Over the last two decades conflict archaeology has developed from Historic archaeology to include multiple elements in the fields of anthropology and archaeology. Early efforts include 1842 surveys of the English Civil War site of Naseby, and in the twentieth century the 1950s examination of the Portuguese battle of Aljbarotta of AD1325.[7] In the United States attention was drawn to the possibilities of conflict archaeology in the National Parks sites of Little Big Horn and selected Civil Battle fields.[8] Much of the work done on these later sites was with metal detectors.[9] Although this technology has received a less than warm welcome to field work due to its use in relic hunting, it has become a staple in many investigations. Relic hunting was around long before the metal detector was invented.
Since much of conflict archaeology has been from the historic period, documentary research remains a primary starting point for the process. Published documents, maps, chart, aerial photography all aid in getting preliminary starting point. Field work will then include pedestrian survey and possibly remote sensing, including not only metal detecting, but also magnetometry, Ground Penetrating Radar(GPR), Resistivity, and more recently, Light Detection and Ranging (LIDAR). This ability to sense what is beneath the surface often allows for the true location of structure. In conflict archaeology these are often fortifications such as trenches, breastworks as well as housing, transportation and storage areas.
Facilities away from the battlefield itself are also a concern of conflict archaeology. Other complexes such as supply, food preparation, sanitation, transportation, command structures, facilities for prisoners, hospitals and possibly the burial of the dead.[10][11][12]
Structural elements and fortifications may be mobile or static, short term or long term, and may even have multiple occupations during protracted periods. Identification of these structures should reflect the cultural tendencies of a group in that period. Following that theme, the location through remote sensing and traditional test excavation may reveal elements of conflict at a more personal level. All of this may be used to observe first hand behavior of groups and individuals under the stress of battle.
Cultural patterns-One of the approaches to working in this area is to understand the nature of conflict of given cultures. Not all people fight the same way. By studying the cultural signature of opposing groups, insight may be gained to help interpret not only the battlefield, but also the areas involved in pre and post conflict activities.
Training is one of these areas. Again, not all people fight the same way given their individual histories, demographic makeup, as well as technical and natural resources. Also, people tend to fight the way they were trained, so that in examining an area of conflict similar patterns are likely to appear. The way the forces reconnoiter, approach, deploy and exit a conflict will often reflect a given group's training, hence these may be predicted, thereby locating archaeological evidence by studying the groups training or cultural proclivities.
Terrain in the purely geographical sense has long been an element of archaeological investigations and reports, but terrain has a critical role that is part of not only battle field conflict but staging areas, routes for access and withdrawal, and movement before, during and after the conflict itself. An area for conflict and pre and post activities will yield significantly different kinds of materials for observation. Theaters of conflict between a colonial power and an indigenous group will most probably yield significantly different archaeological records. How the area was chosen, and to what purpose can reveal strategies and tactics such as siege or holding operations. Clandestine and guerrilla tactics will often manifest themselves in different kinds of bases and transport operations such as tunnels and caves.
Time and space are also pivotal considerations for the study of conflict. Time may be measured in seconds or years even decades or longer. Opportunities for the deposition of archaeological evidence may consist of very minuscule traces to layers of multiple accumulations, all telling unique stories. The same applies to space. It too may range from a single event of ‘one on one’ contact to fields of conflict that are truly global in nature. The events that are small in physical scale, again may or may not leave much evidence, but the larger episodes my in fact completely alter the landscape. Large construction projects of camps, docks, airfields as well as fortifications may remain for centuries.[13]
Alterity is the concept of identifying those groups who have been omitted in traditional historical narratives, sometimes identified as 'others;. Conflict archaeology seeks to be more inclusive regarding non-traditional narratives that focus less on purely military aspects of battle. The roles of indigenous peoples, insurgents, and noncombatants have been greatly under reported in both the historic and archaeological reports on conflict. Adding to these should be women and children who are often integral elements in conflict scenarios as the adult male participants.[14] These are often the under-reported participants of support, espionage, and partisan activities.
A close inspection of the documents of a period of colonialism will often reveal that the recordings of conflict will reflect the justifications of the subjecting power. These ‘histories’ may be nothing more than period propaganda and will often be perpetuated into long studied and repeated narratives. These will also ignore, or downplay, or intentionally omit the role of the subaltern players in those dramas.[15] Examples of some of the new examinations range from the Fascist control over Ethiopia during the 1930s to massacres of Aboriginals in Australia.[16]
Recent innovations in the study and identification of human remains have been utilized in the last three decades is drawing the study of conflict and archaeology into prominence.[17] Modern examples of extra-national conflicts, civil wars, episodes of genocide, concentration camps, ‘ethnic cleansing’ are producing execution sites, mass graves and other archaeological evidences. These episodes are heavily involving conflict archaeology into the legal theatre to augment evidence of war crimes and atrocities. The same recovery techniques are also being used to repatriate remains to families and provide closure to events that may span decades.[18][19]
