"Although the American contribution was only a third of the total allied effort at best, it still meant the difference between victory and prolonged trench warfare. Hence, Pershing returned home to great honor and adulation. Congress revived the special rank of General of the Armies for him, while friends encouraged the general to try politics. Unfortunately, that swamp was not for him; he sunk in up to his neck when the water was only knee deep. He stayed with the Army; and when Peyton March's term expired in 1921, moved up to Chief of Staff. Understandably, Pershing's years in that office have not been especially noted by history. His main task was to preside over a demobilized Army that Congress further depleted each year. At the end of his four years, Pershing accepted the directorship of the American Battle Monuments Commission. During that period, he compiled his war memoir, My Experiences in the World War, which was published in two volumes in 1931 and won the Pulitzer prize in history the following year. He lived until 1948, albeit in a state of increasing physical debilitation from 1941 onward. Happily, much of his character rubbed off on his surviving son Warren. When Pershing offered to visit his son at college and walk around the campus, Warren demurred on the grounds that it would be "too swank." When World War II came, Warren enlisted in the Army, went to officers candidate school, and fought in Europe, making his father quite proud."
