Archeologia Bitwy Warszawskiej 1920 roku – zagadnienia wprowadzające

The article is a preliminary presentation of the project “Inventory of selected relics of the Battle of Warsaw 1920”, commissioned by the Masovian Monuments Preservation Officer and carried out in 2020 – the centenary of the battle, known also as the “Miracle on the Vistula”. The research was carried out by the Hereditas Foundation in cooperation with the Forest Research Institute and the Historical and Educational Association of 7th Regiment of Vistula Lancers in Halinów. This initiative was an interdisciplinary undertaking based, among others, on the cooperation of a team of specialists in the fields of archaeology, history, geography, remote sensing and geoinformatics, as well as forestry. The main discussion in the article focuses on introductory issues concerning the archaeology of the Battle of Warsaw - archaeological research, concentrating mainly on non-intrusive and inventory activities. At the same time, the article contributes to the discussion about, among others, the definition, recognition and protection of battlefield relics – the so-called large-scale archaeological sites. The publication presents selected research results (numerous identified relics of armed conflicts – mainly field fortifications – from the area of the Warsaw Bridgehead, primarily from World War I and II, as well as from the Polish-Bolshevik war). The text also discusses basic elements of the research methodology, based (mainly) on GIS tools and data sourced from the Information System of National Protection Against Extraordinary Risks (ISOK) – obtained during airborne laser scanning. The key element of the project, and at the same time one of the results of the research, is a data set (prepared for heritage services or specific land managers) in the form of a spatial information system known as “H/A-GIS Bitwa Warszawska 1920”.
