British bombardment of Copenhagen

British bombardment of Copenhagen. The British bombardment of Copenhagen was a preemptive military assault launched by the United Kingdom against the neutral capital of Denmark–Norway from 2 to 5 September 1807. The operation, a major episode of the Napoleonic Wars, aimed to seize the powerful Danish fleet to prevent its potential use by Napoleonic France. The intense shelling resulted in significant civilian casualties and the capture of the Danish navy, profoundly altering Denmark's role in the European conflict and its relationship with Britain.

Background and causes

The primary catalyst was the Treaty of Tilsit, signed in July 1807 between Emperor Napoleon of France and Tsar Alexander I of Russia. This secret pact threatened to force the neutral Denmark–Norway into the Continental System, a French-led economic blockade against Britain. British intelligence, including reports from diplomat Francis James Jackson, indicated that Napoleon might compel Denmark to surrender its formidable fleet. Fearing this would decisively shift naval power in the Baltic Sea, the British government under Prime Minister Portland and Foreign Secretary George Canning authorized a preemptive strike. The decision was controversial but driven by the strategic imperatives of the Napoleonic Wars, following the precedent of the earlier Battle of Copenhagen.

The British expedition

A massive expeditionary force was assembled with remarkable speed and secrecy. Command of the naval squadron was given to Admiral James Gambier, while the army corps was led by General Arthur Wellesley, later the victor of the Battle of Waterloo. The fleet, comprising over 25 ships of the line and hundreds of transports, carried around 30,000 troops. It sailed from Yarmouth in late July and arrived in the Øresund by mid-August. After landing at Vedbæk north of Copenhagen, Wellesley's forces, which included units from the King's German Legion, swiftly surrounded the city. An ultimatum was delivered to the Danish commander, General Ernst Peymann, and the regent, Crown Prince Frederick, demanding the temporary surrender of the fleet. Upon the Danish refusal, the British began siege operations.

The bombardment

The bombardment commenced on the evening of 2 September 1807. British land-based artillery and specially adapted bomb vessels, including HMS Thunder and HMS Vesuvius, began a relentless shelling of the city using Congreve rockets and incendiary carcasses. The attack focused on the civilian centre and the naval dockyards, with the Church of Our Lady and the University of Copenhagen library suffering severe damage. Despite a brave but outgunned defence from the city's fortifications and militia, the Danish forces could not halt the destruction. After three nights of intense fire, which caused catastrophic urban fires, General Peymann capitulated on 5 September to prevent further civilian slaughter.

Aftermath and consequences

The capitulation terms were severe. The British captured the entire Danish fleet, comprising 18 ships of the line, 15 frigates, and numerous smaller vessels. These were swiftly taken to British ports, notably Portsmouth. The bombardment shattered Danish neutrality, pushing Denmark into a full alliance with France and initiating the Gunboat War, a naval conflict with Britain that lasted until 1814. The city of Copenhagen suffered immensely, with an estimated 1,600 civilian deaths and nearly a third of its buildings destroyed. The event caused international outrage, with critics like Richard Brinsley Sheridan condemning it in the House of Commons, while the government defended it as a grim strategic necessity.

Legacy and historical assessment

Historically, the bombardment is viewed as a ruthless but strategically successful action that secured British naval supremacy in the Baltic Sea during a critical phase of the Napoleonic Wars. It demonstrated the United Kingdom's willingness to use overwhelming force against a neutral state for perceived national survival, a precedent often compared to the 1940 attack on the French fleet at Mers-el-Kébir. In Denmark, the event is remembered as a national trauma, a "second disaster" after 1801, which fueled anti-British sentiment and contributed to the nation's bankruptcy and the loss of Norway in 1814. The operation also cemented the rising reputations of commanders like Arthur Wellesley, whose efficient campaign foreshadowed his later triumphs in the Peninsular War.
