The ancient forests of Poland in the Napoleonic documents held in the French military archives in Vincennes

Military archives of the French Army at Vincennes retain many documents of the Napoleonic war. Some of these documents relate to Poland and Lithuania. The military intelligence reports have sometimes been subject to the forests. The article presents the analysis of three of these documents. The two reports on the forests of Lithuania and a forestry part of a report of General Sokolnicki. These documents hitherto unknown, are an interesting testimony on the forests in Poland and the French know about them in the early nineteenth century. It is also an interesting contribution to understanding the role of forests in the military policy of the time.
