List of World War II battles

This is a list of World War II battles encompassing land, naval, and air engagements as well as campaigns, military operations, and sieges. Campaigns generally refer to broader strategic operations conducted over a large area of territory and over a long period. Battles generally refer to short periods of intense combat localised to a specific area and over a specific period. However, use of the terms in naming such events is not consistent. For example, the Battle of the Atlantic was more or less an entire theatre of war, and the so-called battle lasted for the duration of the entire war.
