John J. Pershing

General of the Armies John Joseph Pershing (September 13, 1860 – July 15, 1948), nicknamed "Black Jack", was an American army general, educator, and founder of the Pershing Rifles. He served as the commander of the American Expeditionary Forces (AEF) during World War I from 1917 to 1920. In addition to leading the AEF to victory in World War I, Pershing served as a mentor to many in the generation of generals who led the United States Army during World War II, including George C. Marshall, Dwight D. Eisenhower, Omar Bradley, Lesley J. McNair, George S. Patton, and Douglas MacArthur.

During his command in World War I, Pershing resisted British and French demands that American forces be integrated with their armies, essentially as replacement units, and insisted that the AEF would operate as a single unit under his command, although some American units fought under British and Australian command, notably in the Battle of Hamel and the breaching of the Hindenburg Line at St Quentin Canal, precipitating the final German collapse. Pershing also allowed (at that time segregated) American all-Black units to be integrated with the French Army.
