Defining the Inventory boundary
The Inventory boundary defines an area which is considered to encompass the landscape within which the main events of the battle took place (landscape context) and where associated physical remains and archaeological evidence occur or may be expected (specific qualities).
The landscape context includes areas of fighting, key movements of troops across the landscape and other important locations, such the position of camps or vantage points. Although the landscape will have changed to some degree since the time of the battle, it may nevertheless still retain key characteristics of the terrain that are important to enable events, and their landscape context, to be fully understood and interpreted. Specific qualities include landscape features that played a significant role in the battle, other physical remains, such as enclosures or built structures, and areas of known or potential archaeological evidence.
The boundary has been defined on the basis of research of documentary sources and historic terrain maps, and through landscape analysis to locate events in the modern landscape. Additional sources of information, such as place-names and military find-spots, can also be helpful.
Overall the area defined is considered to have high potential to retain important landscape characteristics, specific features, strategic viewpoints and archaeological deposits associated with the battle, all of which are key to understanding the course of the events of the battle.
It is possible that additional evidence relating to the events of the battle, such as extended lines of approach, retreat or rout, will survive beyond the defined boundary, though this is likely to be more dispersed in nature.
