The thrilling narrative by J.F. Schröder is set against the backdrop of the historical events of the year 1626. The great war, later known as the Thirty Years' War, rages on. The troops of General Tilly and his adversaries devastate the land between the Weser and the Harz mountains. The situation for Field Marshal Tilly and his soldiers becomes increasingly difficult - the plundered land offers little in terms of resources. Supply from the south is almost completely cut off, as the opponents have their hands in the game. The author describes the adventurous mission of Captain Mathias Graf von Falkenberg and his servant Hans Meinrad, the outcome of which determines the fate of thousands of people.
