A untrained American army, with no experience, along with the Free French and British troops, who also had no real experience, goes against Rommel and von Arnim with their skilled and very experienced Axis units. The result was, as the book says, a disaster. Not a total one, but a major one. The book examines the cause of this Allied defeat, but is light on the details. A good starter book for people who wish to get into military history or World War Two history. The book gave me the feeling that the Allies were saved from total defeat, not by anything they did, but because Rommel and von Arnim could not get along and therefore could not work together.
The book shows the fine line between disaster and total destruction. So many times the Axis were so close to completely wiping out the Allies I am frankly surprised we won Africa in the end. The Allied commanders didn't get along, most didn't understand modern warfare, and, to be honest, the American soldiers were totally unprepared for combat.
Along with this book, I would suggest Patton, Montgomery, Rommel: Masters of War if you want to know more about Rommel, Montgomery, and Patton. I would also suggest Afrikakorps: Self Portrait and An Army at Dawn: The War in North Africa, 1942-1943, Volume One of the Liberation Trilogy.
