"The summer of 1872 saw the World War reach new heights of chaos as the Ottoman Empire pledged themselves to the Imperial Bond and the Grand Republique of France launched its forces south across the Mediterranean. All eyes turned to the new front, North Africa... or at least, almost all.
In the Atlantic, Prussian raiding had caused untold damage to the convoys crossing between Europe and the Americas. Operating out of bases at Greenland, Iceland and the new Bermudan territories, their reach was long and repercussions had been all but non-existent as the Britannian and American fleets struggled to allocate resources away from protecting the convoys, the major operations in the Pacific, and around mainland Europe.
Nonetheless, early June 1872 saw the Federated States of America appoint the veteran Rear-Admiral Curt J. Spaatz a small expedition of ships to test the defences of one of the major Prussian harbours on Greenland, Holsteinsborg - the northernmost ice-free port in the country. His mission, to break off from convoy duty and engage the Prussian fleet at Holsteinsborg as they sat in anchor, aiming to cripple the core fleet of the infamous reaver Karl-Ehrhart Grunner.
Grunner, however, was fully aware of Spaatz' approach..."
