Copenhagen (Napoleonic Wars).

The city was captured September 5, 1807, by 20,000 British troops under Lord Cathcart, after a four days' bombardment of the forts and citadel by 27 ships of the line. The Danish fleet of 18 sail of the line, which was surrendered, would otherwise, under a secret clause of the Treaty of Tilsit, have been placed at the disposal of Napoleon.
