Definition
The Board of Ordnance was a historical British administrative body headquartered within the Tower of London. It was responsible for superintending and disposing of all arms, instruments, and materiel of war — both naval and land-based — across the magazines, garrisons, and forts of Great Britain. The Board operated in two distinct branches: a civil branch and a military branch. It functioned as the crown's principal agency for the procurement, storage, and distribution of military equipment and munitions.
The Board was formally reconstituted under 4 & 5 Will. IV c. 24 (1834), which defined its dual structure. It was subsequently abolished by 18 & 19 Vict. c. 117 (1855), when its powers, duties, and functions were transferred — principally to the Secretary of State for War, as part of the broader reorganization of British military administration following the administrative failures exposed by the Crimean War.
The phrase "of Ordnance" as it appears in legal dictionaries is therefore a fragment of the office title: the Board of Ordnance, or offices and officers deriving authority from that Board.
Common Confusion
Researchers encountering "of Ordnance" in historical legal sources should not conflate this term with ordnance as a category of law (municipal ordinances) or with the modern military usage of ordnance as a generic noun for munitions and explosive weapons. The legal dictionaries use "of Ordnance" strictly in reference to the institutional body — the Board — and its derived offices, officers, and legal authorities. A document referencing "the Surveyor of Ordnance" or "the Clerk of Ordnance," for example, refers to named offices within this administrative structure, not to a function related to local legislation or weapons management in the contemporary sense.
Why It Matters in Research
Researchers working in British constitutional history, military law, or the administrative history of the Crown will encounter references to the Board of Ordnance and its officers in a wide range of documentary contexts: land grants and conveyances of Crown property, contracts for military supply, garrison administration records, and parliamentary debates. The Board's long history — stretching from the medieval period through its abolition in 1855 — means its legal footprint is substantial and temporally variable.
Several traps exist for the unwary researcher. First, the phrase "of Ordnance" in older documents may denote an officer's title rather than a subject matter, which affects how the document should be indexed and interpreted. Second, the 1855 abolition is a hard terminus: any legal instrument or authority purporting to derive from the Board after that date is either transitional (under 18 & 19 Vict. c. 117) or erroneous. Third, the transfer of powers in 1855 was not a clean assignment to a single successor — functions were distributed across the War Office and related departments — so tracing a specific legal authority forward requires attention to which function is at issue.
For American researchers, the Board of Ordnance has limited direct relevance, but analogous structures existed in colonial and early federal contexts. The Continental Congress established its own Board of War and Ordnance in 1776, and the early United States Army's Ordnance Department (established permanently in 1812) drew on similar organizational concepts. Researchers conflating American and British usage should be cautious: the legal and administrative frameworks were parallel in structure but entirely distinct in authority.
Historical Dictionary Support
Rapalje & Lawrence and Bouvier's Law Dictionary are in close agreement on the substance of this entry — both reproduce nearly identical language describing the Board's location, function, and dual civil-military structure, and both cite the same statutory authority (4 & 5 Will. IV c. 24). This convergence is unsurprising, as Bouvier's entries on British administrative offices frequently drew on English sources, and Rapalje & Lawrence similarly followed established English legal lexicography.
Both entries are, however, incomplete as preserved. Each breaks off mid-sentence at the point of describing the transfer of powers under 18 & 19 Vict. c. 117, which is a significant gap: the 1855 abolition and transfer is precisely what gives the entry its modern relevance as a terminal event. Researchers relying solely on these dictionary entries will not learn where the Board's powers went, which requires consulting the statute directly or supplementary administrative histories.
Neither dictionary addresses the Board's pre-statutory history, which was substantial. The Board of Ordnance existed in recognizable form from at least the late fifteenth century, and its officers — the Master-General, the Lieutenant-General, the Surveyor-General, the Clerk of Ordnance, and others — appear in legal instruments well before any of the statutory codifications cited here. Historical dictionaries of this period characteristically focused on the statutory present rather than the institutional past, leaving the deeper history to specialized treatises.
Jurisdictional Note
This term is specific to English and British law and administration. It has no direct counterpart in American federal or state law, though analogous military supply and armaments functions exist under different institutional names. Researchers in Scottish, Irish, or colonial legal records may encounter the Board's authority where imperial military administration overlapped with local governance.
