Battlefield and Conflict Archaeology

The forensic recovery of combatant and civilian remains from conflict sites, integrating metal-detector survey, ordnance safety protocols, and systematic excavation as demonstrated by the landmark Fromelles 2008-2010 operation.

Last updated: 10 Jun 2026

In July 1916, during the Battle of Fromelles in northern France, German forces buried approximately 1,900 Australian and British soldiers in a row of mass graves behind their lines at a site called Pheasant Wood. The graves were lost to history for nine decades. In 2009, forensic archaeologists excavated them systematically over several months, recovering 250 individuals. By 2010, using DNA, dental records, and personal effects, all but a small number had been individually identified and reinterred in a new CWGC cemetery with named headstones. It was the largest identification operation for WWI remains ever conducted, and it could not have happened without forensic archaeology as its operational backbone.

Battlefield and conflict archaeology sits at the intersection of forensic science, military history, and humanitarian law. The same methods used to investigate a present-day homicide are applied to casualties from wars fought a century ago or to victims of conflict crimes from the 1990s. The evidentiary demands are different in each context: a WWI recovery aims at identification and commemoration; a recovery from a 1990s conflict may need to meet International Criminal Court standards. But the archaeological fieldwork is largely the same.

This topic covers the integration of metal-detector survey with archaeological excavation, the in-situ recording of projectiles and ordnance evidence, the safety protocols that govern work near unexploded ordnance, and a detailed account of the Fromelles operation as the defining case study in modern conflict-casualty archaeology. The focus throughout is on the methods that allow individual identity to be reconstructed from material that has been in the ground for decades or longer.

Key terms

CWGC (Commonwealth War Graves Commission): The international organisation, established by Royal Charter in 1917, responsible for commemorating Commonwealth military casualties of the First and Second World Wars. Partners with national defence authorities on casualty recovery and identification.
Identity disc: A metal disc worn around the neck by military personnel bearing name, number, unit, and religion. In WWI British forces used two-disc systems (one red fibre, one green); recovery of a legible disc from skeletal remains is a primary identification indicator.
Unexploded ordnance (UXO): Ammunition, shells, grenades, or bombs that were deployed but did not detonate, remaining live in the ground decades or centuries after the conflict. UXO is a primary safety hazard at all conflict excavations and must be identified and cleared before safe work can proceed.
Wound track: The path of a projectile through the body at or around the time of death, reconstructable from skeletal trauma patterns and the spatial relationship between the projectile and the skeleton when found in situ.
DNA kinship matching: The process of identifying conflict casualties by comparing DNA extracted from skeletal remains to reference samples from known descendants, using STR profiles or SNP data. Used when documentary evidence (identity discs, dental records) is absent or ambiguous.
Ordnance survey grid: In the context of conflict archaeology, the systematic metal-detector transect grid laid out before excavation begins, used both to locate metallic finds and to identify UXO concentrations that define exclusion zones for initial excavation.

The Scope of Conflict-Casualty Archaeology

Three institutions, three different mandates, one shared field methodology.

Conflict-casualty archaeology in the twenty-first century is conducted by three overlapping communities. Military casualty recovery units, such as the CWGC Joint Casualty and Compassionate Centre, the US Defense POW/MIA Accounting Agency (DPAA), and the German Volksbund Deutsche Kriegsgraberfursorge (VDK), focus on WWI and WWII casualties. International forensic teams, including the International Commission on Missing Persons (ICMP) and the EAAF (Argentine Forensic Anthropology Team), work on more recent conflict victims from the 1990s Balkan wars, Latin American dictatorships, and ongoing conflicts. National archaeology units work on longer-term historical conflicts as opportunity, developer funding, or government commission allows.

The legal frameworks differ significantly. Military recovery operates under domestic defence law and international conventions on the repatriation of the war dead. International criminal tribunal recovery operates under the evidentiary standards of the ICC or ICTY. Both demand unbroken chain of custody from the ground to the laboratory and from the laboratory to the identification report or court exhibit. Both require the same foundational field standards.

Metal-Detector Survey: Integration with Archaeological Excavation

The metal detector is a pre-excavation instrument, not a treasure-hunting afterthought.

