Album by Eric Dahlberg is a very interesting source for the study of the modern art of war. It has the form of book counting 150 cards; 140 of them are the battle, demonstration and instructional arrays, and 3 plans of the camps. In total, the album contains 288 essays, divided into six thematic chapters. The album is stored in the Military Archives (Krigsarkivet) in Stockholm. These sketches are largely unknown to the military historians. This applies above all to the Polish orders of battle. Knowledge on them could significantly deepen understanding of the traditional Polish art of war in the 17th c.; therefore, it seems appropriate to release Dahlberg album in print, which would disseminate knowledge on it among military historians.
