Leland “Lou” Diamond (30 May 1890 to 20 September 1951) was a noted member of the United States Marine Corps.
He fought in France during World War I, served in China during the inter-war period, and fought in the Guadalcanal campaign as a master gunnery sergeant during World War II in the 1st Marines Division, before retiring in 1945.
His nicknames include Mr. Marine and Mr. Leatherneck.
Leland Diamond was born in Bedford, Ohio. His parents, Herbert Caleb Diamond (1864-1932) and Mima Ellenor (1866-1921), were Canadians from Belleville, Ontario. His father was the youngest of the famed Diamond Brothers of the North-West Mounted Police (NWMP), who served in the Red Deer District of Alberta in the 1880s. He is descended from the Hudson River Valley Algonquin-Mohican Diamond family of the pre-American-Revolution era. His ancestors were United Empire Loyalists John Diamond (1759-1845) and Christiana Loyst (1765-1842), from Dutchess County, New York, who fled to Fredericksburgh, Ontario after the Revolution.
The “Master Gunny” was a member and frequent visitor of the Toledo, Ohio Jewish Serviceman’s USO Club sponsored by the National Jewish Welfare Board (NJWB) in 1943 as indicated by his registration card coded as a NON-JEW with a hole punched in the top left hand corner. Diamond was a practicing Episcopalian as noted in the notes of journalist Marc Parrott who was present at Master Gunny Diamond’s Episcopalian funeral services.
He enlisted in the Marine Corps in Detroit, Michigan, 25 July 1917 at the age of 27, listing as his former occupation “railroad switchman”. He was assigned Marine Service Number 98912.
World War I
As a corporal in January 1918, he shipped out from Philadelphia aboard the USS Von Steuben bound for Brest, France. He saw action with the famous 6th Marine Regiment in the battles at Chateau Thierry, Belleau Wood, the Aisne-Marne, St. Mihiel and the Meuse-Argonne. Promoted to the grade of Sergeant, he marched to the Rhine with the Army of Occupation. At war’s end, “Mr. Leatherneck” returned to America, and received an honourable discharge.
Railroading, and civilian life in general, did not suit him, and on 23 September 1921, Diamond re-enlisted.
“Mr. Marine” itched for more action and he soon got it in Shanghai, with Company M, 3rd Battalion, 4th Marine Regiment. But the Sino-Japanese controversy, in Diamond’s opinion, was “not much of a war,” and on 10 June 1933, he returned to the United States, disembarking from the USS Henderson (AP-1) at Mare Island, California. By then he was a gunnery sergeant.
Diamond returned to Shanghai with his old outfit, the 4th Marines, ten months later; was transferred to the 2nd Marines in December 1934; and returned to the States in February 1937. Two years after his promotion to master gunnery sergeant on 10 July 1939, he was assigned to the Depot of Supplies at Philadelphia to help design a new infantry pack.
World War II
Following the Japanese attack at Pearl Harbour, Diamond shipped out to Guadalcanal with Company H, 2nd Battalion, 5th Marines, 1st Marine Division, arriving at the beaches 07 August 1942. He was then 52 years old.
Though not a “spit-and-polish” Marine, Diamond proved himself an expert with both 60- and 81-mm mortars, his accurate fire being credited as the turning point of many battles on Guadalcanal. Among the many fables concerning his Guadalcanal service is the tale that he lobbed a mortar shell down the smoke stack of an off-shore Japanese cruiser. It is considered a fact, however, that he drove the cruiser from the bay with his harassing “near-misses.”
General Alexander Vandegrift, Commander of the 1st Marine Division, and later Commandant of the Marine Corps, wrote a letter of commendation that states in part:
The Commanding General takes the greatest pleasure in commending you for the outstanding performance of duty on Tulagi and Guadalcanal, British Solomon Islands, during the occupation of those Islands by the first Marine Division. As Master Gunnery Sergeant of Company “H”, Second Battalion, Fifth Marines, you performed your duties in an outstanding manner throughout the above period. On several occasions, the well-directed and well-timed fire of the Mortar Platoon under your charge was a deciding factor in halting an enemy attack and enabling friendly troops to advance against enemy positions. You deserve the highest credit in connection with maintaining the morale of the men of the Second Battalion, Fifth Marines. You were at all times cheerful, energetic and encouraging, and never more so than during those periods when the going was toughest. You brought the benefit of your long service experience and mature judgment to the younger less-experienced men of your unit and helped them in every way possible. To every man in your company, you were a counselor, an arbiter of disputes, and an ideal Marine. Your matchless loyalty and love of the Marine Corps and all it stands for are known to hundreds of officers and men of this Division and will serve as an inspiration to them on all the battlefields on which this Division may on the future be engaged. The Commandant, U.S. Marine Corps has been furnished a copy of this letter, with a request that it be made a part of your official record.
After two months on Guadalcanal, physical disabilities dictated his evacuation by air against his wishes. He was moved to the New Hebrides and later to a hospital in New Zealand, where he somehow acquired orders to board a supply ship for New Caledonia. There a friend ordered him back to Guadalcanal – the supposed location of his old outfit. Upon his arrival, however, Diamond discovered that the 1st Marine Division had shipped out to Australia, a distance of over 1,500 miles (2,400 km). Diamond made the trip, without orders, by bumming rides on planes, ships and trains.
But Diamond was destined not to see any more combat. On 01 July 1943, he disembarked from the USS Hermitage (AP-54) at San Pedro, California, and twelve days later was made an instructor at the MCRD Parris Island, South Carolina. He was transferred to Camp Lejeune on 15 June 1945, and joined the 5th Training Battalion with the same duties.
Diamond retired on November 23, 1945, and returned to his home in Toledo, Ohio.
His death at the Great Lakes, Illinois, Naval Training Centre Hospital, 20 September 1951, was followed by a funeral, with military honours, at Sylvania, Ohio. Journalist Marc Parrott notes that Diamond’s funeral service was Episcopalian. He was laid to rest at Toledo Memorial Park in Sylvania.
Actor Ward Bond portrayed Diamond in an episode of the television series Cavalcade of America entitled “The Marine Who Lived 200 years.” It aired on 01 June 1955; a copy has been located at the Marine Corps Museum.
The Filipino-American actor Lou Diamond Phillips was named after him by his father, a Marine Corps C-130 Crew Chief.
