The author describes the battles and battlefields upon which this crisis was played out: from the first major action at Bov (9 April, 1848) to the last major battles of the war, at Isted (25 July 1850) and Missunde (12 September 1850), from the geomorphic landscape influencing battlefield strategy down to the description of a farmhouse where Prussian officers jumped out of windows to save themselves from the Danish. The reader is led through this war and shown the changing battlefields during this momentous period of European history.
