After graduating from West Point in 1892, Charles Pelot Summerall (1867–1955) launched a distinguished military career, fighting Filipino insurgents in 1899 and Boxers in China in 1900. His remarkable service included brigade, division, and corps commands in World War I; duty as chief of staff of the U.S. Army from 1926 to 1930; and presidency of the Citadel for twenty years, where he was instrumental in establishing the school’s national reputation. Previously available only in the Citadel’s archives, Summerall’s memoir offers an eyewitness account of a formative period in U.S. Army history. Edited and annotated by Timothy K. Nenninger, the memoir documents critical moments in American military history and details Summerall’s personal life, from his impoverished childhood in Florida to his retirement from the Citadel in 1953. From the perspective of both a soldier and a general, Summerall describes how the very nature of war changed irrevocably during his lifetime.