The standard model for conflict-site survey integrates metal-detector transects into the pre-excavation phase. Survey transects are laid out at 0.5-metre or 1-metre intervals across the site, walked by detector operators whose signals are flagged by assistants. Each flagged signal is given a spatial coordinate and a descriptive note (signal strength, estimated depth). The survey is complete before any ground is opened.

Pre-excavation metal-detector survey
Systematic transects at defined spacing map the distribution of metallic signals across the site. Signal concentrations that may represent burials (military equipment clustering over a defined area) are noted. UXO-specialist signals (large ferrous anomalies consistent with unexploded shells) are flagged separately and define initial exclusion zones.
UXO clearance and risk assessment
An Explosive Ordnance Disposal (EOD) specialist assesses the flagged UXO signals. Depending on signal characteristics and site history, UXO may be removed before excavation begins, or exclusion zones may be defined that constrain excavation zones. Archaeologists do not proceed in an EOD exclusion zone until clearance is confirmed.
Metal-detector integration during excavation
Once excavation begins, a metal-detector operator works ahead of or alongside the excavation team. As each context is excavated and removed, the exposed surface is swept. Signals within the burial or deposit are located with precision, and the detector guides the hand excavation toward metallic finds while the archaeologist provides the spatial and stratigraphic context.

Personal effects recovered by metal-detector survey at conflict sites carry the highest single-item identification value. A legible identity disc with a name, number, and unit is a presumptive identification that can be confirmed by DNA and dental evidence. The Fromelles excavations recovered 119 identity discs, which provided presumptive identification for 119 of the 250 recovered individuals, substantially reducing the DNA and dental workload.

Projectile and Ordnance In-situ Recording

How a bullet ends up next to a skeleton tells part of the story of how that person died.

Projectiles, shrapnel, and ordnance fragments recovered in situ within a skeletal deposit are not merely battlefield artefacts. They are evidence of cause and mechanism of death. Their position relative to the skeleton, their deformation state, and their orientation (where recoverable) contribute to the reconstruction of the wound track and in some cases allow determination of firing direction.

Standard in-situ recording follows the same principles as any in-situ find. The object is left in position until photographed with scale bar and cardinal orientation. A total-station coordinate is taken. The position relative to named skeletal elements (within the left thoracic cavity, adjacent to the left temporal bone, embedded in the right ilium) is described. The degree of deformation is noted: a jacketed bullet that has mushroomed has behaved differently from one that passed through at high velocity and retained its shape.

Unexploded Ordnance Safety Protocols

The battlefield is still armed. Safety protocols are non-negotiable.

Belgium and France collectively recover around 200 tonnes of WWI ordnance annually during agricultural and construction activity. This background rate means that any excavation on a WWI site in northern France or Belgium will encounter UXO at some stage, and archaeologists must be trained to recognise it and to respond correctly. The same principle applies across all major twentieth-century conflict zones.

Pre-site briefing: all team members receive UXO awareness training before any ground-breaking, covering the visual identification of common ordnance types, the immediate actions protocol, and the contact procedure for EOD.
Recognition: common WWI/WWII UXO includes artillery shells (cylindrical with a pointed or flat nose), stick grenades, and rifle grenades. Chemical shells have different external markings and require specialist response; they should never be handled by non-specialists.
Immediate actions: stop work, do not touch or move the object, mark the location with a visible flag, withdraw to a minimum safe distance (typically 300 metres for unexploded artillery shells as a precautionary standard), and contact EOD through the site commander.
Exclusion zones: EOD may designate a zone around a live item within which no work proceeds until the item is removed or made safe. The archaeologist records the position of the item within the site record even if EOD removes it for disposal away from the site.

At the Fromelles excavation, EOD teams were embedded with the archaeological team throughout the project. Several live items were recovered during the excavation itself, halting work temporarily in affected zones. The integration of EOD as a permanent operational component rather than an on-call resource is the standard model for conflict-era sites.

Fromelles 2008-2010: A Detailed Case Study

250 soldiers, 90 years in the ground, and a recovery that redefined the discipline.

