About Dion Williams
Brigadier General Dion Williams (December 15, 1869 – December 11, 1952) was an officer in the United States Marine Corps. He was the 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.
Dion Williams was born in Williamsburg, Ohio on December 15, 1869.
He graduated from the United States Naval Academy where he received his early education until entering the Naval Academy and graduated on June 30, 1891.
After completing the required 2-year sea duty aboard the USS Atlanta as a midshipman for two years, he was commissioned a 2nd Lieutenant in the United States Marine Corps on July 1, 1893 and attended the School of Application before he served at the Marine Barracks, New York and the Marine Barracks, Mare Island until 1897.
He was married to Helen Mar Ames on February 20, 1895.
He participated in the Battle of Manila Bay while serving aboard the USS Baltimore' on May 1, 1898 under Admiral George Dewey. Lt. Williams landed a company of Marines at a Spanish naval arsenal yard at Cavite in the Philippine Islands, securing the naval station, and hoisting the first American flag raised over Spanish soil in the Spanish–American War.
Williams served duty at Marine Barracks, Charlston before being called out for a minor revolt in Panama 1902 to command a detachment of Marines sent to disarm Colombian troops threatening the Americans.
He continued serving two more years in various engagements of the Philippine–American War after which he served as Fleet Marine Officer of the Atlantic Fleet from 1902-04.
In March 1905, Major Williams reported to the Naval War College for two years. By 1906, Williams wrote a study, Naval Reconnaissance, Instructions for the Reconnaissance of Bays, Harbors, and Adjacent Country, which eventually became the first doctrine in United States' history concerning the pertinent missions of amphibious reconnaissance. He focused primarily on the establishment and employment of an assault force specialized in conducting preassault reconnaissance. Many of the reconnaissance ideas advanced in his studies surpassed and were eventually incorporated in the Tentative Manual for Landing Operations developed in 1934.
