The Napoleonic Wars

In 1801, during the Napoleonic Wars, the first optical telegraphs were introduced into Denmark. Threatened by attacks from the British Navy, the Danish Admiralty became convinced of the sense of the Signalling Commission´s proposal to establish a line of Fisker-type telegraphs along the coast of the Sound. It was political strategies, therefore, that resulted in Fisker´s telegraph, rather than Walterstorff´s, becoming widely used in Denmark.
