Definition
A midshipman is a naval officer of the lowest commissioned or near-commissioned rank, understood to be in training for a full commission rather than occupying a permanent command position. In the context of ships of war, a midshipman's duties include transmitting and seconding the orders of superior officers and assisting in the management of the vessel and its armament. The role is functionally that of a naval cadet — not yet a fully commissioned officer, but subject to naval discipline and authority.
A passed midshipman is a midshipman who has successfully completed the required examination and stands as a candidate for promotion to the rank of lieutenant, but has not yet received that promotion.
Common Language
Modern common usage (Wiktionary): An officer of the lowest rank in several navies; especially, a trainee officer.
Historical common usage (Webster's 1913): Formerly, a kind of naval cadet whose business was to carry orders and messages between officers of the quarter-deck and forecastle, and render other required services; in the English naval service, a rank attained after serving as a naval cadet.
The common and legal meanings are largely aligned here, but legal sources add a layer the common definition omits: the midshipman's precise legal status within naval hierarchy matters for questions of authority, discipline, and liability. Whether a midshipman constitutes an "officer" in the legal sense — for purposes of courts-martial jurisdiction, statutory entitlements, or command authority — is not resolved by the ordinary descriptive meaning alone.
Why It Matters in Research
Researchers encounter "midshipman" most often in historical legal materials concerning naval courts-martial, pay and pension claims, prize law, and the scope of naval discipline statutes. The key research trap is treating the term as interchangeable with "officer" across time periods and jurisdictions. Early American naval law treated midshipmen as occupying a hybrid status — subject to officer-level discipline but not always entitled to officer-level rights or pay grades. The distinction between a midshipman and a passed midshipman carries real legal weight in historical pension and promotion disputes.
The term appears in U.S. federal case law in contexts involving statutory interpretation of naval rank classifications. U.S. v. Cook, 128 U.S. 254 (1889), cited in Black's 2nd edition, addresses questions of naval rank and is a reference point for researchers working on the legal definition of officer grades under early federal naval statutes.
In corpus research, be alert to the fact that midshipman as a legal category was substantially reorganized in the United States during the nineteenth century, particularly following the establishment of the U.S. Naval Academy in 1845. Post-Academy sources use the term differently from pre-Academy naval regulations and case law. Historical dictionary entries that cite Webster without further legal analysis — as Rapalje & Lawrence and Bouvier do — are offering a descriptive, not a technical legal, definition. They are reliable for general orientation but insufficient for resolving questions of legal status.
Historical Dictionary Support
All four source dictionaries are in close agreement on the core descriptive definition: a midshipman transmits orders, assists superior officers, and is understood to be preparing for a commission. This consensus reflects the term's relatively stable functional meaning across the era these dictionaries were compiled.
Black's 2nd edition adds the most legally useful content by distinguishing the passed midshipman and citing U.S. v. Cook, giving researchers a statutory and case-law anchor that the other sources lack. Rapalje & Lawrence and Bouvier both defer explicitly to Webster's dictionary — an unusual move that signals the compilers regarded this as more a descriptive naval term than a term requiring independent legal analysis. Researchers should treat those entries accordingly: useful for context, not authoritative on legal status questions.
What all historical sources miss: the post-Naval Academy reorganization of midshipman ranks and the evolving statutory framework governing their pay, promotion, and discipline under federal law. None of the dictionary entries engage with the administrative and regulatory law dimensions that became increasingly important through the late nineteenth and early twentieth centuries.
Jurisdictional Note
In the United States, the legal status of midshipmen is governed by federal law and Navy regulations, with no meaningful state-law dimension. British naval law uses the rank differently and has its own distinct historical trajectory; researchers using English sources should not assume equivalence with American naval legal classifications.
