Amphibious operations were not technologically impossible before the Second World War. Gallipoli, the Russo-Swedish War, and other earlier campaigns supplied an established body of experience. Britain also possessed amphibious doctrine even when it failed to employ that doctrine effectively. The historical examples separate what was possible in principle from the preparation and coordination needed to make a particular landing work.

Historical examples and British doctrine show that amphibious operations were possible before the Second World War, although difficult execution could still ruin them.
