1864 – Political folly has brought war upon Denmark. Lacking allies, the country is invaded by the forces of military superpowers Prussia and Austria. Cut off from the main Danish Army, and refusing to use the word ‘retreat’, a resolute commander withdraws northwards. Harried by Austrian cavalry, his forces plod through snow, sleet and mud, their determination not to be defeated increasing with each weary step . . .
Across the Atlantic, civil war rages. It is fought not solely on American soil but also on the world’s oceans, as Confederate commerce raiders ravage Union merchant shipping as far away as the East Indies. And now a new raider, a powerful modern ironclad, is nearing completion in a British shipyard. But funds are lacking to pay for her armament and the Union government is pressing Britain to prevent her sailing . . .
Denmark is not wholly without sympathizers however. Britain’s heir to the throne is married to a Danish princess. With his covert backing, British volunteers are ready to fight for the Danes. And the Confederacy is willing to lease the new raider for two months if she can be armed and supplied as payment , although the Union government is determined to see her sunk . . .
