The Battle of Callantsoog (sometimes also called Battle of Groote Keeten) (27 August 1799) followed the amphibious landing by a British invasion force under Lieutenant-General Sir Ralph Abercromby near Callantsoog in the course of the Anglo-Russian Invasion of Holland of 1799. Despite strong opposition by troops of the Batavian Republic under Lieutenant-General Herman Willem Daendels the British troops established a bridgehead and the Dutch were forced to retreat.
