Centuries-Old Danish Warship Discovered in Copenhagen Harbor
More than two centuries after being sunk by Admiral Horatio Nelson and the British fleet, a significant Danish warship has been located on the seabed of Copenhagen Harbor by dedicated marine archaeologists. This remarkable discovery comes 225 years to the day since the historic Battle of Copenhagen in 1801, a pivotal naval engagement that shaped Denmark's national identity.
A Race Against Time and Construction
Working in challenging conditions with thick sediment and near-zero visibility at a depth of 15 meters (49 feet), divers are now in a critical race against time to excavate the 19th-century wreck of the Dannebroge. The urgency stems from impending construction work for Lynetteholm, a massive housing district project in the middle of Copenhagen Harbor scheduled for completion by 2070. The underwater excavations, led by Denmark's Viking Ship Museum, were announced on Thursday, marking the exact anniversary of the battle.
"It's a big part of the Danish national feeling," emphasized Morten Johansen, the museum's head of maritime archaeology. He noted that while much has been written about the battle by enthusiastic spectators, "we actually don't know how it was to be onboard a ship being shot to pieces by English warships and some of that story we can probably learn from seeing the wreck." The Associated Press was granted exclusive international access to the sensitive archaeological site.
The Historic Battle of Copenhagen
In the Battle of Copenhagen, Admiral Horatio Nelson and the British fleet launched a devastating attack on Denmark's navy, which had formed a protective blockade outside the harbor. The brutal hours-long naval clash resulted in thousands of casualties and is regarded as one of Nelson's "great battles." The British objective 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 Danish flagship, the 48-meter (157-foot) Dannebroge, commanded by Commodore Olfert Fischer. This vessel was Nelson's primary target. During the engagement, cannon fire ripped through its upper deck, and incendiary shells ignited a catastrophic fire aboard.
"(It was) a nightmare to be on board one of these ships," Johansen described. "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."
Archaeological Treasures and Historical Insights
Marine archaeologists have already uncovered a wealth of artifacts from the wreck site, including two cannons, uniforms, insignia, shoes, bottles, and even part of a sailor's lower jaw. This latter discovery may belong to one of the 19 crew members who remain unaccounted for and likely perished during the battle. The stricken Dannebroge eventually drifted northward before exploding, with historical records noting that the blast produced a deafening roar heard across Copenhagen.
Experts have confirmed the identity of the wreck through meticulous analysis. The sizes of recovered wooden parts correspond with old drawings, and dendrochronological dating—using tree rings to determine the age of wood—aligns with the year the ship was constructed. The dig site is also littered with cannonballs, posing a significant hazard for divers navigating waters clouded by silt stirred from the seabed.
"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," explained diver and maritime archaeologist Marie Jonsson.
Reexamining a National Story
The 1801 battle, chronicled in numerous books and depicted in paintings, is deeply embedded in Denmark's national narrative. Interestingly, this conflict is believed to have inspired the phrase "to turn a blind eye." After choosing to ignore a signal from a superior, Nelson, who had lost sight in his right eye, reportedly remarked: "I have only one eye, I have a right to be blind sometimes." Nelson later offered a truce, leading to a ceasefire agreement with Denmark's Crown Prince Frederik.
Archaeologists are hopeful that their discoveries will provide new perspectives on the event that profoundly influenced the Scandinavian country. By uncovering personal items and human remains, they aim to reveal the individual stories of those who fought on that fateful day 225 years ago.
"There are bottles, there are ceramics, and even pieces of basketry," Jonsson noted. "You get closer to the people onboard." This intimate connection to history underscores the importance of preserving and studying the Dannebroge before it is lost forever to modern development.
