The Battle of Lyngør was fought on 6 July 1812 between the British and Dano-Norwegian navies as part of the Gunboat War. A British squadron of one ship of the line and three brig-sloops under James Stewart located the Dano-Norwegian frigate Najaden sheltering off Lyngør, and engaged and destroyed her in a fierce engagement; Najaden's captain Hans Peter Holm was wounded but survived, but 133 of his crew were killed and a further 87 wounded. The British in contrast suffered only 9 killed and 26 wounded, and the battle led to the destruction of Denmark–Norway's last major warship.
