siege
Enable an agent to recognise and describe a siege, assess its changing condition and consequences, and identify which interpretations or actions require further evidence.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an agent to recognise and describe a siege, assess its changing condition and consequences, and identify which interpretations or actions require further evidence.
A siege is a sustained military operation against a defended place that restricts access, supplies or movement to compel its capitulation or enable its capture, often combining encirclement with bombardment or assault.
It can be Assess whether a reported episode meets an explicitly chosen definition of siege.; Build a dated account of the defended place, participant roles and restrictions on access.; Compare claims about containment, relief and surrender while preserving their provenance.; Flag reported civilian needs, service failures and gaps in observations for further assessment.; Track negotiated access commitments against evidence of actual passage.; Explain whether an episode remains ongoing or has ended, including unresolved classification questions..
Distinguishing features
A candidate siege has an identifiable defended place whose external access is subjected to sustained hostile restriction; an attack alone does not establish a siege.
Containment bears on the place and its occupants over time, rather than solely on a mobile force temporarily surrounded during combat.
A siege can include bombardment or assault, but those activities must be recorded separately from the evidence establishing containment.
A siege claim must specify which routes and movements are restricted; complete encirclement is a classification question rather than an automatic assumption.
Descriptions such as blockade, encirclement and siege may overlap; the model records each source's criteria instead of treating these terms as interchangeable.
Scope
+ Criteria for identifying a siege and distinguishing disputed or partial instances
+ The defended place, its occupants, surrounding forces and external connections
+ The extent, continuity and effects of hostile containment
+ Changes in the siege, negotiations, relief and termination
+ Consequences for civilians and essential services, with uncertainties and reported constraints
- The encompassing war or campaign beyond its relationship to the siege
- Technical specifications or instructions for employing weapons and siege equipment
- Fortification design except as context for identifying the defended place
- Naval or economic blockades without an established relationship to a besieged place
- Generic supply-chain models and individual medical case records
- Figurative sieges, fictional game mechanics and ordinary political isolation
Characteristics
- Classification confidence
- candidate | supported | contested | rejected Separates a reported label from an assessment supported by explicit criteria.
- Besieged place
- Referenced settlement, fortress, installation or bounded defended area, with dated boundary Establishes what is contained and prevents the episode from expanding silently to an entire region.
- Participant role
- Participant linked to dated role: besieging force | defending force | civilian population | relief actor | intermediary Roles can change, and people inside the perimeter must not all be treated as defenders.
- Containment coverage
- complete | partial | intermittent | disputed | unknown, qualified by route and movement type A perimeter description alone does not establish whether people, supplies or communications can pass.
- Episode duration
- Elapsed days with start and end uncertainty; open-ended for an ongoing episode Supports comparison while preserving disagreement over when containment began or ended.
- Access condition
- open | restricted | closed | intermittently available | unknown, per route, population or resource and observation time Distinguishes nominal access arrangements from observed passage.
- Essential-service availability
- Service-specific measure such as water volume per person per day, electricity hours per day or functioning facilities; unknown where unmeasured Makes deprivation assessable without assuming that every disruption has the same cause.
- Episode state
- forming | ongoing | temporarily interrupted | ended | uncertain Distinguishes a pause or limited opening from termination of containment.
- Termination mechanism
- withdrawal | relief | negotiated settlement | surrender | capture | mixed | disputed | unknown Records how the siege ended separately from who claims victory.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 34 questions.
Siege identity and boundaries Establishes the sense of siege being modelled and the boundaries of a particular episode.
Siege can overlap with blockade, encirclement and assault, making explicit inclusion criteria necessary.
Classification criteria
Records the definitions used to identify an episode as a siege.
Basis for siege designation
Records a source's designation, its criteria and the observations supporting or challenging that designation.
- What combination of defended place, hostile containment and persistence qualifies an episode as a siege under the adopted definition? definition
- Which sources call this episode a siege, and which use a different classification? provenance
- What evidence distinguishes this episode from an assault, blockade or temporary encirclement? boundary
Place and episode boundaries
Identifies the contained place and determines whether adjacent events belong to the same siege.
Bounded siege episode
Records dated spatial limits and continuity criteria without assuming that changing perimeters create new episodes.
- Which defended place or connected set of positions is the object of containment, and how does that boundary change? boundary
- What interruption would separate two sieges rather than mark a pause within one? definition
Participants and contained population Identifies the parties exerting or resisting containment and the people affected inside the place.
A siege involves distinct relationships between military actors, governing authorities and civilians that cannot be inferred from location alone.
Forces and authorities
Records dated roles, authority relationships and attributed objectives.
Roles and stated objectives
Separates observed participation from claims about command, responsibility and intended outcomes.
- Which actors impose containment, defend the place or seek to relieve it at each stage? boundary
- Who states each actor's objectives, and is the account a direct statement or an external interpretation? provenance
- Which authorities can credibly make or implement agreements concerning access or surrender? action
Population and movement
Describes the population inside the siege and its changing ability to move.
People within containment
Records population estimates, displacement and differentiated movement restrictions without equating residence with combatant status.
