Master-General of the Ordnance: History of a British Military Powerhouse
For centuries, the Master-General of the Ordnance (MGO) stood as one of the most influential positions within the British military hierarchy. From its inception in the early 15th century until its final abolition in 2013, the office managed the critical infrastructure of warfare, overseeing everything from the heaviest artillery to the smallest military supplies.
Unlike many senior roles, the MGO operated with a high degree of independence, remaining non-subordinate to the commander-in-chief of the British military. This autonomy allowed the office to function as a specialized hub for technical and logistical excellence, ensuring the British Army remained equipped for global conflict.

The Evolution of the Ordnance Office
The origins of the office trace back to the early 15th century when the Office of Armoury split from the Privy Wardrobe of the Tower of London. In 1415, King Henry V appointed Nicholas Merbury as the first Master of the Ordnance. By 1544, Henry VIII established the Office of Ordnance, which later evolved into the Board of Ordnance in 1597.
During the era before England possessed a standing army or navy, the Ordnance Office served as the nation's only permanent military department. It was a pioneer in standardization; in 1764, the office established British standard ordnance weights and measurements for artillery, creating one of the world's first technical standards for weaponry.
Administrative Structure
The Master-General sat at the top of the hierarchy, supported by key subordinates including the Lieutenant-General of the Ordnance and the Surveyor-General of the Ordnance. In the late 18th and early 19th centuries, the role often reached cabinet-level status, reflecting its importance as a political and military appointment.
Periods of Transition and Abolition
The history of the MGO is marked by several periods of discontinuation and restructuring. In 1855, the post was discontinued, and its ceremonial duties were transferred to the Commander-in-Chief of the Forces. It was revived in 1904, serving as the Fourth Military Member of the Army Board until 1938.
A significant shift occurred in 1913 when military aviation was separated from the MGO's purview. This led to the creation of the Department of Military Aeronautics, with Brigadier-General Henderson serving as its first director.
The post was abolished again in 1939 by Leslie Hore-Belisha, the Secretary of State for War, who believed the office hindered production. Consequently, responsibility for tank development was moved to the Director General of Munitions Development. The role was not reinstated until 1959.
The Final Years (1960–2013)
In its final iteration, the Master-General of the Ordnance continued to be a senior general's post. By the early 21st century, the role began to merge with modern capability management. In March 2013, the holder was given the dual title of Director Land Capability and Transformation and Master-General of the Ordnance. However, this transition was short-lived, and the post was officially eliminated in September 2013.
