Admiral Lord Gambier sent the 74-gun third rate and the 22-gun sixth rate after her, even though war had not yet been declared. "Comus" was much faster than "Defence" in the light winds and so outdistanced her. On 15 August, "Comus" caught "Friderichsværn" off Marstrand and captured her. The British took her into service as HMS "Frederikscoarn". The British troops under General Lord Cathcart were organised as follows:  The Danish forces in the city amounted to 5,000 regular troops and a similar number of militias. Most of the civilian inhabitants of Copenhagen were evacuated in the few days before Copenhagen was completely invested. On 26 August, General Wellesley was detached with his reserve and two light brigades of British artillery, as well as one battalion, eight squadrons and one troop of horse artillery from the King's German Legion (KGL) to disperse a force which had been sent to relieve the beleaguered city. On 29 August, at the rivulet of Køge, this significant British force swiftly overpowered the Danish troops, which amounted to only three or four regular battalions and some cavalry (see Battle of Køge). The Danes rejected British demands, so the British fleet under Admiral Gambier bombarded the city from 2 to 5 September 1807. In addition to the military casualties, the British bombardment of Copenhagen killed some 195 civilians and injured 768. The bombardment included 300 Congreve Rockets, which caused fires. Due to the civilian evacuation, the normal firefighting arrangements were ineffective; over a thousand buildings were burned. On 5 September, the Danes sued for peace, and the capitulation was signed on 7 September. Denmark agreed to surrender its navy and its naval stores. In return, the British undertook to leave Copenhagen within six weeks. Peymann had been under orders from the Crown Prince to burn the Danish fleet, which he failed to do, though the reason for his failure is unknown. Thus, on 7 September 1807 Peymann surrendered the fleet (eighteen ships of the line, eleven frigates, two smaller ships, two ship-sloops, seven brig-sloops, two brigs, one schooner and twenty-six gunboats). In addition, the British broke up or destroyed three 74-gun ships-of-the-line on the stocks, along with two of the ships-of-the-fleet and two elderly frigates.
