The Longest Day
Cornelius Ryan was responsible for writing what is likely the most widely-read and popular history of Operation Overlord.
More journalistic history than academic analysis, the book is none the less a very exciting and informative read.
Published first in 1959, it is still the first book turned to by Overlord enthusiasts.
Reprinted several times, The Longest Day has most recently been transformed into a beautiful coffee-table book complemented by numerous primary sources.
