HDMS Danmark: Key Ships Series 1, Ship 2

HDMS Danmark began as a Confederate order for an ocean-going ironclad intended to challenge the Union blockade.

France restricted Confederate ship construction because such sales might push Britain into active support for the Union blockade and make Confederate defeat more likely.

British political limits and the ship's demands on Confederate manpower and draught left the unfinished ironclad available for Denmark in 1864.

The Second Schleswig War placed Denmark alone against Prussia and Austria after renewed conflict over the duchies of Schleswig and Holstein.

Schleswig's mixed linguistic landscape and the political preferences of its clergy and nobility complicate a simple Danish-versus-German account of the duchies.

Danish tolls on Baltic trade and the prospect of a canal around them made control of Holstein important to Prussian and Austrian strategy.

The succession struggle between the Glücksburg and Augustenburg branches tied Denmark's crown to the dispute over Schleswig-Holstein and Germany.

Danmark's changing gun battery reflected the value of rate of fire, but heavy rolling and high coal consumption made her an expensive disappointment.

Danmark's failures frame a larger counterfactual question: what kind of ocean-going ironclad would the Confederacy have needed to challenge the Union blockade?

The closing proposal considers whether a militia-based Home Guard could have delayed a much larger Prussian-Austrian invasion by obstructing roads and crossings.