The Battle of Fromelles on 19-20 July 1916 was the first major action by Australian forces on the Western Front, and one of the worst single days in Australian military history. Australian and British forces attacked German lines near the village of Fromelles, suffering approximately 5,500 casualties in less than 24 hours. German forces gathered their dead for burial behind their lines. Historical research by Lambis Englezos, cross-referenced with German records and aerial photographs, identified a site at Pheasant Wood as a probable burial location.

A test excavation in May 2008, led by Oxford Archaeology, confirmed the presence of human remains in at least five pits. The Australian and British governments authorised a full excavation in 2009. The project ran from May to September 2009, with 250 individuals recovered from eight mass graves. The project was distinctive in several ways: it was conducted under a transparent public protocol with full media access at designated points; it included a dedicated scientific advisory panel; and it ran a simultaneous DNA family-reference collection program, eventually gathering over 3,000 reference samples from descendants of Australian and British soldiers missing after Fromelles.

Identification used four evidence streams: DNA kinship matching, dental records (where available), identity discs, and personal effects including cap badges, religious medallions, and inscribed items. By the time the new Pheasant Wood CWGC Cemetery was dedicated in 2010, 144 of the 250 individuals had been individually named on headstones. Further identifications continued in subsequent years as new DNA reference samples were submitted; by 2020, approximately 241 of the 250 had been individually identified, a rate of approximately 96 percent, unprecedented for WWI remains.

The methodological lessons from Fromelles influenced subsequent WWI and WWII recovery projects globally. The embedded EOD model, the real-time public transparency protocol, and the simultaneous DNA reference collection that ran parallel to field excavation are now standard elements in large-scale conflict-casualty operations.

Identification Methods and Chain of Custody

The identification decision rests on the quality of everything that preceded it in the field.

Individual identification at a conflict site is a multi-source decision, not a single-test result. The identification board, which includes the forensic archaeologist, a forensic anthropologist, an odontologist, a DNA specialist, and (at military operations) a military historian, weighs all available evidence before issuing an identification. No single evidence stream is treated as conclusive without corroboration, except in exceptional circumstances where documentary evidence is unambiguous.

DNA kinship matching: the most powerful tool where living relatives exist. STR profiles provide identification strength equivalent to direct reference samples for first-degree relatives; SNP approaches extend this to more distant relatives.
Dental comparison: where service dental records survive, dental comparison can be definitive. For WWI, British Army dental records were not routinely kept, limiting this evidence stream; WWII and later conflicts have better dental record survival.
Identity discs and personal effects: presumptive identification, confirmed by one or more biological evidence streams where possible.
Skeletal biological profile: age-at-death, sex, and stature from the skeleton contribute to narrowing the candidate pool when combined with unit records and casualty lists.

The chain of custody begins with the body part number assigned at the grave during excavation. Every skeletal element, personal effect, and DNA sample collected from an individual carries a number traceable to its three-dimensional position within the site. This traceability is both a methodological requirement and, for international criminal tribunal work, a legal one. The integrity of the identification rests on the integrity of the spatial record.

Worked example

Identifying a WWI Casualty at Fromelles: From Pit to Named Headstone

How multiple evidence streams converge on a single identification for an individual recovered in 2009.

This is a composite account of the identification process as it applied to many of the 250 individuals recovered at Fromelles, drawing on the published Oxford Archaeology and Australian Army reports. It illustrates how the archaeological field record underpins every subsequent identification step.

Recovery and initial recording. An individual is exposed in Pit 3 during excavation. The skeleton is supine, oriented north-south, consistent with the pit arrangement. A metal-detector sweep of the exposed burial surface locates two metallic signals, one near the right side of the thorax and one near the left clavicle. Excavation reveals an identity disc (right thorax) and a cap badge (left clavicle). Both are photographed in situ with scale and north arrow before lifting. Total-station coordinates are recorded for the disc, the badge, and the cranium. A body bag number is assigned: FW09-PIT3-SK14.
Identity disc reading. The disc is cleaned in the field laboratory. It reads: a regimental number, a name, and an Australian unit designation. This provides a presumptive identification for one of several soldiers of that name listed as missing after Fromelles in the unit war diary.
DNA sampling. A molar tooth is selected for DNA extraction, packaged with the body bag number, and sent to the DSTL laboratory in the UK. The reference sample bank already holds a submission from a living grandnephew of the presumptively identified soldier, collected during the DNA outreach program.
DNA matching. The extracted STR profile from the molar shows a kinship index consistent with a grandnephew relationship to the reference sample. The statistical threshold for a positive identification is met.
Identification board. The board reviews: the identity disc (presumptive), the DNA kinship match (confirmatory), the biological profile from the skeleton (age-at-death 25-35 years, consistent with the soldier's known age of 29), and the unit context (the individual is buried in a pit whose composition is consistent with the unit's position in the battle). An individual identification is confirmed.
Reinterment. The identified individual is reinterred at Pheasant Wood CWGC Cemetery with a named headstone bearing his rank, name, unit, date of death, and the standard CWGC regimental badge. The body bag number in the site archive connects the grave to every piece of field evidence collected at FW09-PIT3-SK14.

