Ike's Spies: Eisenhower and the Espionage Establishment

As Ambrose makes clear, Eisenhower was introduced to the world of intelligence by Winston Churchill and rapidly became fascinated with it. His chief intelligence officer Kenneth Strong, a British General, kept him remarkably informed throughout the Second World War. Ambrose argues, and he is almost certainly right, that only the combination of great intelligence about the Germans and the most successful deception plan in history made the invasion of France possible in 1944. He also notes that deception had also been brilliantly used in 1943 to convince the Germans that the allies were going to invade Sardinia or Greece rather than Sicily. The result was a reallocation of German forces to the wrong places, which weakened their forces in Sicily.

There are a lot of lessons in this book for our generation. Eisenhower valued technology and took risks to develop it. He knew how to undertake successful covert operations. For anyone who would understand the uses of intelligence in the modern world, this is a useful book.
