratroop landing zone. The AAA gun is out of sight from the paratroopers. The Mustang is hit and impacts the ground. When all the pieces come to a stop, the pilot jumps out of the largest piece and runs to a paratrooper. He demands a weapon, stating that he knows right where the bastards are at. All of his books are completely nonfiction, based on personal accounts.
I prefer the film "Bridge too Far" to "The Longest Day". I thought the latter was far too bitty.
Frost saw the take and told him that no British officer would do that lest he instill fear and panic in his men. Frost told him that he needed to walk smartly and briskly across the street.
The movie makers discarded Frost's "technical advice" fearing that no audience would find reality realistic.
