In 1926, when Dwight D. Eisenhower graduated first in his class from the Command and General Staff School at Fort Leavenworth, his friend George S. Patton wrote him a note of congratulations. The note was sincere and thought-provoking, telling Eisenhower, "Victory in the next war will depend on execution not plans." Eisenhower became supreme commander of the Allied Forces in Europe during WWII, dealing with planning and alliances.
