The campaigns of World War II were the military operations that were employed during World War II. Campaigns generally refer to broader strategic operations conducted over a large bit of territory and over a long period of time. Battles generally refer to short periods of intense combat localized to a specific area and over a specific period of time. 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 theater of war, and the so-called battle lasted for the duration of the entire war. Another misnomer is the Battle of Britain, which by all rights should be considered a campaign, not a mere battle.