- How many people are estimated to be inside the contained area, on what date and by what method? measurement
- Which groups can enter or leave in practice, and what evidence establishes restrictions, coercion or other barriers? boundary
Containment and external access Describes how external connections are restricted and whether apparent openings provide actual access.
The defining condition of a siege is sustained containment, whose extent cannot be inferred solely from a map or announcement.
Observed containment
Records restrictions at a descriptive level across routes and types of movement.
Extent and continuity of restriction
Distinguishes physical surrounding from observed restrictions on people, goods and communications.
- Which external connections are reported restricted, for which movements and during which periods? measurement
- What evidence supports describing containment as complete, partial or intermittent? provenance
Access arrangements and delivery
Tracks announced openings, permissions and observed passage or delivery.
Promised versus realised access
Records access commitments separately from their implementation and from the adequacy of delivered assistance.
- What access was agreed or announced, by whom and for which people or goods? provenance
- What passage or delivery actually occurred, and how does it compare with the stated arrangement and assessed needs? measurement
- What further verification is needed before treating an announced opening as usable access? action
Civilian conditions and consequences Records deprivation, service disruption and harm with explicit evidential and causal limits.
Assessing a siege requires understanding conditions inside the place without assuming every observed harm was caused by containment.
Essential needs and services
Assesses reported availability and distribution of necessities within the contained area.
Availability and distribution of necessities
Records food, water, shelter, energy and healthcare conditions, distinguishing aggregate availability from access by particular groups.
- What dated measurements or observations describe access to food, water, shelter, energy and healthcare? measurement
- Which neighbourhoods or population groups face different conditions, and what evidence supports those differences? boundary
- Which reported unmet needs warrant referral for assessment or assistance, and which remain unverified? action
Harm and attribution
Separates observed consequences from explanations and formal assessments of responsibility.
Documented harm and causal limits
Records reported deaths, injuries, displacement and damage with methods, uncertainty and attributed causal accounts.
- How were reported casualties, displacement and damage counted, and what omissions or duplication may affect those counts? measurement
- What evidence connects a reported harm to containment, direct hostilities, internal distribution failures or another cause? provenance
- Which allegations or formal findings concern conduct during the siege, and who issued each assessment under which stated framework? provenance
Siege course and termination Tracks meaningful changes and establishes whether containment has actually ended.
Assaults, negotiations, temporary openings and relief attempts can change a siege without terminating it.
Phases and transitions
Builds a chronology around changes in containment and conditions inside the place.
Evidenced phase changes
Records the onset, intensification, interruption and resumption of containment as evidenced transitions.
- Which dated observations establish the onset of sustained containment rather than the beginning of nearby fighting? boundary
- Which events materially changed access, control or conditions, and how certain are their dates? measurement
Ending and residual restrictions
Separates announced endings and claimed victories from observed cessation of siege conditions.
Termination basis and outcome
Records how containment ended, competing end dates and restrictions that persisted afterward.
- What observable change supports marking the siege ended rather than temporarily interrupted? definition
- Which sources support the termination mechanism and date, and where do their accounts disagree? provenance
- Which continuing restrictions or consequences belong to occupation, blockade, displacement or recovery models after termination? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Failure modes and hazards
Recalled without web access and unsourced; every item is a lead to verify.
- Starvation, dehydration, disease and collapse of essential civilian services.
- Civilian casualties and destruction of housing, infrastructure and cultural property.
- Failure to seal supply routes, allowing the defenders to sustain resistance.
- Relief forces or defender sorties disrupting or defeating the besieging force.

- Which of these failure modes and hazards hold for the sense of siege this model covers, and on what evidence? provenance
Regional variation
Recalled without web access and unsourced; every item is a lead to verify.
- Local terrain and settlement form affect whether isolation depends on land encirclement, river control or naval forces.
- Fortification traditions and available military technology shape siege methods; differences across historical periods can be greater than differences between regions.
- Which of these regional variation hold for the sense of siege this model covers, and on what evidence? provenance
Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- blockade - A blockade principally prevents passage or exchange across an area or its approaches; a siege focuses sustained military pressure on a defended place, although the operations can overlap.
- encirclement - Encirclement describes surrounding a force or position; it becomes a siege when sustained operations isolate and pressure a defended place.
- assault - An assault attempts direct seizure through attack; it can occur within a siege but need not involve prolonged isolation.
- battle - A battle is an engagement between opposing forces; a siege is an extended operation that can contain multiple battles.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of siege this model covers, and on what evidence? provenance
What the second pass must settle
- Which historical and contemporary definitions require complete investment, and which admit partial containment or access through some routes?
- How should siege be distinguished from the encirclement of a mobile force or the blockade of an undefended settlement across different scholarly traditions?
- What evidence and continuity rules should determine the start, interruption and end of an episode when accounts conflict?
- Which measures permit useful comparison of deprivation across periods and places without imposing an unsupported universal threshold?
- Does an existing Vercy world model already own siege or a sufficiently equivalent concept, requiring this registry entry to link to it?
