In 1799 an uneasy Anglo-Russian alliance, formed as part of the Second Coalition against France, landed troops in Holland to overthrow the Batavian Republic, a French satellite, and reinstate Willem V of Orange. Van Uythoven gives a comprehensive account of this ‘Secret Expedition’ and its background, from the creation of the Batavian Republic, through the invasion and the battles of Zijpe, Bergen, Alkmaar and Castricum, to the Armistice and the state of the armies at the end of the campaign.
