John A. Lejeune was the 13th Commandant of the Marine Corps and was the first Marine officer to command an Army Division in 1918. Who is this historical figure?

• A. John A. Lejeune
• B. Archibald Henderson
• C. Presley Neville O'Bannon
• D. Daniel Daly

Answer: (A)

John A. Lejeune is the figure described. He served as the 13th Commandant of the Marine Corps and, notably, became the first Marine officer to command an Army division in 1918 during World War I, leading a division in the American Expeditionary Forces. This milestone shows how Marine leaders could take on top-level, integrated-force command, not just Marine-only roles. The other names are renowned Marines for other reasons—Archibald Henderson as a long-serving early Commandant; Presley Neville O’Bannon noted for Derna exploits; Daniel Daly famed for Medal of Honor heroism—but none match the distinction of commanding an Army division in 1918.
