Marine Archaeologists Uncover 19th-Century Warship Wreck in Copenhagen Harbor

Marine archaeologists from Denmark's Viking Ship Museum have discovered the wreck of the Dannebroge, a 60-gun warship sunk in 1801 during the Battle of Copenhagen. The ship was destroyed by British forces led by Admiral Horatio Nelson in an effort to dismantle the League of Armed Neutrality, an alliance that threatened British trade interests. The excavation, led by Otto Uldum, began in late 2025 at a site in Copenhagen Harbor known as King's Deep, with initial findings released on April 2, 2026, marking 225 years since the battle. Artifacts recovered include two cannons, uniform fragments, bottles, shoes, and human remains, with the ship's identity confirmed through dendrochronological dating linking its wood to 1772 and matching its dimensions to historical drawings. The discovery is significant as the first archaeological investigation directly tied to the Battle of Copenhagen, providing new insights into a pivotal event in Danish history. The wreck is at risk due to planned housing development on an artificial island, prompting urgent salvage efforts. Divers face challenges from poor visibility at depths of 50 feet, relying on touch for navigation. In a historical irony, the battle's objective became moot when the League collapsed days earlier due to the assassination of Russia's Tsar Paul I.
