Definition
Ordnance debentures were government-issued certificates of indebtedness issued by the Board of Ordnance — the English administrative body responsible for military supplies and equipment — directing the Treasurer of that office to make payment for stores, munitions, and related military materiel. They functioned as a form of short-term public credit instrument: suppliers who provided goods or services to the Ordnance Office received these certificates in lieu of immediate cash payment, and could later present them for redemption or, in practice, transfer them to third parties at discount.
The term belongs to a specific historical context: the English military-administrative apparatus of the seventeenth through nineteenth centuries, before the Board of Ordnance was abolished in 1855 and its functions absorbed into the War Office. Ordnance debentures are therefore a closed category — they are not issued today and have no modern administrative successor.

Common Language
Modern common usage (Wiktionary): "Debenture" — a type of bond or loan certificate issued by a company or government entity, acknowledging a debt and promising repayment, typically unsecured.
Historical common usage (Webster's 1913): "Debenture" — a customhouse certificate entitling an exporter of imported goods to a drawback of duties paid on importation; also, any instrument acknowledging a debt.
The gap here is meaningful. In common usage — both modern and historical — a "debenture" is a general debt instrument, often associated with corporate borrowing or customs procedure. "Ordnance debentures" are neither corporate instruments nor customs certificates. They are a specific species of intra-governmental payment order tied to military procurement. A researcher encountering the term in a historical source and reading it through the lens of modern debenture law will likely misunderstand both its function and its legal significance.

Common Confusion
Ordnance debentures are sometimes loosely grouped with other historical government paper — exchequer bills, navy bills, victualling bills — as though they were interchangeable. They were not. Each instrument originated from a distinct administrative department (the Exchequer, the Navy Board, the Victualling Office, the Board of Ordnance), carried different redemption mechanisms, and operated within separate chains of departmental accountability. Conflating them distorts both the administrative history and any analysis of public credit practices in the period.
Additionally, researchers should not confuse "ordnance" (military weapons and supplies) with "ordinance" (a local law or regulation). The spelling distinction is consistent and important; an "ordinance debenture" would be a different and largely meaningless construction.

Why It Matters in Research
Ordnance debentures appear almost exclusively in historical sources — English public finance records, parliamentary papers, and legal treatises from roughly the seventeenth through mid-nineteenth centuries. Researchers encountering the term should situate it within the administrative history of the Board of Ordnance, not within general debenture law.
Several research traps are worth flagging. First, because the Board of Ordnance was abolished in 1855, sources written after that date may reference ordnance debentures only retrospectively, in contexts involving outstanding claims, liquidation of obligations, or historical accounting. Second, the secondary market in government paper during this period was active; ordnance debentures could be transferred and traded, which means they appear not only in government records but in private commercial correspondence, estate inventories, and chancery proceedings. Third, Bouvier's treatment is minimal — a single-sentence entry pointing toward the administrative body — which signals that American legal practice had little occasion to engage with this instrument directly. The term surfaces in American sources primarily in treatises on English public law or comparative public finance, not in domestic practice materials.
Researchers working on English military history, public credit, or the history of government contracting will find the Board of Ordnance records at The National Archives (WO series) the primary archival source. Parliamentary debates and select committee reports on public expenditure from the eighteenth and early nineteenth centuries also address these instruments in the context of reform efforts.

Historical Dictionary Support
Bouvier's Law Dictionary provides the only dictionary treatment identified in the Law Mind corpus, and it is brief: ordnance debentures are defined as bills issued by the Board of Ordnance on its treasurer for the payment of stores. Bouvier cross-references the Ordnance Office entry, suggesting he treated the instrument as ancillary to the administrative body rather than as a freestanding legal concept.
The brevity is itself informative. Bouvier's is an American dictionary, and ordnance debentures were an English governmental mechanism with no American parallel. Their inclusion at all reflects Bouvier's effort at comprehensiveness in English public law, not any suggestion of American applicability.
No competing or supplementary definition appears in the other historical dictionaries in the Law Mind corpus. Historical English legal dictionaries — such as Jacob's Law Dictionary or Tomlin's — would be the natural next reference for researchers needing expanded treatment, though those sources fall outside the present corpus.

Jurisdictional Note
Ordnance debentures were an English instrument with no recognized American counterpart. They do not appear in the law of any U.S. jurisdiction. Researchers should treat this as a term of English legal and administrative history only.
