Dion Williams

Brigadier General Dion Williams (December 15, 1869 – December 11, 1952) was an officer in the United States Marine Corps. He was the sixth assistant commandant of the Marine Corps from August 1, 1925 – July 1, 1928. During his early career, Williams pioneered the first conceptual study of amphibious reconnaissance in the United States and becoming one of the strongest advocates in having the Marine Corps assume the amphibious, expeditionary role. During his career, he fought guerrillas in the Philippines and Dominican Republic during the Spanish–American War. Williams is credited in the persuasion of Admiral Dewey in 1907 to assert Congress that "a force of 5,000 Marines with a Fleet" would have ensued the Philippine–American War following the Spanish defeat. This 'force' was the first of the doctrinal sequence of the establishment of the Advanced Base Force, its titulage American Expeditionary Force and subsequently its modern namesake, Fleet Marine Force. Williams retired from the Marine Corps in 1934, spending the rest of his life in Maryland.
