Definition
A formal phrase of pleading — rendered in Latin as *vi et armis* and in Law French as *force et armes* — historically inserted into declarations of trespass and criminal indictments to signal that the act complained of was committed with violence or armed force. The phrase did not require proof of actual weapons; it functioned as a legal signal that the defendant's conduct was wrongful, forcible, and against the peace of the sovereign. Over time it became a pleading formula largely drained of independent evidentiary significance, and modern procedural reforms have rendered it unnecessary in civil declarations, though vestiges appear in the language of older indictments.
Common Language
Modern common usage (Wiktionary): No standard entry. The phrase is not current in ordinary English.
Historical common usage (Webster's 1913): Not separately defined. The component words "force" and "arms" carry their ordinary meanings — physical power or compulsion, and weapons or military equipment.
The gap here is not between common and legal meaning but between early legal meaning and later legal meaning. In early common law, "arms" in this phrase carried its full martial sense — actual weapons, military equipment, a multitude acting in a warlike manner. By the classical pleading era, the phrase had collapsed into a formulaic recital of violence with no requirement that weapons be present or proved. A researcher encountering the phrase must determine which era of usage applies to the source at hand.
Common Confusion
FORCE AND ARMS is sometimes conflated with FORCE AND FEAR (*vi metuque*), a related but distinct doctrine. Force and arms describes the manner of a wrongful act — done violently, against the peace. Force and fear (*vis et metus*) describes the basis for avoiding a contract or other legal act extorted under duress. The two phrases often appear in close proximity in historical sources, including consecutive entries in Black's and Bouvier's, which increases the risk of conflation. They operate in entirely different legal domains: one is a pleading formula in tort and criminal law; the other is a doctrine of contract avoidance.
Why It Matters in Research
Researchers encounter this phrase almost exclusively in pre-modern sources — medieval writs, early common law treatises, and pleading manuals from the seventeenth through nineteenth centuries. Three navigational points matter:
First, the phrase is a temporal marker. When you see *vi et armis* in a pleading or indictment, you are almost certainly reading a document drafted before procedural reforms rationalized common law pleading. In England, the Common Law Procedure Act 1852 eliminated many such formal allegations. In American jurisdictions, the shift came unevenly through state procedural codes in the nineteenth century. The presence or absence of this phrase can help date or characterize a document.
Second, the phrase evolved in meaning. Burrill's is the most precise source on early usage: in the oldest law, "force and arms" implied a multitude acting with actual military-style weapons — a communal, quasi-insurrectionary connotation. Littleton and Britton use the phrase in this robust sense. By the Chitty era, the phrase had become pure formula, inserted as a matter of course in any trespass declaration regardless of whether weapons were involved. Conflating these two usages produces misreadings of early pleadings.
Third, this phrase connects to the broader corpus of trespass doctrine. The law of trespass *vi et armis* is the ancestor of modern battery, assault, and certain criminal assault statutes. Researchers tracing the lineage of those causes of action will pass through extensive historical material saturated with this phrase. Understanding it as a pleading convention rather than a substantive element of the cause of action prevents category errors.
Historical Dictionary Support
The four shelf sources are largely consistent, with meaningful variation in depth and emphasis.
Black's and Bouvier's offer nearly identical, abbreviated treatments: the phrase appears in declarations of trespass and indictments, is now unnecessary in declarations, and denotes that the act was done with violence. Both cite Chitty's *Pleadings* (2 Chit. Pl. 846, 850) and Bouvier adds Stephen's *Commentaries* (2 Steph. Com. 364). These entries are useful for confirming the phrase's procedural status in the mature common law but say nothing about its origins.
Rapalje & Lawrence add the Latin equivalent (*vi et armis*) and note that the phrase was inserted in indictments, though not absolutely necessary — a useful clarification that its omission was not fatal even in criminal pleading.
Burrill's is the most historically rich. He traces the phrase to its early law context, drawing on Britton (*c. 53*) and Littleton (*sect. 240*), and explains that "arms" originally carried its full proper sense of military equipment — not a rhetorical flourish but a description of actual armed assembly. Burrill also catalogues variant forms: *force of arms*, *force with arms*, and *armed force*, all serving the same pleading purpose. For researchers working in pre-sixteenth-century materials, Burrill's entry is the necessary starting point.
What the historical dictionaries collectively omit: none of them adequately explains the doctrinal transition — why and when the phrase lost substantive content and became mere formula. Researchers needing that transition charted should look to Milsom's historical work on trespass and the development of the forms of action.
