General of the Armies John Joseph "Black Jack" Pershing was a senior United States Army officer, most famous as the commander of the American Expeditionary Force (AEF) on the Western Front in World War I, 1917–18.
“In each succeeding war there is a tendency to proclaim as something new the principles under which it is conducted. Not only those who have never studied or experienced the realities of war, but also professional soldiers frequently fall into the error. But the principles of warfare as I learned them at West Point remain unchanged.”
“No commander was ever privileged to lead a finer force; no commander ever derived greater inspiration from the performance of his troops.”
