This is a list of World War II battles encompassing land, naval, and air engagements as well as campaigns, operations, defensive lines and sieges. Campaigns generally refer to broader strategic operations conducted over a large bit 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. Another misnomer is the Battle of Britain, which by all rights should be considered a campaign, not a mere battle.

Small to medium-sized raiding operations were carried out by both Allied and Axis armies during World War II. The modus operandi used included guerrilla attacks by partisans in occupied territory and/or combined operations involving the landing and removal of specialised light infantry, such as commandos, by means of small boats.
Raiding units
The European Theater of Operations, United States Army (ETOUSA) was a theater of Operations responsible for directing United States Army operations throughout the European theatre of World War II, from 1942 to 1945. It commanded Army Ground Forces (AGF), United States Army Air Forces (USAAF), and Army Service Forces (ASF) operations north of Italy and the Mediterranean coast. It was bordered to the south by the North African Theater of Operations, United States Army (NATOUSA), which later became the Mediterranean Theater of Operations, United States Army (MTOUSA).
The Asiatic-Pacific Theater was the theater of operations of U.S. forces during World War II in the Pacific War during 1941–1945. From mid-1942 until the end of the war in 1945, two U.S. operational commands were in the Pacific. The Pacific Ocean Areas (POA), divided into the Central Pacific Area, the North Pacific Area and the South Pacific Area, were commanded by Fleet Admiral Chester W. Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area (SWPA) was commanded by General of the Army Douglas MacArthur, Supreme Allied Commander South West Pacific Area. During 1945, the United States added the United States Strategic Air Forces in the Pacific, commanded by General Carl A. Spaatz.
During World War II, the United States Army divided its operations around the world into four theaters. Forces from many different Allied nations fought in these theaters. Other Allied countries have different conceptions of the theaters and/or different names for them.
The Pacific War, sometimes called the Asia–Pacific War or the Pacific Theater, was the theater of World War II that was fought in eastern Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War in the last few months of the war.
The Asiatic–Pacific Campaign Medal was a United States military award of the Second World War, which was awarded to any member of the United States Armed Forces who served in the Asiatic-Pacific Theater from 1941 to 1945. The medal was created on November 6, 1942, by Executive Order 9265 issued by President Franklin D. Roosevelt. The medal was designed by Thomas Hudson Jones; the reverse side was designed by Adolph Alexander Weinman which is the same design as used on the reverse of the American Campaign Medal and European-African-Middle Eastern Campaign Medal.
The South-East Asian Theatre of World War II consisted of the campaigns of the Pacific War in the Philippines, Thailand, Indonesia, Indochina, Burma, India, Malaya and Singapore between 1941 and 1945.
Berlin, the capital of Nazi Germany, was subject to 363 air raids during the Second World War. It was bombed by the RAF Bomber Command between 1940 and 1945, the United States Army Air Forces' Eighth Air Force between 1943 and 1945, and the French Air Force in 1940 and between 1944 and 1945 as part of the Allied campaign of strategic bombing of Germany. It was also attacked by aircraft of the Red Air Force in 1941 and particularly in 1945, as Soviet forces closed on the city. British bombers dropped 45,517 tons of bombs, while American aircraft dropped 22,090.3 tons. As the bombings continued, more and more people fled the city. By May 1945, 1.7 million people had fled.
Battle Honours are awarded by the Sovereign to Royal Air Force squadrons to commemorate the squadron's role in a particular operation.
The New Guinea campaign of the Pacific War lasted from January 1942 until the end of the war in August 1945. During the initial phase in early 1942, the Empire of Japan invaded the Territory of New Guinea on 23 January and Territory of Papua on 21 July and overran western New Guinea beginning on 29 March. During the second phase, lasting from late 1942 until the Japanese surrender, the Allies—consisting primarily of Australian forces—cleared the Japanese first from Papua, then New Guinea, and finally from the Dutch colony.
The military history of the United States during World War II covers the nation's role as one of the major Allies in their victory over the Axis Powers. The United States is generally considered to have entered the conflict with the 7 December 1941 surprise attack on Pearl Harbor by the Empire of Japan and exited it with the 2 September 1945 surrender of Japan. During the first two years of World War II, the US maintained formal neutrality, which was officially announced in the Quarantine Speech delivered by US President Franklin D. Roosevelt in 1937. While officially neutral, the US supplied Britain, the Soviet Union, and China with war materiel through the Lend-Lease Act signed into law on 11 March 1941, and deployed the US military to replace the British forces stationed in Iceland. Following the 4 September 1941 Greer incident involving a German submarine, Roosevelt publicly confirmed a "shoot on sight" order on 11 September, effectively declaring naval war on Germany and Italy in the Battle of the Atlantic. In the Pacific Theater, there was unofficial early US combat activity such as the Flying Tigers.
The South West Pacific theatre, during World War II, was a major theatre of the war between the Allies and the Axis. It included the Philippines, the Dutch East Indies, Borneo, Australia and its mandate Territory of New Guinea and the western part of the Solomon Islands. This area was defined by the Allied powers' South West Pacific Area (SWPA) command.
The Pacific Ocean theater of World War II was a major theater of the Pacific War, the war between the Allies and the Empire of Japan. It was defined by the Allied powers' Pacific Ocean Area command, which included most of the Pacific Ocean and its islands, while mainland Asia was excluded, as were the Philippines, the Dutch East Indies, Borneo, Australia, most of the Territory of New Guinea, and the western part of the Solomon Islands.
The strategic operations of the Red Army in World War II were major military events carried out between 1941 and 1945 on the Eastern Front or in 1945 in the Far East during the Second World War. Such operations typically involved at least one Front – the largest military formation of the Soviet Armed Forces. The operations could be defensive, offensive, a withdrawal, an encirclement, or a siege – always conducted by at least two Services of the armed forces and often included the naval forces. In most cases the Stavka divided the strategic operations into operational phases which were large operations in their own right. In very few cases the phases were tactical, such as those requiring amphibious landings.
Prior to World War II, the Indian Ocean was an important maritime trade route between European nations and their colonial territories in East Africa, the Arabian Peninsula, British India, Indochina, the East Indies (Indonesia), and Australia for a long time. Naval presence was dominated by the Royal Navy Eastern Fleet and the Royal Australian Navy as World War II began, with a major portion of the Royal Netherlands Navy operating in the Dutch East Indies and the Red Sea Flotilla of the Italian Regia Marina operating from Massawa.
The 41st Tactical Group is an inactive United States Air Force unit. Its last assignment was with the 7217th Air Division at Cigli Air Base, Turkey, where it was inactivated in 1970. From 1966 to 1970 the group controlled deployed fighter squadrons.
The Japanese occupation of the Gilbert Islands was the period in the history of Kiribati between 1941 and 1945 when Imperial Japanese forces occupied the Gilbert Islands during World War II, in the Pacific War theatre.
