The Anglo-Russian invasion of Holland (or Anglo-Russian expedition to Holland, or Helder Expedition) refers to the campaign of 27 August to 19 November 1799 during the War of the Second Coalition, in which an expeditionary force of British and Russian troops invaded the North Holland peninsula in the Batavian Republic. The campaign had two strategic objectives: to neutralize the Batavian fleet and to promote an uprising by followers of the former stadtholder William V against the Batavian government. The invasion was opposed by a combined Franco-Batavian army of approximately equal strength. Tactically, the Anglo-Russian forces were successful initially, defeating the defenders in the battles of Callantsoog and the Krabbendam, but subsequent battles went against the Anglo-Russian forces.
