Battle of Silda (Affæren ved Silden or Affæren ved Stadt) was a naval battle fought on 23 July 1810 between the United Kingdom of Great Britain and Ireland and Denmark–Norway near the Norwegian island of Silda in Sogn og Fjordane county.

The Dano-Norwegian Navy had based three gun-schooners Odin, Thor, and Balder, and the gun-barge Cort Adeler at the pilot station on Silda.

[Note 1] The British took the other two captured vessels as prizes and sent their crews as prisoner of war in England.

On the evening of 22 July a boat from Belvidera scouting a deep bay sighted three Dano-Norwegian gun-vessels.

[3] The local Norwegian commander, vicar Gabriel Heiberg, failed to alert other Dano-Norwegian naval vessels nearby that could have helped repel the attack.
