(April 2, 1801) British naval victory over Denmark in the Napoleonic Wars .
The armed-neutrality treaty of 1794 between Denmark and Sweden, to which Russia and Prussia adhered in 1800, was considered a hostile act by England. In 1801 a detachment of the British navy was sent to Copenhagen. After a fierce battle in the harbor, Adm. Horatio Nelson , ignoring orders to withdraw from the fleet commander, Sir Hyde Parker, instead continued to destroy most of the Danish fleet. Danish losses amounted to some 6,000 dead and wounded, six times those of the British. Denmark subsequently withdrew from the neutrality treaty.