The whole chain, from the identity disc found 30 centimetres below the surface of a French field to the named headstone, is held together by the spatial record made during those minutes of excavation in 2009. Remove the body bag number, lose the in-situ photograph, misrecord the coordinates, and the identification collapses.

Question 1 of 4· 0 answered

What are the two purposes of metal-detector survey before excavation at a conflict site?

Key Takeaways

Metal-detector survey before and during excavation serves two purposes: locating metallic personal effects that provide presumptive identification, and detecting unexploded ordnance requiring EOD clearance before safe excavation.
Projectiles and ordnance found in situ within burials are evidence of cause of death; their spatial position relative to the skeleton is recorded with total-station precision before lifting.
UXO safety protocols require immediate work stoppage, marking, withdrawal, and EOD contact; live ordnance is a routine discovery at WWI and WWII sites and must be treated accordingly.
The Fromelles 2008-2010 operation recovered 250 WWI soldiers from mass graves at Pheasant Wood and achieved approximately 96 percent individual identification by combining DNA kinship matching, identity discs, dental evidence, and skeletal biological profiles.
The chain of custody begins with the body bag number assigned at the point of in-situ recovery; every subsequent identification step is traceable through that number, making field-recording discipline the foundation of the entire identification outcome.

What is the Commonwealth War Graves Commission Joint Casualty and Compassionate Centre?

The CWGC JCCC is the UK Ministry of Defence unit responsible for recovering, identifying, and commemorating British military casualties. It commissions forensic archaeological excavations when conflict-era remains are discovered, coordinates with the CWGC for burial in marked graves, and manages the DNA and dental identification process in partnership with Defence Science and Technology Laboratory (DSTL).

Why is a metal-detector survey important before excavating a conflict site?

Metal-detector survey has two purposes: it locates metallic artefacts (identity discs, cap badges, personal effects, ammunition) that can provide presumptive identification before excavation, and it detects unexploded ordnance that must be cleared or avoided before safe excavation can proceed. Skipping the survey risks both evidence loss and serious injury to excavators.

What is the Fromelles operation and why was it significant?

The Battle of Fromelles on 19-20 July 1916 resulted in approximately 1,900 Australian and British soldiers buried by German forces in mass graves at Pheasant Wood, near Fromelles, France. The graves were located by historical research and LiDAR survey, confirmed by archaeological test excavation in 2008, and fully excavated in 2009-2010. Individual identification using DNA, dental records, and personal effects achieved a rate of approximately 96 percent, making it the largest identification operation for WWI remains to that date.

How are projectiles recorded in situ at a conflict excavation?

Projectiles, bullets, and shrapnel are recorded with a three-dimensional coordinate using a total station, photographed in situ with a scale bar and orientation indicator, described in terms of deformation and position relative to skeletal material, and only then lifted. Their position relative to bone can indicate the direction and angle of the wound track and contribute to cause-of-death determination.

What is the German War Graves Commission and how does it differ from the CWGC in its approach to battlefield recovery?

The Volksbund Deutsche Kriegsgraberfursorge (VDK) manages German military graves across more than 45 countries, recovering and reburying German casualties in collective or individual graves. Unlike the CWGC, which emphasises individual identification where possible, the VDK historically focused on collective commemoration. More recently, DNA-based identification programs have expanded German individual identification efforts, particularly in Eastern Europe.
