Danish Warship Sunk by Admiral Nelson Discovered After 225 Years
Marine archaeologists have made a historic discovery, locating the wreck of a Danish warship that sank during the 1801 Battle of Copenhagen, exactly 225 years after it was sunk by the famed British admiral Horatio Nelson and his fleet. The find was announced by Denmark’s Viking Ship Museum, which is leading the underwater excavations in Copenhagen Harbour.
Race Against Time in Murky Waters
Divers are working urgently in challenging conditions, at a depth of 15 meters (49 feet) with thick sediment and near-zero visibility, to uncover the 19th-century wreck of the Danish flagship Dannebroge. This effort is critical because the site is set to become part of a construction zone for Lynetteholm, a major housing district project in Copenhagen Harbour scheduled for completion by 2070.
Morten Johansen, head of maritime archaeology at the Viking Ship Museum, emphasised the national significance: “It’s a big part of the Danish national feeling. A great deal has been written about the battle by very enthusiastic spectators, but we actually don’t know how it was to be onboard a ship being shot to pieces by English warships. Some of that story we can probably learn from seeing the wreck.”
The Brutal Battle of Copenhagen
In the Battle of Copenhagen, Nelson and the British fleet attacked and defeated Denmark’s navy, which was forming a protective blockade outside the harbour. Thousands were killed or wounded in the hours-long naval clash, considered one of Nelson’s great battles. The British aim was to force Denmark out of an alliance with Northern European powers, including Russia, Prussia, and Sweden.
At the heart of the fighting was the 48-meter (157-foot) Danish flagship Dannebroge, commanded by Commodore Olfert Fischer. It was Nelson’s primary target; cannon fire tore through its upper deck, and incendiary shells sparked a fire aboard. Johansen described the horror: “(It was) a nightmare to be on board one of these ships. When a cannonball hits a ship, it’s not the cannonball that does the most damage to the crew, it’s wooden splinters flying everywhere, very much like grenade debris.”
Historical Artifacts and Personal Stories
Archaeologists have recovered numerous artifacts from the wreck, including two cannons, uniforms, insignia, shoes, bottles, and even part of a sailor’s lower jaw—possibly from one of the 19 crew members unaccounted for after the battle. The darkened dig site is littered with cannonballs, posing hazards for divers navigating waters clouded by silt.
Diver and maritime archaeologist Marie Jonsson shared the difficulties: “Sometimes you can’t see anything, and then you really have to just feel your way, look with your fingers instead of with your eyes.” She noted the personal touches found: “There are bottles, there are ceramics, and even pieces of basketry. You get closer to the people onboard.”
Verification and Legacy
Experts have confirmed the wreck’s identity through methods like dendrochronological dating, which uses tree rings to establish the wood’s age, matching the year the ship was built. The sizes of wooden parts also align with historical drawings. The battle, chronicled in books and paintings, is deeply embedded in Denmark’s national story, and this discovery offers a chance to reexamine the event and uncover personal narratives from that day.
Interestingly, the battle is believed to have inspired the phrase “to turn a blind eye.” Nelson, who had lost sight in his right eye, reportedly said after ignoring a superior’s signal: “I have only one eye, I have a right to be blind sometimes.” After the Dannebroge drifted northward and exploded—creating a deafening roar across Copenhagen—Nelson eventually offered a truce, leading to a ceasefire with Denmark’s Crown Prince Frederik.
This discovery not only sheds light on a pivotal historical moment but also connects modern Danes to their past, as archaeologists continue to piece together the final hours of the Dannebroge and its crew.
