When Denmark-Norway Tried to Bomb Algiers into Submission and Failed Miserably
In 1769, a diplomatic dispute over tribute payments ignited a three-year conflict between Denmark-Norway and the Regency of Algiers. What began as a bold punitive expedition to secure trade routes quickly devolved into a humiliating military failure, leaving the Danish-Norwegian fleet battered, disease-ridden, and forced to pay for peace.
The conflict was rooted in the expansion of Danish-Norwegian Mediterranean trade during the mid-1700s. To shield their commercial interests from piracy, the Dano-Norwegian state paid annual tributes to the rulers of the Barbary Coast. Tensions spiked in 1766 when Baba Mohammed ben-Osman, the newly appointed Dey of Algiers, demanded higher payments and additional gifts. When Denmark-Norway rejected these terms, Algerian pirates seized three merchant ships and enslaved their crews, prompting a military response.
On May 16, 1770, a squadron led by Frederik Christian Kaas departed Copenhagen, consisting of four ships of the line, two frigates, and two bomb galiots. Their objective was to force a favorable peace through the bombardment of Algiers. The mission failed spectacularly. The fleet faced heavy mortar fire that damaged their hulls, while a devastating typhoid outbreak incapacitated a large portion of the crew. After firing roughly 75 bombs at the city, the expedition was forced to abandon the assault and shift to a blockade.
The war concluded in 1772 after a delegation negotiated a new peace agreement. The terms were far from a victory for the Danish-Norwegian side; they were required to pay Algiers a significant sum to secure peace. Furthermore, the state had to pay for the return of captured slaves, while those sold to private owners were left to negotiate their own freedom prices individually. Today, the conflict remains largely forgotten, viewed as a minor footnote in Scandinavian history, though it was later dramatized in the 2013 novel 1001 natt by Vetle Lid Larssen.
