For much of the time (1922-1930) Brig. Gen. John H. Russell was commander (and later High Commissioner). Before that time, a group of military and civilian administrators reported directly to Washington.
The first detachment of marines (1915) was under the command of Major Smedley Butler, who drove the Cacos out of Port au Prince.
