During this assignment, he attended the George Washington University Law School, graduating in 1916, and was promoted to captain on 29 August of that same year.

He served most of World War I aboard the Minnesota, until she struck a mine on 29 September 1918, then being detached to Marine Barracks, Quantico, Virginia, on 14 October when she put in for repairs.

During this second tour, he compiled a seven-volume history of the Corps, but the Great Depression made printing unfeasible, to which he resorted to hand-mimeographed copies for distribution.
