This was a very good book. I got it so that I could learn something about Pershing without listening to his (boring and long) memoirs. The book was only a 5+ hour listen and balanced his life without the detail of many tactical movements of Indians Wars, the Spanish American War, Pancho Villa's conflict or Germans in France during WWI...his career spanned those times. Best known for insisting on and maintaining unity of command during WWI of American forces, the book describes the many arrogant French and English attempts to assimilate Americans into an already unsuccessful meat grinder...and Pershings repeated repulses. So, it would seem that his contributions are logistics, command relations and officer development. Additionally, one sees the impact of generations of American military from Grant through Marshall and their impact on 20th century history. I think that I'll read some more from this series. ( )
