The Master-General of the Ordnance was an important British military position before 1855, when its duties were largely abolished. Usually held by a serving General, the Master-General of the Ordnance was responsible for all British artillery, engineers, fortifications, military supplies, and much else, and was not subordinate to the Commander in Chief, the titular head of the British military. The position was frequently a cabinet level one, especially in the late 18th and early 19th centuries.
