What event has a feature that has been described as "the first major military campaign fought entirely by air forces"?
Battle of Britain The Battle of Britain (German: "Luftschlacht um England" , literally "the air battle for England") was a military campaign of the Second World War, in which the Royal Air Force (RAF) defended the United Kingdom (UK) against large-scale attacks by the German Air Force (Luftwaffe). It has been described as the first major military campaign fought entirely by air forces.
Battle of Rabaul (1942) The Battle of Rabaul, also known by the Japanese as Operation R, was fought on the island of New Britain in the Australian Territory of New Guinea, in January and February 1942. It was a strategically significant defeat of Allied forces by Japan in the Pacific campaign of World War II, with the Japanese invasion force quickly overwhelming the small Australian garrison, the majority of which was either killed or captured. Hostilities on the neighbouring island of New Ireland are also usually considered to be part of the same battle. Rabaul was important because of its proximity to the Japanese territory of the Caroline Islands, site of a major Imperial Japanese Navy base on Truk.
