William O. Darby was plucked from the infantry to form, train and lead an experimental unit along the lines of the British Commandos. Eschewing the copycat title American Commandos, he sought a name more uniquely American and decided upon Rangers, a name descendant from Roger's Rangers from the French and Indian War. Major (at the time) Darby formed the 1st Ranger Battalion and so began the legend of the famed U.S. Army Rangers in World War II.
Darby didn't survive the War but his exploits as commanding officer of the Rangers were dictated to a friend and West Point classmate, William H. Baumer, in May of 1944. Within these words Darby described the formation of the Ranger Force (the 1st, 3rd and 4th Ranger Battalions) and its contribution in North Africa, Sicily and Italy where it was virtually wiped out by a German Panzer Division near the town of Cisterna.
What Darby proved was that if highly motivated and physically fit men were trained to a razor's edge, there is nothing they could not accomplish. His experiment led to the formation of the 2nd, 5th and 6th Ranger Battalions, the first two being instrumental in the Normandy Invasion.
After many years, Baumer was successful in editing the manuscript and getting this book published. This book is an important piece of history as it was fortuitous to capture Darby's recollections before the War claimed his life. The additional comments of the men he commanded add much to commentary Darby left behind.
